用python编写函数hanzi

下面的这个代码可能无法成功运行所以只能浏览别抄了

data = input("请输入一些字符串：")
def hanzi_count(str):

    a = 0
    b = 0
    c = 0
    d = 0
for i in data:
    if i.isdigit():
        a = a+1
    elif i >= 'a' and i <= 'z':
         b = b+1
    elif i>='A' and i<='Z':
        b=b+1
    elif i>= u'u4e00' and i <= u'u9fa5':
        c = c+1
else:
    d = 0
print("数字个数:", a)
print("字母个数:", b)
print("汉字个数:", c)
print("其他字符个数:", d)
hanzi_count()

data=input("请输入一些字符串：")
a = 0
b = 0
c = 0
d = 0
for i in data:
    if i.isdigit():
        a = a+1
    elif i >= 'a' and i <= 'z':
         b = b+1
    elif i>='A' and i<='Z':
        b=b+1
    elif i>= u'u4e00' and i <= u'u9fa5':
        c = c+1
else:
    d = d+1
print("数字个数:", a)
print("字母个数:", b)
print("汉字个数:", c)
print("其他字符个数:", d)
