For example string s   U 007c    To remove only the parentheses from s  try the below one   import re a re sub          s  b re sub          a  print b

strip only strips characters from the very front and back of the string   To delete a list of characters  you could use the string s translate method   import string name    Barack  of Washington   table   string maketrans            print name translate table       lt  gt      Barack of Washington

string translate with table None works fine    gt  gt  gt  name    Barack  of Washington    gt  gt  gt  name   name translate None        lt  gt     gt  gt  gt  print name Barack of Washington

Because that s not what strip   does  It removes leading and trailing characters that are present in the argument  but not those characters in the middle of the string   You could do   name  name replace          replace          replace       or   name     join c for c in name if c not in       lt  gt      or maybe use a regex   import re name  re sub        lt  gt         name

Because strip   only strips trailing and leading characters  based on what you provided  I suggest    gt  gt  gt  import re  gt  gt  gt  name    Barack  of Washington    gt  gt  gt  name   re sub            lt  gt         name   gt  gt  gt  print name  Barack of Washington

I did a time test here  using each method 100000 times in a loop   The results surprised me    The results still surprise me after editing them in response to valid criticism in the comments    Here s the script   import timeit  bad chars         lt  gt    setup      import re import string s    Barack  of Washington   bad chars         lt  gt   rgx   re compile    s     bad chars      timer   timeit Timer  o      join c for c in s if c not in bad chars    setup setup  print  List comprehension      timer timeit 100000    timer   timeit Timer  o  rgx sub     s    setup setup  print  Regular expression     timer timeit 100000   timer   timeit Timer  for c in bad chars  s   s replace c        setup setup  print  Replace in loop     timer timeit 100000   timer   timeit Timer  s translate string maketrans            bad chars    setup setup  print  string translate     timer timeit 100000    Here are the results   List comprehension   0 631745100021 Regular expression   0 155561923981 Replace in loop   0 235936164856 string translate   0 0965719223022   Results on other runs follow a similar pattern   If speed is not the primary concern  however  I still think string translate is not the most readable  the other three are more obvious  though slower to varying degrees
