On each iteration, we use the str.count() method to check if the character appears more than once in the string. If the condition is met, we return True and exit the function. If the condition is never met, the string doesn't contain any repeated characters and False is returned....

If each ASCII value is greater than 97, then True is returned, or else False is returned. Example In the below given example, we are writing a function checkLower() and comparing the ASCII values for every character in that string. If every character's ASCII value is greater than 96 ...
To find the character in a string in Python: Use the find() method to find the index of the first occurrence of the supplied character in the input String. Use an if statement to check if the returned index is not -1; if so, print that index; otherwise, print an error. Use find(...
