#解法一
def capitals(a):
for index,s in enumerate(a):
#isupper 如果字符串中都是大写，返回True，如果有一个小写，返回False
if s.isupper():
print(index)
capitals('anMIE')
#解法二
def capitals(word):
capitals_index=[]
for i in range(len(word)):
if word[i].isupper():
capitals_index.append(i)
return capitals_index
print(capitals('CodEWaRs'))
#解法三
def capitals(word):
return [i for i,s in enumerate(word) if 'A' <= s <= 'Z']
capitals('CodEWaRs')
