Basically, if I have a line of text which starts with indention, what's the best way to grab that indention and put it into a variable in Python? For example, if the line is:
\t\tthis line has two tabs of indention
Then it would return '\t\t'. Or, if the line was:
this line has four spaces of indention
Then it would return four spaces.
So I guess you could say that I just need to strip everything from a string from first non-whitespace character to the end. Thoughts?

The first line of python code cannot have an indentation. Indentation is mandatory in python to define the blocks of statements. The number of spaces must be uniform in a block of code. It is preferred to use whitespaces instead of tabs to indent in python.
Spaces are the preferred indentation method. Tabs should be used solely to remain consistent with code that is already indented with tabs. Python 3 disallows mixing the use of tabs and spaces for indentation. Python 2 code indented with a mixture of tabs and spaces should be converted to using spaces exclusively.
Python 3 says: Tabs are replaced (from left to right) by one to eight spaces such that the total number of characters up to and including the replacement is a multiple of eight (this is intended to be the same rule as used by Unix).
We can use \t in the print() function to print the tab correctly in Python.
def whites(a):
return a[0:a.find(a.strip())]
Basically, the my idea is:
