如下所示:

# -*- coding: utf-8 -*-

# 要求:输入一行字符,分别统计出其中英文字母、空格、数字和其它字符的个数。

def count(s):
count_a=count_z=count_o=count_s=0
for i in s:
if (ord(i)>=97 and ord(i)<=122) or (ord(i)>=65 and ord(i)<=90):
count_a=count_a+1
elif ord(i)>=48 and ord(i)<=57:
count_z=count_z+1
elif ord(i)==32:
count_s=count_s+1
else:
count_o=count_o+1
print "英文字母个数:%d个"%count_a
print "数字个数:%d个"%count_z
print "其他字符个数:%d个"%count_o
print "空格个数:%d个"%count_s
if __name__=="__main__":
s=raw_input("请输入一串字符:")
count(s)

运行结果:

请输入一串字符:{""O: UIK YTJ ET_+*(_^*@#%@#$^#%*&456587978957FHSJHSRHFDHDFaHSHYWER YWERF R454qggsdhshrths

英文字母个数:48个

数字个数:15个

其他字符个数:22个

空格个数:7个

总结:

ord()将字符转换为ASCII码

以上这篇python统计字母、空格、数字等字符个数的实例就是小编分享给大家的全部内容了,希望能给大家一个参考。
