I am not able to understand why "password" word is not removed by remove() method

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.
