python - Imported module cannot let me use the function it contains -


i'm using 2010 head first book python, chapter 2. i've created module called nester, contains function print_lol, made program should import nester, create little list, , call function print_lol contained in nester. doesn't work, tho. 

import nester  cast = ["palin", "cleese", "idle", "jones", "gilliam", "and chapman."]  nester.print_lol(cast)

this program, , output:

> traceback (most recent call last):    file "<pyshell#2>", line 1, in <module>    nester.print_lol(cast) attributeerror: module 'nester' has no attribute 'print_lol'

what's wrong that? why happens? code in book, same path, environment paths ok. what's wrong?

here 'nester' code, , works properly.

def print_lol(the_list):  each_item in the_list:     if isinstance(each_item, list):         print_lol(each_item)         else:             print(each_item)

also, nester it's in c:\nester. contains setup.py, nester.py, , installation folders , files: manifest, lib, dist, build.

since import nester didn't throw in error, means script can import nester. try (explicit function import)

from nester import print_lol

if fails, make sure print_lol exist in nester, in there no spelling mistakes.

i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
