How to build a programme that creates files automatically in python?

Question

Hi. I have a project for my programming class and we have to create a programme for diabetic users. In order to do this,my teacher explained that we needed to create a way for the programme to recognize if a user exists or not and if doesn't exist then we need to create a new file that will save the users information to use later. Please!!! I really need help!!!!

I have programm only for 1 user but i hope you can make this better
try:
f=open("test.txt") #open file test.txt
login=f.readline(1) #read 1 line
password=f.readline(2) # read 2 line
except FileNotFoundError:
f=open("test.txt","w") #open file in write mode
login=input("Enter you login: ")+"\n"
password=input("Enter you password: ")
f.write(login)
f.write(password)
print("You login is "+login+" You password is"+password) #print login and password
