Remove characters in string using a variable

jaykapalczynski

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

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
