Drop Down Menu In Python calling information from files
Question: So I need a drop down menu, where the user picks his/her client, and it
returns information about that client.

lets say i have a file:

    
    
    ["client1", "client2", "client3"]
    

and I have this code:

    
    
    from tkinter import *
    
    master = Tk()
    
    with open('ubclientlistvars.txt', 'r') as clients:
        clients = (clients.readlines())
    
    
    variable = StringVar(master)
    variable.set("Choose Client")
    
    w = OptionMenu(master, variable, clients)
    w.pack()
    
    mainloop()
    

how would I draw the clients from the file into the drop down menu? When I run
this code, i get these two options: `Choose Client` and `{["client1",
"client2", "client3"]}`


Answer: You need to actually parse that file. If the file contents are what you
posted, then `readlines()` is just returning a single line of text. It does
not magically convert the file contents into a Python object. Suppose the file
was:

    
    
    client1
    client2
    client3
    

Then you could use something like `clients = [i.strip() for i in
f.readlines()]` to get a proper list of clients and can pass them to
`OptionMenu`:

    
    
    w = OptionMenu(master, variable, *clients)
    

If you cannot change the file format then you will need to clean up the input
before displaying it...

    
    
    import re
    data = f.read()  # ["client1", "client2", "client3"]
    data = re.sub('["\[\]]', '', data)  # remove the ", [, and ] characters
    clients = data.split(',')  # split the list of clients on the comma
