Python统计字符串中的中英⽂字符、数字空格，特殊字符# -*- coding:utf8 -*-
import string

def str_count(s):
'''出字符串中的中英⽂、空格、数字、标点符号个数'''
count_en = count_dg = count_sp = count_zh = count_pu = 0
s_len = len(s)

# 英⽂
if c in string.ascii_letters:

# 数字
elif c.isdigit():
count_dg += 1
# 空格
elif c.isspace():
count_sp += 1
# 中⽂
elif c.isalpha():
空格字符串是什么
count_zh += 1
# 特殊字符
else:

if total_chars == s_len:

return None
if__name__ == '__main__':
str_l = "这是⼀个test字符串"
count = str_count(str_l)
print(str_l, end='\n\n')
print('该字符串共有 {} 个字符，其中有 {} 个汉字，{} 个英⽂，{} 个空格，{} 个数字，{} 个标点符号。'.al, count.zh, , count.space,
count.digit, count.punc))
namedtuple使⽤参考：
输出为：
该字符串共有 11 个字符，其中有 7 个汉字，4 个英⽂，0 个空格，0 个数字，0 个标点符号。
