Code Not Compiling- Unable to figure out Issue - python-3.x

Question

I have been stumped on this for days now and I can seem to figure out what the problem is. I am able to run all of it fine except when I select option 1 on the console menu. I will be able to make through the first inputs and then I get an error every time. Also for some reason when another option is selected, it does not jump to that option, it just starts going the password generator code instead. Any help would be appreciated. Still fairly new to all this.
