設計一個函數，統計任意一串字符串中數字字符的個數
def numCount():

count = 0

str = raw_input('please input something:')

for i in str:

    if i.isdigit():

        count+=1

print count

numCount()

2，設計函數，統計任意一串字符串中每一個字母的個數，不區分大小寫

import string

def lettersCount():

list1=[]

str = raw_input('please input something:')

for i in str:

    if i.isalpha():

        list1.append(i.lower())

for j in string.lowercase:

    n = list1.count(j)

    if not n:

        continue

    else:

        print '%s 的個數爲%s' %(j,n)

lettersCount()

一、設計一個函數，統計任意一串字符串中數字字符的個數

#!/usr/bin/env python

str1 = raw_input("請輸入字符: ")

def iCount(s):

Count = 0

for i in s:

    if i.isdigit():

        Count += 1

    else:

        pass

print "數字=%d" % (Count)

if name == 'main':

iCount(str)

習題

1. 設計一個函數，統計任意一串字符串中數字字符的個數

例如：

"adfdfjv1jl;2jlk1j2" 數字個數爲3個

list1 = []

aa = raw_input("pls input sth: ")

for i in aa:

if i in "0123456789":

    list1.append(i)

print "the input number is {}".format(len(list1))

2. 設計函數，統計任意一串字符串中每一個字母的個數，不區分大小寫

例如：

"aaabbbcccaae111"

a 5個

b 3個

c 3個

e 1個

list1 = []

list2 = {}

aa = raw_input("pls input sth: ")

for i in aa:

if i.isalpha():

    list1.append(i)

for i in list1:

list2 = list1.count(i)

for k,v in list2.iteritems():

print " total this character {} is {}".format(k,v)
