我该如何导入该功能？

Question

I have a Python function in a file called func.py

def calc(x,y):
    return x*y

I have to import this function while working in another file called mytask.py

How can I import the function?

Answer 1

Save the file in the same directory and then have a statement

from func import calc

To import from a different directory

1. Add the file to a new directory, call it funcs
2. Create a file __init__.py and have a line __all__ = ['calc']
3. Import as from funcs import func
