检查列表内字符串中的大写字母

str_list = ["This","is","not a Red","","Wine, but a white One"]
new_list=[]
string=''
for i in str_list:
    print i
    words=i.split(' ')
    print words
    for x in words:
        if x == ' ' or x=='':
            new_list.append(x)

        elif x[0].isupper() and string != '':
            string=string.strip()
            new_list.append(string)
            new_list.append(x)
            string=''
        elif x[0].isupper() and string == '':
            new_list.append(x)

        else:
            string=string+x+' '
print new_list
