I dont get it, thanks for you help.it does delete the flash_cards,txt. but doesn't overwrite it.

if anyone wonders, i code a simple Quizlet programm for exercise.

Answer 1

The issue is here. You are using same name for both the file object and loop variable. When you call f.write(l + "=" + f + "\n") , f is no longer a file object(Because the the loop variable overwritten f into a string object)

with open("./flash_cards.txt", "w+") as :
    for l,  in flash_cards.items():
       f.write(l + "=" + f + "\n")

Answer 2

you have f in your for inside the with

You may choose another variable, and the problem will be removed. As example:

    with open("./flash_cards.txt", "w+") as f:
        for l, value in flash_cards.items():
            f.write(l + "=" + value + "\n")
