Python에서 목록 첨자와 그 값을 얻는 간단한 방법

for item in sequence:
    process(item)

for index in range(len(sequence)):
    process(sequence[index])

enumerate(sequence,start=0)

>>> seasons = ['Spring', 'Summer', 'Fall', 'Winter']
>>> list(enumerate(seasons)) [(0, 'Spring'), (1, 'Summer'), (2, 'Fall'), (3, 'Winter')]
>>> list(enumerate(seasons, start=1)) [(1, 'Spring'), (2, 'Summer'), (3, 'Fall'), (4, 'Winter')]

for index,item in enumerate(sequence):
    print index,item
