Timing in python turtle

Question

Hi i want to make fun in python turtle that will measure time from start of program to the moment that user will click on space my code looks like this and i have problem with moment when i calculate the time

import turtle
import time

screen = turtle.Screen()
screen.setup(600,600)
t = turtle.Turtle('turtle')
t.speed(3)
time = time.time()

def prawy():
    t.setheading(0)
    t.fd(50)

def lewo():
    t.setheading(180)
    t.fd(50)

def gora():
    t.setheading(90)
    t.fd(50)

def dol():
    t.setheading(270)
    t.fd(50)

def spac(x):
    print(round(time.time()-x,2))


turtle.listen()

turtle.onkey(prawy, 'Right')
turtle.onkey(lewo, 'Left')
turtle.onkey(gora, 'Up')
turtle.onkey(dol, 'Down')
turtle.onkeypress(spac, 'space')

turtle.mainloop()

i know i have to put the time from begining to my fun but i have no idea how THX for support

Answer 1

As far as I can tell there's no variable with the name x declared in your code.

Furthermore you should not name a variable like a module that you are importing, thus change the variable name of time to t1.

Also change the function spac(x) to:

def spac():
   global t1

   print(round(time.time()-t1,2))

take care

Answer 2

You can't define arbitrary arguments for event handlers -- their argument signatures are defined by turtle, not you. So you need to subtract the global that contains the start of time, not the invalid argument to spac():

from turtle import Screen, Turtle
import time

def prawy():
    turtle.setheading(0)
    turtle.fd(50)

def lewo():
    turtle.setheading(180)
    turtle.fd(50)

def gora():
    turtle.setheading(90)
    turtle.fd(50)

def dol():
    turtle.setheading(270)
    turtle.fd(50)

def spac():
    print(round(time.time() - start, 2))

screen = Screen()
screen.setup(600, 600)

turtle = Turtle('turtle')
turtle.speed('slow')

screen.onkey(prawy, 'Right')
screen.onkey(lewo, 'Left')
screen.onkey(gora, 'Up')
screen.onkey(dol, 'Down')
screen.onkeypress(spac, 'space')

screen.listen()

start = time.time()

screen.mainloop()

Answer 3

You could use a daemon thread that goes through all the code, and you could write the function to print the time as of the press of space bar.

The thread:

import threading
import time
Score=0

def Start_Timer():
    global Score
    time.sleep(1)
    Score=Score+1
Timer=threading.Thread(target=Start_Timer, daemon=True)
Timer.start()

The code that presents the time at the end:

def spac():
    print("{0}".format(Score))

Combine it with your previous code:

import turtle
import time
import threading

Score=0

def Start_Timer():
    global Score
    time.sleep(1)
    Score=Score+1
Timer=threading.Thread(target=Start_Timer, daemon=True)
Timer.start()

def prawy():
    t.setheading(0)
    t.fd(50)

def lewo():
    t.setheading(180)
    t.fd(50)

def gora():
    t.setheading(90)
    t.fd(50)

def dol():
    t.setheading(270)
    t.fd(50)

def spac():
    print("{0}".format(Score))


turtle.listen()

turtle.onkey(prawy, 'Right')
turtle.onkey(lewo, 'Left')
turtle.onkey(gora, 'Up')
turtle.onkey(dol, 'Down')
turtle.onkeypress(spac, 'space')

turtle.mainloop()
