how to use function defined in other python file?
Question: Lets say we have two programs `A.py` and `B.py` ,now `B.py` has two defined
functions

`calculator(x,y)` which returns `int` and makelist(list1)`which returns`list`

Now,how can I access these functions in `A.py` (Python 3)?


Answer: You will need to import the other file, that is B, as a module

    
    
    import B
    

However, this will require you to prefix your functions with the module name.
If instead, you want to just import specific function(s) and use it as it is,
you can

    
    
    from B import *    # imports all functions from B
    
    -or-
    
    from B import calculator   # imports only the calculator function from B
    

> UPDATE

Python does not add the current directory to `sys.path`, but rather the
directory that the script is in. So, you would be required to add your
directory to either `sys.path` or `$PYTHONPATH`.
