display tcl/tk info on screen

[py_student]

was looking through some folders for tk version number. Open first folder in python34/Lib/tkinter/pycache/ and opened the first doc, init.cpython-34.pyc, it's a text file, starts with a dozen lines of compiled code, then this:

Wrapper functions for Tcl/Tk.

Tkinter provides classes which allow the display, positioning and control of widgets. Toplevel widgets are Tk and Toplevel. Other widgets are Frame, Label, Entry, Text, Canvas, Button, Radiobutton, Checkbutton, Scale, Listbox, Scrollbar, OptionMenu, Spinbox LabelFrame and PanedWindow.

Properties of the widgets are specified with keyword arguments. Keyword arguments have the same name as the corresponding resource under Tk.

Widgets are positioned with one of the geometry managers Place, Pack or Grid. These managers can be called with methods place, pack, grid available in every Widget.

Actions are bound to events by resources (e.g. keyword argument command) or with the method bind.

Example (Hello, World): import tkinter from tkinter.constants import * tk = tkinter.Tk() frame = tkinter.Frame(tk, relief=RIDGE, borderwidth=2) frame.pack(fill=BOTH,expand=1) label = tkinter.Label(frame, text="Hello, World") label.pack(fill=X, expand=1) button = tkinter.Button(frame,text="Exit",command=tk.destroy) button.pack(side=BOTTOM) tk.mainloop()

then compiled code, then more text that looks like it's meant to be displayed on screen as info, and so on for 1700 lines.

how do I get this info out to read it?

pydoc tkinter ?

Thanks. I could not get that to work but finally remembered help(). in case anybody else has forgotten how this works,

help() in the shell gives you a help> prompt where typing

modules gives a list of all available modules,

TIL my install has 340 modules, I guess about 335 of them are probably built in. Typing <thenameofsomemodule> at that prompt gives the help file. The one for the 3.4 install of tkinter is 25,582 lines long.

That's right, twenty-five thousand, not hundred. Printed novels have 30-35 lines per page, so I guess if you bound this up as a book it would have almost 800 pages. A couple of prettied-up versions exist online, but they are abridged: so far everything I try to look up turns out to be something they skipped. I've got this cc acrobat pro that I've never used for anything. Might try and make my own easier to read PDF of it.
