Remove characters in string using a variable

jaykapalczynski — Fri, 16 Sep 2022 15:22:45 GMT

I am trying to remove characters from a string but this Numeric value changes.

I'm passing in the string and the number of characters that should remain.

Below there are two ways I am trying this both doing the same thing... But the number of characters is hardcoded '75'

How do I replace the '75' with the variable 'characterLength' that is being passed into the def???

newmod2 = newmod1[: {characterLength} ]

def fModifyValue(processResults, charlength): initialMod = str(processResults) characterLength = charlength newmod1 = initialMod.replace("u'", "") newmod2 = (newmod1[:75] + '..') if len(newmod1) > 75 else newmod1 #OR newmod2 = newmod1[:75] return newmod2

Maybe

newmod2 = newmod1[: {} ].format(characterLength)

UPDATE: Nope that does not work

Ok think I got it.... BUT please if there is a better way please let me know.

def fModifyValue(processResults, charlength): initialMod = str(processResults) characterLength = int(charlength) newmod1 = initialMod.replace("u'", "").replace('[', '').replace(']', '').replace(r"'", r'') newmod2 = newmod1[:characterLength] return newmod2

Besides the variable length slicing, which you appear to have figured out, what exactly are you trying to do with all of those replace statements?

Regular expressions are your friend here. Check out the re module.

The data is coming in from a Word Press RestEP and a bit messy...
