# function voting_age(): returns how old you need to be to vote; i.e. the
#     integer 18.

def voting_age():
    result = 18
    return result

# def voting_age():
    # return 18
# Also works ^

# function has_blanks( s ): returns a whether s contains at least one blank
#     character; i.e., returns True if s contains a blank, and returns
#     False otherwise.

def has_blanks( s ): # This function has a single parameter s
    # print( 's=', s )
    if ( ' ' in s ):
        return True
      #   result = True
    else:
        return False
        # result = False
    # return None

# Another way:
# def has_blanks( s ):
    # count_blanks = s.count(' ')
    # if (count_blanks > 0):
        # return True
    # else:
        # return False

# function great_seal( ): prints the string 'E Pluribus Unum'

def great_seal():
    print( 'E Pluribus Unum' )

# function a_ing( n ) prints n lines of output. The first line prints a
#     single 'a', the second line prints 'aa', the third line prints 'aaa',
#     and so on.

def a_ing( n ): # n is the parameter and we print n lines of output with n a's per line
    for num_of_as in range(1, n+1):
        output = 'a' * num_of_as # repeated string concatenation
        print( output )
