How to remove space (before or) after comma from a string?

Question

How do I remove whitespace before or after comma? I have tried split(), but I want the result be a string as well.

Eg

string1 = "tree one two, true op op,blue io op" result = "tree one two,true op op,blue io op"

Answer 1

lstrip() will remove left blank spaces, rstrip() will remove right blank spaces, strip() will remove all blank spaces.

By the looks of it, lstrip() is what you're after.
