Use subprocess.check_output instead of os.system:

from tkinter import *
from subprocess import check_output, CalledProcessError

root = Tk()

text1 = Text(root)
text1.pack()

def command():
    try:
        res = check_output(['python', 'helloworld.py'])
        text1.insert(END, res.decode())
    except CalledProcessError:
        print("File not found")

Button(root, text="Hello", command=command).pack()

root.mainloop()
