The suffix is removed if the target string ends with that exact substring. If the original string doesn’t end with suffix, then the string is returned unchanged. The .removeprefix() and .removesuffix() methods were introduced in Python 3.9. .lstrip([chars]) The .lstrip() method returns ...
str.find(str, beg=0, end=len(string)) #Determine if str occurs in string or in a substring of string if starting index beg and ending index end are given returns index if found and -1 otherwise. str.isalnum()#Returns true if string has at least 1 character and all characters are al...
