Python striping extra characters

Question

I'm trying to understand what string.strip() in python is doing:

In [35]: t1 = '-MIN-North'

In [36]: t1.strip('-MIN-')
Out[36]: 'orth'

In [37]: t2 = '-MIN-north'

In [38]: t2.strip('-MIN-')
Out[38]: 'north'

Why is t1.strip('-MIN-') not equal to 'North' but t2.strip('-MIN-') equal to 'north'?

strip is taking out all the characters you provide it in the argument.

In your first example, it is stripping out the N from North because N is in -MIN-.

In the second, it is not stripping the n from north because n is not in -MIN-.

Thanks, that's interesting can strip be applied with an exact match? Or would regex be needed here – Umar.H Oct 09 '18 at 16:56

A regex would work, alternatively: `t1.replace('-MIN-','')` – sacuL Oct 09 '18 at 18:28
