1. Usingstring::rfind The standard approach to find the index of the last occurrence of a char in a string is using thestring::rfindmember function. If the character doesn’t occur in the string, the function returnsstring::npos.
my_string = "character" character = 'c' if my_string.find(character, 2, 5) != -1: print(f'\'{character}\' in \'{my_string}\'' f' exists at index {my_string.find(character, 2, 5)}') else: print(f'\'{character}\' does not exist in \'{my_string}\'') The program wi...
We’re going to use the ROW function, the INDEX function, the MATCH, the MID, and the LEN functions to create an array formula to find the position of the last occurrence of a character in a string. Steps: Input the formula below into cell D5: =MATCH(2,1/(MID(C5,ROW($C$1:IN...
