str_1 = 'apple'

str_3 = 'orange'
len_1 = len(str_1)
len_2 = len(str_2)
len_3 = len(str_3)
print(f'str_1 is greater than str_2? {str_1 > str_2}')
print(f'The length of str_1 is {len_1}, the length of str_2 is {len_2}')
print(f'str_1 is greater than str_3? {str_1 > str_3}')
print(f'The length of str_1 is {len_1}, the length of str_3 is {len_3}')
print(f'str_2 is greater than str_3? {str_2 > str_3}')
print(f'The length of str_2 is {len_2}, the length of str_3 is {len_3}')
