Trying to make a simple clock work is harder then I thought

Question

I keep having problems with the syntax error in pydroid 3 this is the code I am using but it simply just keeps giving me syntax errors and won't run it I'm pretty new to python and don't know how to fix this
from tkinter import *
from time import strftime

def time():
clock=strftime('%H:%M:%S:%P')
label.configure(text=clock)
label.after(1000, time)

root=Tk()
Label=Label(root,fg="red",bg="green")
Label.pack()
time()
root.mainloop()

Answer 1
