Python If Statement question login system easy

The first thing to do is write "1" and then enter username and password. After that, the max number of account is 1 and you can then use the "2" to login. First time asking a question so I am sorry if this is like a dumb question or something. My code is as following:

Code:

print("Type 1 for Create user. Type 2 for login")
Choice = input("Number here: ")

if Choice == ("1"):
print("Welcome to the Create a user interface")
Username = input("Username: ")
Password = input("Password: ")

if Password.count("!") > 0:
   print("Not valid - no special characters!")
else:
  file = open("account.txt", "w")
  file.write(Username)
  file.write("\n")
  file.write(Password)
  file.close()
elif Choice == ("2"):


print("Welcome, please type your Username and Password")
Loginu = input("Write username here: ")
Loginp = input("Write password here: ")
file = open("account.txt", "r")
first_line = file.readline()
if Loginu == first_line:
print("you're logged in")
else:
print("fail")

It's very basic and so on. What I don't understand is why the if Loginu == first_line can't read the first_line variable... It just jumps directly to else:

I hope it helps and I know my code is very basic lol.
