Write a Python program to split a string on the last occurrence of the delimiter. Sample Solution: Python Code: # Define a string 'str1' containing a comma-separated list of characters.str1="w,3,r,e,s,o,u,r,c,e"# Split the string 'str1' into a list of substrings using the '...
the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements). If maxsplit is not specified, then there is no limit on the number of splits (all possible splits are made...
