python - Naming conflict with built-in function

Question

I have made a mistake as below:

>>> list = ['a', 'b', 'c']

But now I want to use the built-in function list(). As you can see, there is a naming conflict between listname list and the built-in function list().

How can I use list as a built-in function not the variable without restarting the Python shell?

Answer 1

Step one: rebind the list to a different name

lst = list

Step two: delete the list variable

del list

Step three: don't do it again

I prefer this over __builtins__.list simply because it saves the typing, and you aren't still left with a variable named list. However, it is always best to avoid the problem altogether. When writing production code, always remember not to have variables named the same as built in functions.
