So erstellen Sie Eingabefeld, wenn sonst Anweisung in TKinter
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()
