Solution: The working Yes/No control and EnterBox [ID:248] (7/17)

in series: Python 101 - easygui and csv

Here we have the working solution to the exercise from the previous episode. See my answer for talking to the user and writing some more logic.

Created May 2007, running time 2 minutes

import easygui # DONE the TODO for the import statement

# use easygui's enterbox to ask for the name from the user
name=easygui.enterbox("Please enter your name")

# use easygui's yes/no box to ask a Yes/No question
yesNo = easygui.ynbox(message = "Is "+name+" your name?")

# if "Yes" then we print the name back out
# with easygui a 'Yes' answer is represented as an Integer 1
# which is equivalent to True for Boolean logic
if yesNo == 1: # if 1 then this statement becomes True
    print "Yes "+name+" is your name"
# if you press No then print another message
# TIP Just as 1 is True, a 0 represents False
# so you can copy the section of code above and make
# one logic change and rewrite the print message
if yesNo == 0:
    print "No " + name + " is not your name you silly-billy!"

Is it proper to use elif on the end? as such:

elif yesNo == 0:

Or is that a bad coding habit within PY?


yep, same here. had to use the new "msg" instead of "message" on the yesNo line.

great tutorial so far, Ian. i discovered this site via the Ubuntu UK podcast. you seem to be the rare person who knows how to program *and* how to teach. not many have this combination of skills. glad to be here.


worked well for me

you may cover this in the future videos, however, what about using else within if statements, saves time and code

if yesNo == 1: # if 1 then this statement becomes True

print "Yes "+name+" is your name"


print "No, "+name+" is not your name, you silly-billy!"

still enjoying the CBT though.

keep it up

Possibly the author of easygui has changed the api? Thanks for the fix, certainly 'message' used to be the right way to do it.



the supplied source code:

# use easygui's yes/no box to ask a Yes/No question

yesNo = easygui.ynbox(message = "Is "+name+" your name?")

this didn't work for me. The Easygui reference for ynbox:

ynbox(msg='Shall I continue?', title=' ', choices=('Yes', 'No'), image=None)

I changed message to msg and everything's working.

Review of Solution: The working Yes/No control and EnterBox

The exercise format is great. I did find that if I use message="Is ..." that I got the following

an unexpected keyword argument 'message'. I left out message= and it worked great.

Work fine for me, I also did a variance by using this line :

easygui.msgbox(message='So '+name+' is your name', title='Your name', buttonMessage='OK')

in order to get a message box at the end.

Hi Ryan, it is great to hear that the challenges and GUI components are useful to you.


Yeah, nice overview of the Y/N and EnterBox. I can see where this is going, very interactive use of the more advanced python functionality! Excellent video.

Nice quick overview of the Enter Box/ Yes/NO box using easygui. These are two of the most common dialogs used when designing GUI's so this basic overview is necessary.

Yes, that was a bug with our source-code tab :-( It is fixed now, though every entry has to have a leading blank line (which doesn't affect the Python at all).

This is the first time we're using the new Source tab, it does look rather pretty don't you think?


The source code above has leading spaces on line number 1 (wrongly, i think); the source code in the video not. maybe some mixup at the upload of the file ?

Showmedo is a peer-produced video-tutorials and screencasts site for free and open-source software (FOSS)- with the exception of some club videos, the large majority are free to watch and download.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Ian
