If you need to destructively iterate through a dictionary in Python, then .popitem() can do the trick for you: Python >>> likes = {"color": "blue", "fruit": "apple", "pet": "dog"} >>> while True: ... try: ... print(f"Dictionary length: {len(likes)}") ... item ...
Method 2: Write list to file in using Write function in Python Now let’s see another way to save list to file in Python. We are going to use the Write() function. The write() function takes string as the argument. So, we’ll be using the for loop again to iterate on each eleme...
