Window Not Appearing

[MGallo]

For some reason, everything on this works except for MainWindow(). It adds the person to the tempfile, but the MainWindow never pops up. I get no errors, it just won't show me the window :/

It looks like you are using MainWindow before you define it? Also, not sure if this applies, but I think you might have to use Toplevel() instead of Tk() when making another window.
Side note: since you have a lot of code, it might be helpful to add some comments to it

[MGallo]

Is this better? I don't think I called MainWindow() before I defined it, but I think you made that mistake cause I posted the code wrong XD (sorry about that) But yeah it just won't open the MainWindow() function, although it shows no errors. :/
Thanks for the help!

you are trying to use grid and pack on the same frame (mainframe) that's a no no.
Remove either the grid or the pack.
One but not both.
Also, change the def for mainwindow to:

def MainWindow(creds)
# and then call like:
MainWindow('tempfile.temp')

also it's better to use naming like main_window (PEP8) rather than camel case

All of your suggestions helped and made it work! Thanks!

I was also wondering one more thing though, do you have any recommendations on how to be able to add more people in my program? If not it's fine :P
Thanks!

when you open your save file, use mode 'a' (append)
Now you can just add new people to the end of the file.
It would be even better to use json format, which you can load,
append in memory, and rewrite when done.
There are some good tutorials on json
Here's one I like: https://pymotw.com/3/json/

I'll play with your code a bit and get back soon

I'm calling it quits for the day.
Almost done with changes, pick up later

Ok,

Hope you don't mind, but I kind of got carried away with this.
All seems to work, except for some reason the entry portion is sitting in the
middle of the right frame, rather than at top.
I also didn't clear entry out after a new person was entered.
I'll leave that for you to finish.
Here's what I did:

please PM very sparingly.
It's OK to share with the forum.

As to your questions:

• delete person -- I'll add this for you, but may not get to it for a while.
       basically, to delete from a dictionary, you use del dictname[key]
