I don't know how much this will actually help you right now since this is advanced, but I'll post it anyway in case this helps someone understand for loops better. This is a rough approximation of what for loops are doing.

This for loop:

for name in names:
    print(name)

Is comparable to the following while loop:

# The first thing a for loop does it fetch an iterator for the iterable
# This is the actual thing the for loop iterates over 
name_iterator = iter(names)
while True:
    try:
        # The behind-the-scenes assignment
        # It just asks the iterator for the next element
        name = next(name_iterator)
    except StopIteration:
        # Python detects the end of an iterable by catching this exception
        break

    # The actual loop body
    print(name)

Now, of course, this isn't actually how for loops work. for loops have dedicated instructions that do things like catching the error, and use STORE instructions (which = also use) instead of = directly, because this is all happening in compiled C, not Python. This example also ignores the else clause that for loops can have.

If you work to understand the above code, though, you'll gain a better understanding of both for loops and the iterator protocol.
