【开发该软件的操作系统】：windows10

【软件开发环境/开发工具】：PyCharm

【编程语言】：Python

【开发目的】：这是老师布置的作业啦~ 供初学者参考学习

代码如下：

(1)

#统计不同字符的个数
character = input('请输入任意字符：')
i = number = space = other = letter = 0
for i in range(len(character )):
    if 'a' <= character [i] <= 'z' or 'A' <= character [i] <= 'Z':
        letter += 1
    elif '0' <= character [i] <= '9':
        number += 1
    elif character [i] == ' ':
        space += 1
    else:
        other += 1
print("字母个数为：",letter,'t',"数字个数为：",number,'t',"空格个数为：",space,'t',"其他字符个数为：",other)

(2)

#统计不同字符的个数
character =input('请输入任意字符： ')
i,number,space,other,letter = 0,0,0,0,0
for i in character :
    if ord('a') <= ord(i) <= ord('z') or ord('A') <= ord(i) <= ord('Z'):
        letter += 1
    elif ord('0') <= ord(i) <= ord('9'):
        number += 1
    elif ord(i) == ord(' '):
        space += 1
    else:
        other += 1
print("字母个数为：",letter,'t',"数字个数为：",number,'t',"空格个数为：",space,'t',"其他字符个数为：",other)

结果如下：
