The library cryptocode provides a simple way to encode and decode strings with a password. Here is how you install: pip install cryptocode. Encrypting a message (example code): import cryptocode. encoded = cryptocode.encrypt("mystring","mypassword") ## And then to decode it:
This is probably a trivial question, but how do I parallelize the following loop in python? # setup output lists. output1 = list() output2 = list() output3 = list() for j in range(0, 10): # calc individual parameter value. parameter = j * offset. # call the calculation.
Here is the simplest python socket example. Server side: import socket serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) serversocket.bind(('localhost', 8089)) serversocket.listen(5) # become a server socket, maximum 5 connections while True: connection, address = serversocket.accept() buf = connection.recv(64) if len(buf) > 0: print buf break
Blog post Serial RS232 connections in Python. import time import serial # configure the serial connections (the parameters differs on the device you are connecting to) ser = serial.Serial( port='/dev/ttyUSB1', baudrate=9600, parity=serial.PARITY_ODD, stopbits=serial.STOPBITS_TWO, bytesize=serial.SEVENBITS ) ser.isOpen() print 'Enter your commands below.\r\nInsert "exit" to leave the ...
The solution is simple: Just preserve the message string as it was before. This can be done by a function (as Zeeshan suggested) or right away in the source code: import smtplib. def sendMail(FROM,TO,SUBJECT,TEXT,SERVER): """this is some test documentation in the function""".
Python 3.7+ now has a simpler API (in my opinion) with a simpler wording (easier to remember than "ensure_future"): you can use create_task which returns a Task object (that can be useful later to cancel the task if needed).
I'm trying to create a simple Caesar Cipher function in Python that shifts letters based on input from the user and creates a final, new string at the end. The only problem is that the final cipher text shows only the last shifted character, not an entire string with all the shifted characters. Here's my code:
createLogin = raw_input("Create login name: ") if createLogin in users: # check if login name exist in the dictionary. print "Login name already exist!\n". else: createPassw = raw_input("Create password: ") users[createLogin] = createPassw # add login and password. print("\nUser created!\n") elif status == "y": #login the user.
In future, to format your code you can highlight all of it and press the format code button in the editor, it looks like this: {} – Nick is tired Commented Apr 11, 2018 at 8:40
import cProfile. cProfile.run('foo()') Even more usefully, you can invoke cProfile when running a script: python -m cProfile myscript.py. Or when running a module: python -m cProfile -m mymodule. To make it even easier, I made a little batch file called 'profile.bat': python -m cProfile %1. So all I have to do is run:
