Doubt regarding a snippet of code

#1

I’m not able to drag and drop images on Chrome for Mac, so, I’ll share the snippet of code.

users = {“Harry”: “Password”,
“Mark”: “Code”}

def login(username,password):

if username in users and users[username] == password:

print(“Hello World”)

else:

print(“Not Authenticated”)

Could you please help me with the line:

if username in users and users[username] == password ?

I don’t understand how ‘username’ connects to the dictionary ‘users’.
Is the function argument ‘username’ used as a key from the dictionary which equates to the argument ‘password’?

Hello @alankarms99_82ff291312452614,
In this program you created dictionary users wherein the key is your username corresponding to it the value is the password for that username. Now you create a function login in which you pass the username and password.
if username in users and users[username] == password ? This line of code checks whether the password entered by the corresponding username is as we inserted in dictionary users.
