本文實例講述了python計算書頁碼的統計數字問題，是Python程序設計中一個比較典型的應用實例。分享給大家供大家參考。具體如下：

問題描述：對給定頁碼n，計算出全部頁碼中分別用到多少次數字0,1,2,3,4...,9

實例代碼如下：

def count_num1(page_num):   num_zero = 0   num_one = 0   num_two = 0   num_three = 0   num_four = 0   num_five = 0   num_six = 0   num_seven = 0   num_eight = 0   num_nine = 0   page_list = range(1,page_num + 1)   for page in page_list:     page = str(page)     num_zero += page.count('0')     num_one += page.count('1')     num_two += page.count('2')     num_three += page.count('3')     num_four += page.count('4')     num_five += page.count('5')     num_six += page.count('6')     num_seven += page.count('7')     num_eight += page.count('8')     num_nine += page.count('9')   result = [num_zero,num_one,num_two,num_three,num_four,num_five,num_six,num_seven,num_eight,num_nine]   return result  print count_num1(13) 

上面這段代碼略顯臃腫，所以改了下代碼。

改后的代碼如下：

def count_num2(page_num):   page_list = range(1,page_num + 1)   result = [0 for i in range(10)]   for page in page_list:     page = str(page)     for i in range(10):       temp = page.count(str(i))       result[i] += temp   return resultprint count_num2(13)

本文實例測試運行環境為Python2.7.6

程序輸出結果為：

[1, 6, 2, 2, 1, 1, 1, 1, 1, 1]

希望本文所述對大家的Python程序設計有所幫助。
