Data is in and not in the file at the same time

[Arvydas_Kromelis]

Hello everyone!

At the moment I'm working on a simple Regiter/Login project which uses text file to store all the data.

username=input("Please enter your username: ")
    with open("Data.txt", "r") as DataFile:
        for i,line in enumerate(DataFile):
            if username in line:
                print("Found the user in line:",i)
                data=line.split()
                password=data[1]
                print(password)
        if username not in DataFile:
            print("Username ",username," not found!")

I get no error messages, but the problem is that both if statements are correct- at the same time username is and not in the file. Any help would be appreciated.


The output:

Please enter your username: Jeff
Found the user in line: 1
123
Username Jeff not found!


DataFile:

Jeff 123
Sandra 753
