a simple string comparison can be done with the == operator. print("hello world" == "hello world") will return True print("hello world!" == "helloworld!" will return False In this case we can start a character by character comparison that gives us the first match that is not equal. txt1 = "hello world!" txt2 " "helloworld!" for pos, cmp in enumerate(zip(txt1,txt2)): if cmp[0] != cmp[1]: print(f"position: {pos} with: {repr(cmp[0])} - {repr(cmp[1])}") break

Strings in python are compared lexicographically, which allows you to use the normal comparison operators (==, !=, <, >, <=, >=)
