Python math - dist() Function

The Python math.dist() function returns the Euclidean distance between two points p and q, each given as a sequence (or iterable) of coordinates. The two points must have the same dimension. Mathematically, it is equivalent to:

math.dist(p, q) = sqrt(sum((px - qx)**2.0 for px, qx in zip(p, q)))

Syntax

#New in version 3.8
math.dist(p, q)

Parameters

Return Value

Returns the Euclidean distance between two points p and q.

Example: Distance between 2-D points

In the example below, dist() function returns Euclidean distance between two given points.

import math

p = [0, 0]
q = [3, 4]

print("Distance between p and q: ", math.dist(p, q))

The output of the above code will be:

Distance between p and q:  5.0

Example: Distance between 3-D points

Similarly, the function can be used to find distance between 3-D points.

import math

p = [0, 0, 0]
q = [3, 4, 5]

print("Distance between p and q: ", math.dist(p, q))

The output of the above code will be:

Distance between p and q:  7.0710678118654755
