Google Kickstart 2014 Round D Sort a scrambled itinerary – Do I need to bring the input in a ready-to-use array format?
Problem: Once upon a day, Mary bought a one-way ticket from somewhere to somewhere with some flight transfers. For example: SFO->DFW DFW->JFK JFK->MIA MIA->ORD. Obviously, transfer flights at a city twice or more doesn’t make any sense. So Mary will not do that. Unfortunately, after she received the tickets, she messed up the tickets and she forgot the order of
Is there a way to use python argparse with nargs=’*’, choices, AND default?
My use case is multiple optional positional arguments, taken from a constrained set of choices, with a default value that is a list containing two of those choices. I can’t change the interface, due to backwards compatibility issues. I also have to maintain compatibility with Python 3.4. Here is my code. You can see that I want my default to
Why do I need an asterisk and some random variable in these Python Tkinter functions for them to work properly?
In this basic Python Tkinter code, I’m trying to bind certain functions to trigger upon either a UI button press or a keyboard key press. After a while of trial and error, it seems to work the way I want if I add an in the declarations of: and: I get that one asterisk lets the function take an unknown

Variable Length Arguments (*args) in Python3
I am fairly new to Python3. I have a question with Variable Length Arguments(*args). Based on my understanding the reason why we use the Variable Length Arguments list(or tuple) is that they are useful when you need a function that may have different numbers of arguments. A function like this gives the same output as output I don’t see the
random number generating function as argument in python
I want to pass a function which generates random normal numbers to another function, do some calculations and pass again the random function x times. At the end there should be a Dataframe with x colums with diffrent randomly generated outcomes. My code looks like this: But this gives me always identical columns. Answer I don’t think you can pass
Output is an empty file
My code does not throw an error, it simply creates the files, but of which are empty. I tried it from the command line, and it works using the wildcard training_set_pssm/*.pssm path, but I must do it from the IDE because it is not printing the correct output anyway. The input file is a set of checkpoint files that look
Python Function parameters and arguments
I want to understand functions and arguments better, I’ve read and this is my implementation of what I have read. I have 3 small functions to illustrate my point. User input collection, grading function and main. If I run the main function without its argument (1), it results in an error looking for the argument. I know that I declared
Hardcode RF Codes in rpi-rf_send script + python raspberry pi
I’d like to hardcode the RF Code in the rpi-rf_send.py send script so I can repeatedly activate the same device automatically. I’ve reviewed all of the documentation and I cannot find any clear method to do that. Docs: https://pypi.org/project/rpi-rf/ https://github.com/milaq/rpi-rf It works well when passing the arguments directly from the terminal in this format: But what I need to do
