for sex_group in grouped:
print('the type is: {}\n'.format(type(sex_group)))
print('the length is: {}\n'.format(len(sex_group))) # 남,녀 2개

print('what we have:')
print(sex_group)

break

강의중에 이 코딩에서 second_element인 Female 데이터가 출력이

안되고 Male만 출력이 되는 결과인데도 그냥 넘어가시길래

궁금해서 질문드립니다

Female도 

the first element is: Female

it has a type of: <class 'str'> 이 나와야하는데 

전체 Male 데이터가 나와버립니다
