浅谈String模块ascii_letters和digits详解编程语言

本文介绍string模块ascii_letters和digits方法,其中ascii_letters是生成所有字母,从a-z和A-Z,digits是生成所有数字0-9.

示例如下:

In [2]: chars = string.ascii_letters + string.digits 
 
In [3]: print(chars) 
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789

生成所有字母和数字干什么?在哪个场景中会用到呢,举个例子:比如生成激活码(优惠券),激活码一般都是字母和数字组成的,首先要有一个所有字母和数字的字符串,然后随机取出几个字母或数字。

In [3]: import random,string 
In [4]: def rand_str(num, length=7): 
   ...:     f = open('Activation_code.txt', 'w') 
   ...:     for i in range(num): 
   ...:         chars = string.ascii_letters + string.digits 
   ...:         s = [random.choice(chars) for i in range(length)] 
   ...:         f.write('{0}/n'.format(''.join(s))) 
   ...:     f.close() 
   ...: 
   ...: 
   ...: if __name__ == '__main__': 
   ...:     rand_str(200) 
   ...:

生成了一个Activation_code.txt文件,如图:
