Question

Why can't I get this to display the results?

def main():
    try:
        string = input('Enter a string: ')
#Set Character frequency and occurrence to 0
        character_frequency = 0
        character_occurrence = 0
#Create loop to count characters
        for character in string:
            compare = 0
            occurrence = 0
        while compare < len(string):
            if character.lower() == string[compare].lower():
                compare += 1
                occurrence += 1
        if occurrence > character_occurrence and character != '':
            character_occurrence = occurrence
            character_frequency = character
          
        print('The most frequent character in the string is: ',character_frequency)
    except IOError:
        print('File could not be found')
    except:
        print('Unexpected Error occurred')
main()
