Question

我想为什么当我尝试将令牌保存到保存时总是保存第一个令牌

#!/usr/bin/python
import random
import string

count = 1
while count <= 5:
    t = string.ascii_lowercase + string.ascii_uppercase + string.digits + string.punctuation
    key = str(''.join(random.sample(t,33)))
    with open('keys','w') as keys:
        keys.write(key)
    count += 1

Answer 1

#!/usr/bin/python
import random
import string

count = 1
with open('keys','w') as keys:
    while count <= 5:
       t = string.ascii_lowercase + string.ascii_uppercase + string.digits + string.punctuation
       key = str(''.join(random.sample(t,33)))
       keys.write(key)
       count += 1

Answer 2

您需要附加文件而不是每次都写入文件，即在open中使用'a'代替-w作为-

#!/usr/bin/python
import random
import string

count = 1
while count <= 5:
    t = string.ascii_lowercase + string.ascii_uppercase + string.digits + string.punctuation
    key = str(''.join(random.sample(t,33)))
    with open('keys','a') as keys:
        keys.write(key)
    count += 1

您可能还需要在每个键之后添加换行符。

始终保存第一个

不，您的代码不会保存第一个密钥，而是保存最后一个生成的密钥。

写入文件，然后保存一个
