Judging by https://pyneng.readthedocs.io/ru/latest/book/17_serialization/2_json.html :loads - takes json as a line. The code swears that "hist.json" - it's not json and he doesn't know what it is.load is loaded from the file facility. In the particular case, it should be:import json def cout(): with open('hist.json', 'r') as hist: for i in json.load(hist): print(i) cout() And the JSON-format is fighting over the extra commas, so the file needs to remove the last comma from the last part of the list.PS: A loads used:import json def cout(): for i in json.loads(""" { "db": [ { "message_id": 1156 }, { "message_id": 1155 }, { "message_id": 1154 } ] } """): print(i) cout()

I finally managed to solveIf someone ever has this problem as well, follow the solution that I found by fusing in all what kind of python site/foruns:from selenium import webdriver from selenium.webdriver.common.keys import Keys from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.common.action_chains import ActionChains import time droplist = wait.until(EC.element_to_be_clickable((By.XPATH, '//*[@id="root"]/div/section/section/main/div/div/div[2]/div/div/div[1]/div/div' ))) #encontrar botao da droplist (nesse caso achei melhor com xpath, site mal montado) ActionChains(driver).move_to_element(droplist) driver.execute_script('arguments[0].click();', droplist) wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, 'li.ant-select-dropdown-menu-item'))) drop_down_click = wait.until(EC.element_to_be_clickable((By.XPATH, '//li [text()="20"]'))) drop_down_click.click() This following the HLTM of the site I posted on images, to select the 20th minute of a game, but could be any text of this combobox droplist that was not mounted with select in html. In the second image posted are the options of this droplist, from 1 to 90... in the case above it would select the minute 20. I only posted the excerpt of this specific solution program.

You can use regular expressions to remove everything after. / And I missed you.import re re.sub(r'/.* ', '', message.text) for example message.text = /Message Привет! We'll only get out. Привет! https://regex101.com/r/prxlwf/1

You only need a couple of details in your code:letters = [['letters1', 'a', 'c', 'b', 'BUILD'], ['letter2','F', 'P', 'Z', 'W', 'SHOW', 'BUILD'], ['leters3','R', 'X', 'N', 'BUILD', 'SHOW']] max = [4, 5, 4] stringWithMax = [] def reGet(): for i in range(len(letters)): until here well, but now you have to add an empty list for each row stringWithMax.append([]) Now what's missing: for x in range(1, max[i]): stringWithMax[i].append(letters[i][x]) add the values to the new listanother thing, it's not that it's wrong, but it's better than the function to twist the list instead of showing it. return stringWithMax in the end the entire code to be understoodletters = [['letters1', 'a', 'c', 'b', 'BUILD'], ['letter2','F', 'P', 'Z', 'W', 'SHOW', 'BUILD'], ['leters3','R', 'X', 'N', 'BUILD', 'SHOW']] max = [4, 5, 4] stringWithMax = [] def reGet(): for i in range(len(letters)): stringWithMax.append([]) for x in range(1, max[i]): stringWithMax[i].append(letters[i][x]) return stringWithMax print(reGet()) all this chorrada of explanation is for those who kick by the simplified answers.

sys.path.append(r'外側のmysiteフォルダへのフルパス') This is the folder of mysite outside of PYTHONPATH.so you need to import it from the starting point. mysite.polls not polls I think that the error can be avoided# エラーになる from mysite.polls.models import PriceLog エラーにならない from polls.models import PriceLog

Whatever the reason is, anyway, it's a mistake of our favorite Kazmmerzbank.First, the client is always right.Second, it's a nunsens-- so the bank doesn't know what it is, give it a "error: java.lang.NullPointerException" and demagogic: "all work and you don't have a "upside of unprofessionalism." "NullPointerException" is not the cause, but the consequence of the error that occurred, which may be: (1) hands (and brains) not from that place of CCM programmers (mostly inclined) (2) firewall, or a breakdown of communication (3), the issue of the certificate (eicto has more clearly spelled out the possible reasons, but in this case, they should have said exactly that, not the cause of demagogic zero.Thirdly, POST is both in Kazakhstan and POST, the providers have nothing to do with it, and the employees of the bank are stupid.Fourthly, no surprise is Kazakhstan, kinship, etc.

As discussed in the comments of this question, much of the problem was solved, so I plant the solution I tried and worked, this code is taking into account that the position of the container folder of the xlsx file is known and the name of the file in question:import os import pandas as pd def some(): path = "carpeta" #esta carpeta es una subparpeta de la ubicación donde se encuentra el archivo python files=os.listdir(path) conteo_files=0 for file in files: day='23' if file.startswith('~$'): files.remove(file) if day in file: archivo = os.path.join(path,file) print(archivo) df = pd.read_excel(archivo) print(df) some() when executing this code I get as a result:carpeta\ea_23122021.xlsx a b c 0 1 4 5 1 2 3 6 >>>

According to the information you supply, I tried to recreate the information you have. Using the library pandas He thinks dataframe by name dfwith the following structure: time A 0 1552403428 16 1 1552403434 33 2 1552403403 24 3 1552403433 28 4 1552403407 20 Dimensiones: (100, 2) It contains in total 100 records generated randomly. To group by the column time You must have repeated values, otherwise the result will be the same dataframe. To check this you can run:print(f'Número de registros: {len(df)}') print(f'Número de resgistros únicos {len(pd.unique(df.time))}') Número de registros: 100 Número de resgistros únicos 50 As you see, out of 100 50 records are unique, which means that the resulting dataframe after the grouping will have 52 records. With the following code you can group by the column time and obtain the average of the column Aas you mention above. groupby_seconds = df.groupby(['time']).agg({'A': 'mean'}) print(groupby_seconds.head()) time A 0 1552403400 12.000000 1 1552403401 15.666667 2 1552403403 17.000000 3 1552403406 33.333333 4 1552403407 20.000000 Dimensiones: (50, 2) You can check the result of any of the records, in this case, I'll check the record average. 1552403401 as follows:print(df[df.time == 1552403401]) time A #21 1552403401 10 #32 1552403401 21 #97 1552403401 16 You can effectively check that the average column A is: 15.666667I hope it serves you.

Having cloud/cloud webservices has advantages and disadvantages:Advantages:it is not necessary to assemble the system which: need storage spaceneed security for data integrityneed to have backups and maintenance systems and updates runningDisadvantages:sometimes some webservices have slow connections because they are on remote servers (too far)sometimes the data we put or pass through the webservice are covered by the law of the country in which the server is and not the country of the company running itSometimes the data is not 100% conofidial, Google and Dropbox (among others) have access to the data even if it does not disclose it. Not all companies accept this reality.

You can check before the caste to whole that the entered string corresponds to a blank space "" and if so you leave the loop with a break Contador = 0 while True: try: Suma_Numeros = input('Ingrese el numero que desee sumar: ') if Suma_Numeros == " ": break Suma_Numeros = int(Suma_Numeros) Contador += Suma_Numeros print(Contador) except ValueError: print('Error en caracter ingresado, por favor ingrese solo numeros')
