Makes a mistake of sitaxis python3.

In fact, any use of trying makes a mistake.
Two questions why and what to do

You can just put the necessary module in the project director's office with the team. pip install <library_name> -t ./ In the original file. Or it's better not in the root, but in the special, not to smash the project. Example:Fail somelib.py in the file. libs:CONST = 3.141519265358979 Fail main.py In the original directory:# Добавление папки libs в интерпретатор Питона import sys import os cwd = os.getcwd() sys.path.append(os.path.join(cwd, 'libs')) Теперь можно легко использовать любые модули из libs from somelib import CONST print(CONST) And then you can set up a new team. pip install -t lib/ <library_name>♪ In fact, the project preparation information is available on the AWS website: https://aws.amazon.com/premiumsupport/knowledge-center/build-python-lambda-deployment-package/

Let's go somewhere:To get the style you show on the chart the simplest thing is to use the style that comes already predefined in Matplotlib, https://matplotlib.org/2.1.1/gallery/style_sheets/dark_background.html . It would also be possible to do so by manually changing the color to each element of course.To embezzle the graph in your Qt the simplest and most direct application is that you use the backend that provides matplotlib, specifically https://matplotlib.org/2.0.0/api/backend_qt5agg_api.html#matplotlib.backends.backend_qt5agg.FigureCanvasQTAgg . It's currently one more widget, so you can handle it as such.To allow drag and drop files to scan you must enable Drag and Drop in the widget using the method Qwidget.setAcceptDrops(True) and overwrite the event dropEvent so that when the file is released above the widget the necessary code is executed to generate the spectragram.The code as an example could be something like this:import sys import matplotlib matplotlib.use('Qt5Agg') from PyQt5 import QtCore, QtWidgets import matplotlib.pyplot as plt from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas from matplotlib.figure import Figure import soundfile as sf class Spectrograph(FigureCanvas): def init(self, parent=None, width=5, height=4, dpi=100): plt.style.use('dark_background') self.fig = Figure(figsize=(width, height), dpi=dpi) self.axes = self.fig.add_subplot(111) self.cbar = None self.compute_initial_figure() super(Spectrograph, self).__init__(self.fig) self.setParent(parent) FigureCanvas.setSizePolicy(self, QtWidgets.QSizePolicy.Expanding, QtWidgets.QSizePolicy.Expanding) FigureCanvas.updateGeometry(self) self.setAcceptDrops(True) def dragEnterEvent(self, e): if e.mimeData().hasFormat('text/uri-list'): e.accept() else: e.ignore() def dropEvent(self, e): if e.mimeData().hasUrls: for url in e.mimeData().urls(): e.setDropAction(QtCore.Qt.CopyAction) e.accept() file = str(url.toLocalFile()) self.update_graph(file) else: e.ignore() def update_graph(self, file): self.axes.cla() if self.cbar: self.cbar.remove() data, samplerate = sf.read(file) y = data.sum(axis=1)/2 Pxx, freqs, bins, im = self.axes.specgram(y, NFFT=256, Fs=samplerate, cmap='jet') plt.gcf().set_size_inches(10,5) self.axes.set_xlim(0, len(y) / samplerate) self.axes.set_ylim(0, 23000) self.cbar = self.fig.colorbar(im) self.cbar.set_label('Intensidad (dB)') self.axes.set_xlabel('Tiempo (s)') self.axes.set_ylabel('Frecuencia (Hz)') self.a = 0 self.draw() def compute_initial_figure(self): pass class ApplicationWindow(QtWidgets.QMainWindow): def init(self): QtWidgets.QMainWindow.init(self) self.setAttribute(QtCore.Qt.WA_DeleteOnClose) self.setWindowTitle("Audio Spectrograph") self.main_widget = QtWidgets.QWidget(self) self.graph = Spectrograph(self.main_widget, width=5, height=4, dpi=100) layout = QtWidgets.QVBoxLayout(self.main_widget) layout.addWidget(self.graph) self.main_widget.setStyleSheet("QWidget {background-color: black}") self.main_widget.setFocus() self.setCentralWidget(self.main_widget) if name == "main": app = QtWidgets.QApplication(sys.argv) window = ApplicationWindow() window.show() sys.exit(app.exec_()) Note: I haven't touched the way you get the audio file data and the graphics, it's just adapted. All this procedure is done within the method SpectroGraph.update_graph in this case. And this is behavior:

You should define yourself. TextView so since the error is telling you that you're trying to use a null reference method:TextView Lab=(TextView)findViewById(R.id.lab_con); Another problem that occurs to me is that you don't have any TextView with that id (R.id.lab_con). Check your settings XML.

Fake a n instead of connect would be connect mysql_connect(blabla);, besides I must warn that in future versions of PHP (3 years?) your code will no longer work, and if you are working for a client, this will be bad, since mysql_connect was discontinued (it will be removed in the future), furthermore it is more insecure.I suggest you start using mysqli or PDO, links of basic tutorials: http://blog.thiagobelem.net/guia-pratico-de-mysqli-no-php/ (mysqli) http://www.rafaelwendel.com/2011/12/tutorial-pdo-php-data-object/ (PDO)I hope I helped.

It's not gonna be possible to intercept because OutOfMemoryError is not Exception, it's Error. Try to intercept this design: try{ // Запрос } catch (OutOfMemoryError E){ // Обработка ошибки } Good example http://www.quizful.net/post/java-exceptions ♪

Is it possible to do this with the "transformed" lists to strings?Yeah, it's possible.As I imagine you're studying, I'm gonna show you what I think is the most Easy. to solve it:# En python, los strings pueden ser cortados/accedidos como si fuesen una lista! frase = "Hola mundo!" # Esto imprimirá solo los 4 primeros caracteres de la variable print(frase[0:4]) Y esto imprimirá toda la frase, pero letra a letra for i in range(0, len(frase)): print(frase[i]) Con un loop de ese estilo podrás hacer lo que necesitas. Tan solo queda una cosita... Dices que quieres imprimir ambos juntos, qué tal si usamos format para ello? for i in range(0, len(frase)): # El método format() acepta tantos parámetros como símbolos {} haya en el string! print("La letra en la posicion {} es: {}".format(i, frase[i])) # Esto nos imprimirá La letra en la posicion 0 es: H, y así con todas las letras! You could also print it without using it format()But I think which is a somewhat more correct way of doing it and surely it will suit you well for the future.I've left the explanations in the comments. Good luck with exercise!

The error occurs because dataAtual was not initiated.Start this variable:Date dataAtual = new Date(); Another thing is to always check if the rescued value of the component is not null, and use before to compare if a date is previous to another.To also check if the difference between the years of the dates is greater than 12, without leaving much of your code and using as a basis https://stackoverflow.com/a/10215152/5524514 , I made some modifications to your method:private boolean testeData() { //data não pode ser menor que 12 boolean dataValida = false; Date dataNascimento = dataNasc.getDate(); if (dataNascimento != null && dataNascimento.before(dataAtual)) { Calendar cDataAtual = new GregorianCalendar(); Calendar cDataNasc = new GregorianCalendar(); cDataAtual.setTime(dataAtual); cDataNasc.setTime(dataNascimento); int diferenca = cDataAtual.get(Calendar.YEAR) - cDataNasc.get(Calendar.YEAR); if (cDataAtual.get(Calendar.MONTH) < cDataNasc.get(Calendar.MONTH) || cDataAtual.get(Calendar.MONTH) == cDataNasc.get(Calendar.MONTH) && cDataAtual.get(Calendar.DAY_OF_MONTH) < cDataNasc.get(Calendar.DAY_OF_MONTH)) { diferenca--; } dataValida = diferenca >= 12 ? true : false; } return dataValida; } Thus, it is enough to validate the return of the method if true, the date is greater than 12 years if false, it is less than 12.See the test: As I mentioned in the other answer, it is interesting that you use https://pt.stackoverflow.com/a/177130/28595 , and this is very well explained all your use right here on the site.

You really try to import a package, not a module. Before Python 3.3 (only regular packages) it was necessary to add a file __init__.py empty in the directory that forms the package for Python to treat it as such. From Python 3.3 (introdution of the namespace packages) it is not necessary to do this explicitly ( https://www.python.org/dev/peps/pep-0420/ ) for Pyton to consider it a package.As I suppose you use Python 한= 3.3, Python is already trying Command Like a package. The real problem is when you matter Command, the interpreter searches for directories in PYTHONPATH until he finds the directory but does not scan that directory recursively and automatically imports all the .py files he finds. I mean, suma.py It's not imported.You have several options:Without making use of the file __init__.py (namespace package) or using a file __init__.py (regular package):import Command.suma print(Command.suma.suma_1(1, 3)) or:from Command import suma print(suma.suma_1(1, 3)) Making use of a file __init__.py content:Create a file called __init__.py inside Command and add the line:from . import suma Now you can import as you did in your code:import Command print(Command.suma.suma_1(1, 3)) The file __init__.py is executed implicitly and the objects defined in it are linked to names in the package namespace.

If we enable the debugger with this code: app = flask.Flask(__name__) app.debug = True That only enables the debugger with the built-in dev server. To use the Werkzeug debugger with another WSGI server, we have to explicitly include the middleware: from werkzeug.debug import DebuggedApplication from waitress import serve app = DebuggedApplication(app, evalex=True, pin_security=False) serve(app, listen='*:8080') When you do this, with evalex and pin_security options as above, the app is trivially vulnerable to remote compromise.
