Problems with reading and writing to text files in python

Question

I am trying to take an input and write the input to a text file to keep it stored. However, I can't seem to get the user input written over to the text file. Here is my code:

SaveUsername = open(r"C:\Users\Ty\Desktop\Login_sys\SaveUsername.txt","w+")
SavePassword = open(r"C:\Users\Ty\Desktop\Login_sys\SavePassword.txt","w+")
NewUsername = input("Please enter a username: ")
NewPassword = input("Please enter a password: ")
SaveUsername.write(NewUsername)
print (SaveUsername.readline())
SavePassword.write(NewPassword)
print (SavePassword.readline())

I am printing the readline to see if the code gets written and it never does. Please help, thanks.

Answer 1

First of all, you should close the file after you write to it before reading the changes. You should also use with open(...) as it is a better practice (for multiple reasons). Here is the code you should use:

with open(r"C:\Users\Ty\Desktop\Login_sys\SaveUsername.txt", "w") as SaveUsername:
    NewUsername = input("Please enter a username: ")
    SaveUsername.write(NewUsername)

with open(r"C:\Users\Ty\Desktop\Login_sys\SavePassword.txt", "w") as SavePassword:
    NewPassword = input("Please enter a password: ")
    SavePassword.write(NewPassword)

with open(r"C:\Users\Ty\Desktop\Login_sys\SaveUsername.txt", "r") as SaveUsername:
    print(SavePassword.readline())

with open(r"C:\Users\Ty\Desktop\Login_sys\SavePassword.txt", "r") as SavePassword:
    print(SavePassword.readline())

Answer 2

Close a file & open for reading before reading it.

Answer 3

Try This

with open(r"SaveUsername.txt","w+") as SaveUsername:
    NewUsername = input("Please enter a username: ")
    SaveUsername.write(NewUsername)

with open(r"SavePassword.txt","w+") as SavePassword:
    NewPassword = input("Please enter a password: ")
    SavePassword.write(NewPassword)


with open(r"SaveUsername.txt" as SaveUsername:
    print (SaveUsername.readline())

with open(r"SavePassword.txt") as SavePassword:
    print (SavePassword.readline())
