Token generator Programming

Analysis:

import randomrandom.choice(‘acfhjlio‘)   #随机选择一个字符

‘f‘

str_list=[‘a‘,‘b‘,‘c‘,‘d‘,‘e‘,‘2‘,‘3‘]s = ""s.join(str_list)    #把列表中的字符串连接到s内，连接一起的意思

‘abcde23‘

s = ""for i in range(5):    s = random.choice(‘adfjlui‘)    print(s)

import stringstring.ascii_lowercase     #表示26个小写字母

‘abcdefghijklmnopqrstuvwxyz‘

string.ascii_uppercase     #表示26个大写字母

‘ABCDEFGHIJKLMNOPQRSTUVWXYZ‘

string.ascii_letters      #表示所有字母

‘abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ‘

Instance:

import stringimport randomstr_from = string.ascii_letters + string.digitscount = 10tokens = []for i in range(count):    s = random.choice(str_from)    print(s)    tokens.append(s)"".join(tokens)

Tokens Generator simplifies programming

Analysis:

[x for x in range(8)]

[0, 1, 2, 3, 4, 5, 6, 7]

[ random.choice(string.ascii_letters + string.digits) for x in range(5)]  #x被放弃的变量，只是占位，使random循环5次

[‘K‘, ‘2‘, ‘8‘, ‘a‘, ‘0‘]

[ random.choice(string.ascii_letters + string.digits) for _ in range(5)]

[‘u‘, ‘6‘, ‘W‘, ‘v‘, ‘j‘]

Instance:

import stringimport randomcount = 8str_from = string.ascii_letters + string.digitstonkens = [ random.choice(str_from) for _ in range(count)]"".join(tokens)
