turtle.distance() function in Python

The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. Because it uses tkinter for the underlying graphics, it needs a version of Python installed with Tk support.

turtle.distance()

This method is used to return the distance from the turtle to (x,y) in turtle step units. 

Syntax : turtle.distance(x, y=None) 

Parameters:

x: x coordinate of Vector 2DVec. 

y: y coordinate of Vector 2DVec.

This method can be called in different formats as given below :

distance(x, y) # two coordinates

distance((x, y)) # a pair (tuple) of coordinates

distance(vec) # e.g. as returned by pos()

distance(mypen) # where mypen is another turtle

Below is the implementation of the above method with some examples :

Example 1 :

Python3

# importing package
import turtle

# print the distance
# before any motion
print(turtle.distance())

# forward turtle by 100
turtle.forward(100)

# print the distance
# after a motion
print(turtle.distance())

Output :

0.0
100.0

Example 2 :

Python3

# importing package
import turtle

# print distance (default)
print(turtle.distance())

for i in range(4):

    # draw one quadrant
    turtle.circle(50,90)

    # print distance
    print(turtle.distance())

Output :

0.0
70.7106781187
100.0
70.7106781187
1.41063873243e-14 

Example 3:

Python3

# importing package
import turtle

# print distance with arguments
# in different formats
print(turtle.distance(3,4))
print(turtle.distance((3,4)))
print(turtle.distance((30.0,40.0)))

Output :

5.0
5.0
50.0
