Import function from other file in python
Question: In `otsu.py` I have:

    
    
     def Hello(n):
        print "Hello",n
     print "abc"
     exit()
    

In `another.py`

    
    
    from otsu import Hello
    Hello(5)
    

When I run `python another.py`, the output is `abc`, not `Hello, 5`.

What am I doing wrong?


Answer: Firstly, make sure you don't have any stale `.pyc` or `.pyo` files in the
directory. Or if you're using Python 3 then remove the `__pycache__` directory
just to be sure. This is likely the problem.

In `another.py`, running `from otsu import Hello` should print `abc`. Then
running `Hello(5)` will produce `Hello 5`. So your output will look like:

    
    
    abc
    Hello 5
    

I just ran this to confirm and it worked as expected.
