保存.env

Question

我正在制作用户名和密码python，我想知道我的.env如何保存它的内容。请将经过编辑的代码放在注释中，并描述您更改的内容。谢谢!

守则如下：

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')

修改os.environ。见这里。

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

从env读取

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