本文实例讲述了python计算书页码的统计数字问题，是Python程序设计中一个比较典型的应用实例。分享给大家供大家参考。具体如下：
问题描述：对给定页码n，计算出全部页码中分别用到多少次数字0,1,2,3,4...,9
实例代码如下：
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)
上面这段代码略显臃肿，所以改了下代码。
改后的代码如下：
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 result
print count_num2(13)
本文实例测试运行环境为Python2.7.6
程序输出结果为：
[1, 6, 2, 2, 1, 1, 1, 1, 1, 1]
希望本文所述对大家的Python程序设计有所帮助。
