统计一行字符的大写字母，小写字母和数字的个数

哈喽，有用请点采纳~

s = input()
str_upper, str_lower, n = 0, 0, 0
for i in s:
    if i.islower():
        str_lower += 1
    elif i.isupper():
        str_upper += 1
    elif i.isdigit():
        n += 1
print(str_upper)
print(str_lower)
print(n)

用请点采纳
代码：

输出：

strs = input("请输入统计字符串：")
lower_count = 0
upper_count = 0
num_count = 0

for item in strs:
  if item.islower():
    lower_count += 1
  if item.isupper():
    upper_count += 1
  if item.isdigit():
    num_count += 1

print(upper_count, lower_count, num_count, sep=',')
