Would a multi-point function be a function if it was caused inside a multi-point function? Python, threading

Example:
```
def foo():
  bar()
def bar():
  print("Hello world")
for i in range (ThreadCount):
  thread = threading.Thread(target=foo)
```
Will the bar be met by several flows, or is its enforcement going to the main flow?

Whether the challenges of functions in many flows or not depend on the function itself, if one flow is to be performed, add 10 more flows, each of which causes your function.
Functions are not performed by several flows unless you send them clearly to several flows.
target=foo Says after the flow start (if added) thread.start() Call your code, foo() I'm going to do it. foo() In turn, new flows may be created or a function may be transferred to another stream of Pitton founciation as arguments to other functions (as if target=foo Demonstrated.
In your case bar() I'm just calling. foo() That's why naturally. bar() It'll be in the same flow as it is. foo()♪ If you'll miss it. foo() mainly flow, bar() It's going to be mostly flow.

Fix a demo in https://codesandbox.io/s/hardcore-oskar-zq7vs that certainly does not match the functionality you want, but exemplifies how to import files and extract hooks. To reuse code, use import. You typically import functions, classes or constants.import React, { useState, useEffect } from "react"; import api from "../utils/fakeApi"; import Transaction from "./Transaction"; To reuse life cycle, https://pt-br.reactjs.org/docs/hooks-custom.html . By convention, a hook should start with use and have a name that starts with capital soon after.import { useState, useEffect } from "react"; import api from "../utils/fakeApi"; export default function useTransaction(dateSelected) { const [transactions, setTransactions] = useState([]); useEffect(() => { async function loadTransaction() { const response = await api.get("/search?yearMonth=" + dateSelected); setTransactions(response.data.transaction); } loadTransaction(); }, [dateSelected]); return transactions; } Do not confuse hooks with UI components. These return components and can (or not) use hooks. Functions or IU classes should start with capital letter.import React from "react"; import useTransaction from "../hooks/useTransaction"; export default function Transaction({ dateSelected }) { const transactions = useTransaction(dateSelected); return ( <div> <h2>transactions</h2> <p>para {dateSelected.toDateString()}:</p> <ul> {transactions.map(item => ( <li key={item}>{item}</li> ))} </ul> </div> ); }

I don't quite understand the question, if I did the right thing, the answer is:Set up another list_no with no answers. That's it.if returns_2 in list_yes: pass elif returns_2 in list_no: pass else: continue == Compars the answer to the list (not correct)in == sync, corrected by elderman == @elder_manpass Don't do anything.continue Makes the cycle and asks the question first.To accept and take a tight and basic: Put all the words on the list with small letters and fix:input('Ещё раз? [да/нет]: ') On:str(input('Ещё раз? [да/нет]: ')).lower() The user's response will be written in small letters and will be matched with small letters, too.

You're rewriting the file. C:\\abc\out.txt in the cycle for each line of the input file. Ultimately, the exit file will be the result of processing the last line of the entry file.Try this:with open(r'd:\temp\in.txt', 'r') as f, open(r'd:\temp\out.txt', 'w') as out: for line in f: print(str(bool(eval(line))), file=out) NOTE: https://www.floyd.ch/?p=584 I'd rather not use it at all.

You do not have a function there, you have a method, at least by the convention adopted that if you have a self as a parameter is a method, so methods can only be called through an object, cannot be called directly.When you called it conta1.soma() you called for a method, passing the object, but when you called for soma() + 10 did not use any object to pass to the parameter self. As the only object you have within the method somadez() it is self it gets easy to solve, just use it as an object to call the desired method.class op(): def __init__(self, num1, num2): self.x = num1 self.y = num2 def soma(self): return self.x + self.y def somadez(self): return self.soma() + 10 conta1 = op(1, 2) print(conta1.soma()) print(conta1.somadez()) See https://ideone.com/OZA9Sl . And https://repl.it/@maniero/OrderlyDistantSquare . Also https://github.com/maniero/SOpt/blob/master/Python/OOP/SelfEscope.py .Note that Python has a syntax sugar that allows to call the method by passing the object to the self with the notation of the object before the method.This has nothing to do with function within function. è on the scope of self, it is not worth for every class, it needs to be passed explicitly.

This is because your program is synchronous. That means he only does one thing at a time. When you call sleep, the program stops running to sleep that certain time, and while sleeping it neither updates the screen and nor hears the interface to know if the user has given some command; in this, it gets locked, even though it comes back when the time ends "sleeping".The solution is to use the function after Tk. You pass to it the number of milliseconds you want to wait and a function; the Tkinter then performs that function after the number of milliseconds.That means you have to split your function pomodoro in some parts, so you can wait between them. As we also have to remember in which cycle we are in different functions, we add a global variable. Here, I called her ciclo_atual, and kept the 3s waiting for the original code:from tkinter import * Quando o botão é clicado, resetamos o contador de ciclo atual e iniciamos o primeiro ciclo. def pomodoro(): global ciclo_atual ciclo_atual = 0 iniciar_ciclo() Quando iniciamos um ciclo, verificamos se o contador extrapolou a quantidade de ciclos desejada. Se não, chamamos a função iniciar_intervalo depois de 3000 milisegundos. def iniciar_ciclo(): global ciclo_atual lb_acao['text'] = 'Pomodori' lb_acao['bg'] = 'red' qt_ciclos = int(ed_ciclos.get()) lb_ciclos_restantes['text'] = qt_ciclos - ciclo_atual if ciclo_atual < qt_ciclos: ciclo_atual += 1 win.after(3000, iniciar_intervalo) Ao iniciar o intervalo, atualizamos a interface e chamamos novamente a função iniciar_ciclo depois de 3000 ms. def iniciar_intervalo(): lb_acao['text'] = 'Intervalo' lb_acao['bg'] = 'green' win.after(3000, iniciar_ciclo) win = Tk() Components lb1 = Label(win, text='Tempo útil: ') ed_tempo = Entry(win) lb2 = Label(win, text='Tempo de intervalo: ') ed_intervalo = Entry(win) lb3 = Label(win, text='Quantidade de ciclos: ') ed_ciclos = Entry(win) btn = Button(win, text='Começar', command=pomodoro) lb4 = Label(win, text='Ciclos restantes:') lb_ciclos_restantes = Label(win, text='0') lb5 = Label(win, text='Modo:') lb_acao = Label(win, text='Preparado') lb6 = Label(win, text='Tempo:') lb_time = Label(win) GUI lb1.grid(row=0, column=0) ed_tempo.grid(row=0, column=1) lb2.grid(row=1, column=0) ed_intervalo.grid(row=1, column=1) lb3.grid(row=2, column=0) ed_ciclos.grid(row=2, column=1) btn.grid(row=3, column=0, columnspan=2, sticky=W+E) lb4.grid(row=4, column=0) lb_ciclos_restantes.grid(row=4, column=1) lb5.grid(row=5, column=0) lb_acao.grid(row=5, column=1) lb6.grid(row=6, column=0) lb_time.grid(row=6, column=1) Program win.mainloop()

Do you want to remove the User and Group model from Admin.

Jinja2 - It's just a library to facilitate the generation. HTML pages. And the task you need is solved by simple means. HTTP requests that can be made as clean HTMLand more flexible JavaScript'a. In any case, a request processor on the north side is needed to transfer data to the server.1.1. Net HTML + hidden parametersWith the goal of a clean HTML, the page will be reloaded. Such forms should be made on the page:<form action="/process_data/" method="POST">  <input type="hidden" name="index" value="1"> <input type="submit" class="btn btn-dark" value="Нажать 1"> </form> <form action="/process_data/" method="POST">  <input type="hidden" name="index" value="2"> <input type="submit" class="btn btn-dark" value="Нажать 2"> </form> And in the earring, catch these actions and parameters:@app.route('/process_data/', methods=['POST']) def doit(): index = request.form['index'] # ... обработать данные ... 1.2. Net HTML +Flask makes it easy to process arguments as part of the way: <form action="/process_data/1/" method="POST"> <input type="submit" class="btn btn-dark" value="Нажать 1"> </form>  <form action="/process_data/2/" method="POST"> <input type="submit" class="btn btn-dark" value="Нажать 2"> </form> And in the earring,@app.route('/process_data/<index>/', methods=['POST']) def doit(index): # ... обработать данные ... 1.3. Net HTML + JSON formThe format can be set, then the supporters of the JSON will send the data in the right format, and not the supporters will return to classical. form url encoded:<form action="/process_data/" enctype="application/json" method="POST">  <input type="hidden" name="index" value="1"> <input type="submit" class="btn btn-dark" value="Нажать 1"> </form> <form action="/process_data/" enctype="application/json" method="POST">  <input type="hidden" name="index" value="2"> <input type="submit" class="btn btn-dark" value="Нажать 2"> </form> More details and real interesting examples with the JSON form are available downstairs on reference No. 5.It's easy to catch JSON on the server, too:@app.route('/process_data/', methods=['POST']) def doit(): data = request.get_json(silent=True) index = data["index"] # ... обработать данные ... 2. HTML + JavaScriptIt is clear that the methods above suggest a repetitive HTML code, which is obviously uncomfortable, especially if you want to change something. JavaScript may significantly simplify the code by providing greater flexibility and by not reloading the page when sending the data:<button type="button" class="btn btn-dark" onclick="process(1);">Нажать 1</button> <button type="button" class="btn btn-dark" onclick="process(2);">Нажать 2</button> The specific format of the request will now be defined in only one place. The violin itself can do differently.For simplicity, JS is used in connection with the jQuery library.2.1. Server option 1.1where the data are transmitted to HTTP by reason:function process(index) { $.post("/process_data/", {'index': index}, function (data, status) { alert(Data: ${data}\nStatus: ${status}); }); } 2.2. Server option 1.2.where the data is transmitted as part of the journey:function process(index) { $.post(/process_data/${index}/, {}, function (data, status) { alert(Data: ${data}\nStatus: ${status}); }); } 2.3. And finally, the server option. 1.3.c JSON on board:function process(index) { $.ajax({ url: "/process_data/", type: "POST", contentType: "application/json", data: {"index": index}, success: function (data) { alert(data); }, }); } This option, through JSON, can easily be combined with the previous one where something passes through URI. It is often useful in developing this, for example, to create and edit a certain substance on the website (aquaint, page or product) by a number or slug identifier as part of the route, and the description/content is sent to the request.It is worth noting that HTTP is only beginning to do so: there are different types of methods (GET, POST, PUT, DELETE, etc.) that also have an important service load for the server, there are boxes/cookies, headings/headers, HTTP status codes that also help to transmit information between the client and server. But that's all the research materials. :)Useful and used materials http://flask.pocoo.org/docs/0.12/quickstart/ (who actually has everything necessary) https://www.w3schools.com/jquery/jquery_ajax_get_post.asp https://stackoverflow.com/a/8517361/5308802 https://stackoverflow.com/q/20001229/5308802 https://darobin.github.io/formic/specs/json/

I believe you need to declare a new variable by passing name.upper() in this new and then print or else put the function upper() directly inside the print to work. What's going on is that you're using upper() and then on the bottom line where it prints this is no longer being used.
