Use the str.count() method to check if a character appears twice in a string, e.g. if my_str.count(char) == 2:. The str.count() method returns the number of occurrences of a substring in a string. main.py my_str = 'bobbyhadz.com' if my_str.count('o') == 2: # 👇️...
The islapha() function checks whether a character is an alphabet or not. #include <ctype.h> #include <stdio.h> int main() { char c; int lowercase_vowel, uppercase_vowel; printf("Enter an alphabet: "); scanf("%c", &c); // evaluates to 1 if variable c is a lowercase vowel ...
