Question

Write a recursive function named get_first_capital(word) that takes a string as a parameter and returns the first capital letter that exists in a string using recursion. This function has to be recursive; you are not allowed to use loops to solve this problem.

Test:                                                 Except:
print(get_first_capital('helLo'))                     L

s = 'great'             
print(get_first_capital(s))                           None

And

Write a recursive function named count_uppercase(my_string) that finds the number of uppercase letters in the parameter string. Note: This function has to be recursive; you are not allowed to use loops to solve this problem!

You may want to use a helper function to do the counting. The helper function header is:

def count_uppercase_helper(a_string, index):

Test: Except:

print(count_uppercase('This is a Test'))               2

def get_first_capital(word):
    if(len(word)==0):
        return None
    else:
        if(word[0].isupper()):
            return word[0]
        else:
            return get_first_capital(word[1:])

# Testing
print(get_first_capital('helLo'))
s = 'great'
print(get_first_capital(s))

======================================

def count_uppercase(my_string):
    if (len(my_string) == 0):
        return 0
    else:
        if (my_string[0].isupper()):
            return 1 + count_uppercase(my_string[1:])
        else:
            return count_uppercase(my_string[1:])

# Testing
print(count_uppercase('This is a Test'))
