How to fix appending turns my list to NoneType with Python?

To fix appending turns my list to NoneType with Python, we shouldn’t assign the return result append to the list.

For instance, instead of writing

a_list = ['a', 'b', 'c', 'd']  
a_list = a_list.append('e')  

We write

a_list = ['a', 'b', 'c', 'd']  
a_list.append('e')  

since append appends 'e' to a_list in place and returns nothing.

Conclusion

To fix appending turns my list to NoneType with Python, we shouldn’t assign the return result append to the list.
