python .env 更改保存

Question

我正在创建用户名和密码 python，我想知道如何让我的 .env 保存它的内容。请将编辑后的代码放在评论中，并描述您所做的更改。谢谢！

代码如下：

import os

os.environ['USER'] = 'admin'
os.environ['PASSWORD'] = 'admin'

print('Please Log In. admin Is The Defalt User And Password')
print('Username:')
inputed_username = input()

logged_username = os.getenv('USER')

if  inputed_username == logged_username :
  logged_password = os.environ.get('PASSWORD')
  print('Password:')
  inputed_password = input()
  if inputed_password == logged_password :
    print('Welcome ' + inputed_username + '!')
    while True :
      print('What Do You Want To Do?')
      print('''
    1: Change Username
    2: Change Password
    3: Log Out
      ''')
      ch1 = input()
      if ch1 == '1' :
        print('What Do You Want Your New Username To Be?')
        new_username = input()
        os.environ['USER'] = new_username
        
      if ch1 == '2' :
        print('What Do You Want Your New Password To Be?')
        new_password = input()
        os.environ['PASSWORD'] = new_password
        
      if ch1 == "3" :
        break
        
        
  else :
      print('WRONG PASSWORD')
else :
  print('WRONG USERNAME')

I am making a username and password python thing and I was wondering how I would have my .env save its contents

修改os.environ。参见 here。

inputed_username = input()
os.environ['USER_NAME'] = inputed_username

从环境读取

value = os.getenv('USER_NAME','admin')  # admin is the default

python .env 更改保存

python .env change saves

python

environment-variables
