# Python: How to find the distance between two points in Python?

## Python Basic: Exercise-40 with Solution

Write a Python program to calculate the distance between the points (x1, y1) and (x2, y2).

**Pictorial Presentation:**

**Sample Solution:**

**Python Code:**

```
# Import the math module to use the square root function.
import math
# Define the coordinates of the first point (p1) as a list.
p1 = [4, 0]
# Define the coordinates of the second point (p2) as a list.
p2 = [6, 6]
# Calculate the distance between the two points using the distance formula.
# The formula computes the Euclidean distance in a 2D space.
distance = math.sqrt(((p1[0] - p2[0]) ** 2) + ((p1[1] - p2[1]) ** 2))
# Print the calculated distance.
print(distance)
```

Sample Output:

6.324555320336759

**Explanation:**

The said code calculates the Euclidean distance between two points in a 2-dimensional coordinate system.

- It starts by importing the "math" module which is used to calculate the square root of the given expression.
- Then it defines two variables p1 and p2 which are lists containing the x and y coordinates of two points. In this case, the first point is at coordinates (4, 0) and the second point is at coordinates (6, 6).
- The variable "distance" is defined and assigned the value of the Euclidean distance between the two points.
- The final distance is then printed using the print() function.

The final output will be 6.324555320336759 which is the distance between the two points (4,0) and (6,6).
