#统计一个字符串中数字、字母、其他类型字符的个数
s=input('Please input you string:')
print(s,'is all consisted of alpha?:',s.isalpha())#isalpha function
print(s,'is all consisted of digit?:',s.isdigit())#isdigit function
alphacount=0 #the original sum of alpha
digitcount=0 #the original sum of digit
othercount=0 #the original sum of others
for i in s:
if i.isalpha()==True:
alphacount=alphacount+1
elif i.isdigit()==True:
digitcount=digitcount+1
else:
othercount=othercount+1
print('The total sum of alpha:',alphacount)
print('The total sum of digit:',digitcount)
print('The total sum of others:',othercount)
输出举例:
Please inout you string:123456,,,...@@@$$$Inspiration
'123456,,,...@@@$$$Inspiration' is all consisted of alpha?: False
'123456,,,...@@@$$$Inspiration' is all consisted of digit?: False
The total sum of alpha: 11
The total sum of digit: 6
The total sum of others: 12
