我正在创建一个Tkinter程序，该程序可以为您生成一个随机密码，并可以将您的登录信息存储到任何网站或以后使用。它会为您生成一个密码，询问您的用户名（注册时使用的用户名）和网站名称（您在其中创建帐户的位置）以便可以存储它。之后，如果您再次登录网站，则可以使用该程序搜索登录信息。我试图添加一个自定义密码功能，该功能存储您自己的自定义密码，而不是存储随机密码。

storeinfo()

custompassb.grid(column=3, row=14)
window.mainloop()
在custompass（）函数中，我尝试将x的值更改为用户的输入，然后启动storeinfo（）函数以将信息保存在.txt文件中，但不会发生。而是存储随机密码。
谢谢
您的storeinfo()方法不存储x，这是您的“随机”密码字符的组合。
给它存储一个参数：
def storeinfo(pw = None):
# store x if no pw was given
if pw is None:
pw = x
with open("LoginInfo.txt", "a") as logininfo:
logininfo.write('%s,%s,%s\n' % (WebSite.get(), UserName.get(), pw)) # save pw
savesuccess = tk.Label(text="Save successful!", fg="Purple")
savesuccess.grid(column=4, row=8)
并且还通过提供要存储的东西适当地调用它。
您还应该更仔细地研究string模块和random模块，以使您的代码更好：
from string import ascii_lowercase, ascii_uppercase, digits
a = random.choice(ascii_lowercase)
b = random.choice(ascii_uppercase)
c = random.choice(digits)
# etc. There are other constants for other kinds of things
[从安全的角度来看，将每个第n个字符限制为仅一种输入，这会降低密码的质量，但我想目前它只是一个“我自己”项目。
您可以做类似的事情：
随机导入从字符串导入ascii_lowercase，ascii_uppercase，数字
a = random.choice(ascii_lowercase)
b = random.choice(ascii_uppercase)
c = random.choice(digits)
print(a+b+c)
# or use loops of "sources" and combine them like so
source = [ascii_lowercase, ascii_uppercase, digits, digits, ascii_uppercase, ascii_uppercase]
pw = ''.join( random.choice(w) for w in source )
print(pw)
输出：
