● enumerate 이용

for i, v in enumerate(['a','b','c']):
    print(i,v)

0 a

1 b

2 c

 

mylist=['apple', 'banana', 'grape']
result=list(enumerate(mylist))
print(result)

[(0, 'apple'), (1, 'banana'), (2, 'grape')]

 

# for loop를 이용해서 리스트를 대문자로
tv = ["Good", "Bad", "Python"]
for i, show in enumerate(tv):
    new = tv[i]
    new = new.upper()
    tv[i] = new
print(tv)

['GOOD', 'BAD', 'PYTHON']
