[FIXED] Is there an elegant way to reset system method names after you reassign them?

Issue

This may be a duplicate but I couldn't find any post about it so if it is, please link me to the post.

If I have a block of code in an ipython notebook:

input = input("enter some info")

then when I rerun the same block of code, it will give me an error of

TypeError: 'str' object is not callable

Even if i rename the variable name, I still get the same error. How can I get back the original functionality of the input method without needing to restart the entire jupyter notebook?

Thanks

Solution

Best practice is to not use any system names like input, min, max, etc. Instead use another name entirely, or at least put a trailing underscore: input_, min_, max_. But if it's unavoidable:

IPython's reset will reset all names. Example usage:

In [1]: input = input("Enter some info: ")
Enter some info: hello

In [2]: input
Out[2]: 'hello'

In [3]: reset
Once deleted, variables cannot be recovered. Proceed (y/[n])? y

In [4]: input
Out[4]: <function input>
