找到大写字母

#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')
