问在python中生成一个固定长度的随机字符串列表。

EN

>>> import string
>>> import random
>>> L1 = []
>>> my_chars = string.ascii_lowercase + string.digits #list of alphanumeric characters
>>> while(len(L1)<100): #To keep iterating until len(L1)=100
    s = random.sample(my_chars,3) #Pick a sample(list) of three characters len from chars list
    if not all(t in string.digits for t in s) and not all(t in string.ascii_lowercase for t in s): #Check if these characters are neither only digits nor letters, only mix of both will be allowed
        L1.append(''.join(s)) #concatenate the characters to form the string and add it to list L1


>>> len(L1)
100
>>> L1
