零基础课后题19
def count(a):alptotal = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
number = '0123456789'
qtzf = '.~!@#$%^&*()-=_+[]{}\|:";<>?,/'
for each in a:
b = a.count(alptotal)
b = a.count(number)
b = a.count(qtzf)
return b
word = input('请输入字符串：')
c = count(word)
for each in c:
print('第',each,'字符串包含',c,'个字幕',c,'个数字',c,'个其他字符')
这个运行报错，求问怎么回事 错误比较多：
1.input无法输入多个字符串
2.str.count得到的是子字符串在字符串中的数量。
我修改的程序：
def count(a):
alptotal = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
number = '0123456789'
qtzf = '.~!@#$%^&*()-=_+[]{}\|:";<>?,/'
b =
for each in a:
if each in alptotal:
b += 1
elif each in number:
b += 1
elif each in qtzf:
b += 1
return b
word = input('请输入字符串：')
c = count(word)
print('字符串包含',c,'个字幕',c,'个数字',c,'个其他字符') def count(*a):
lenth = len(a)
for i in range(length):
letter = 0
space = 0
number = 0
others = 0
alptotal = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
numbers = '0123456789'
qtzf = '.~!@#$%^&*()-=_+[]{}\|:";<>?,/'
for each in a:
letter = a.count(alptotal)
number = a.count(number)
other = a.count(qtzf)
space = a.count(' ')
print('第',i,'字符串包含',letter,'个字母',number,'个数字',space,'个空格',other,'个其他字符'
word = input ('请输入字符串')
count(word) 我改了一下，调用函数怎么老是报错
