1. 用一行输出所有大(小)写字母,以及数字
1 print([chr(i) for i in range(65, 91)]) # 所有大写字母 2 print([chr(i) for i in range(97, 123)]) # 所有小写字母 3 print([chr(i) for i in range(48, 58)]) # 所有数字 4 5 #################### 6 [‘A‘, ‘B‘, ‘C‘, ‘D‘, ‘E‘, ‘F‘, ‘G‘, ‘H‘, ‘I‘, ‘J‘, ‘K‘, ‘L‘, ‘M‘, ‘N‘, ‘O‘, ‘P‘, ‘Q‘, ‘R‘, ‘S‘, ‘T‘, ‘U‘, ‘V‘, ‘W‘, ‘X‘, ‘Y‘, ‘Z‘] 7 [‘a‘, ‘b‘, ‘c‘, ‘d‘, ‘e‘, ‘f‘, ‘g‘, ‘h‘, ‘i‘, ‘j‘, ‘k‘, ‘l‘, ‘m‘, ‘n‘, ‘o‘, ‘p‘, ‘q‘, ‘r‘, ‘s‘, ‘t‘, ‘u‘, ‘v‘, ‘w‘, ‘x‘, ‘y‘, ‘z‘] 8 [‘0‘, ‘1‘, ‘2‘, ‘3‘, ‘4‘, ‘5‘, ‘6‘, ‘7‘, ‘8‘, ‘9‘]
1 import string # 导入string这个模块 2 print(string.digits) # 输出包含数字0~9的字符串 3 print(string.ascii_letters) # 包含所有字母(大写或小写)的字符串 4 print(string.ascii_lowercase) # 包含所有小写字母的字符串 5 print(string.ascii_uppercase) # 包含所有大写字母的字符串 6 7 8 ############## 9 0123456789 10 abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ 11 abcdefghijklmnopqrstuvwxyz 12 ABCDEFGHIJKLMNOPQRSTUVWXYZ
2. 生成随机验证码
1 import random 2 def get_code(): 3 source = list(‘0123456789‘) 4 for i in range(97, 123): 5 source.append(chr(i)) 6 print(‘‘.join(random.sample(source, 4)))
1 def v_code(): 2 code = ‘‘ 3 for i in range(5): 4 add = random.choice([random.randrange(10), chr(random.randrange(97, 123))]) 5 code += str(add) 6 print(code)
