See the note in https://docs.python.org/3.7/reference/compound_stmts.html#the-for-statement "There is a subtlety when the sequence is being modified by the loop ..." Since your code is mutating the all_fields list as you iterate it, you get the " next item will be skipped " behaviour, which is why the loop is skipping over "password". remove() was never called to remove "password". There is an open issue https://bugs.python.org/issue32767 to clarify the docs about this, but it is not a bug in Python.
