Getting Tkinter.entry Input Into If/else Statements

Here is my current code, which I have changed multiple times using different answers of different answered questions on here. The problem is I am trying to find a way to get the co

Solution 1:

You can convert string to lower case and compare only with "screen"

if entry.get().strip().lower() == "screen":

I use strip() to remove spaces at the both ends of string because sometimes user can enter extra spaces ie. " screen "

Or you can use in

if entry.get().strip() in ("Screen", "screen", "Monitor", "monitor"):

 if entry.get().strip().lower() in ("screen", "monitor"):

because it is shorter then

if entry.get().strip() == "Screen"or entry.get().strip() == "screen"or entry.get().strip() == "Monitor"or entry.get().strip() == "monitor":

 if entry.get().strip().lower() == "screen"or entry.get().strip().lower() == "monitor":

You can also use strip().lower() before if/else

 answer = entry.get().strip().lower()

 if answer in ("screen", "monitor"):
     # ...elif answer in ("mouse", "trackball"):
     # ...elif answer == "keyboard":
     # ...

Working example

import tkinter as tk

# --- functions ---# `bind` sends `event` to function so it has to receive it# `command=` doesn't sends `event` so it need some default value - ie. Nonedefon_button(event=None): 

    answer = entry.get().strip().lower()

    if answer in ("screen", "monitor"):
        # change text in existing label
        label['text'] = "Your {} is dirty. I can't see you.".format(answer)

    elif answer in ("mouse", "trackball"):
        label['text'] = "Your {} is too slow for me".format(answer)

    else:
        label['text'] = "{0}? What is {0}?".format(answer)

# --- main ---

root = tk.Tk()
root.geometry("300x300")
root.title("Try code")

entry = tk.Entry(root)
entry.pack()

# run function when in `entry` you press `ENTER` on keyboard 
entry.bind('<Return>', on_button) 

button = tk.Button(root, text="Enter", command=on_button)
button.pack()

label = tk.Label(root)
label.pack()

# activate `entry` so you don't have to click in `entry` to start typing
entry.focus() 

root.mainloop()

Solution 2:

Your Boolean expression in your if statement was not right.You have to explicitly tell Python what exactly you want to do:

import tkinter

root = tkinter.Tk()
root.geometry("300x300")
root.title("Try code")

entry = tkinter.Entry(root)
entry.pack()
print(entry.get())
def on_button():
    if entry.get() == "Screen"or entry.get() == "screen": #corrected
        slabel = tkinter.Label(root, text="Screen was entered")
        slabel.pack()
    else:
        tlabel = tkinter.Label(root, text="")
        tlabel.pack()

button = tkinter.Button(root, text="Enter", command=on_button)
button.pack()

root.mainloop()

And now it works:
