In the previous article, we have discussed Python Program to Find Line Passing Through 2 Points

Given two points of a line (which are the start and endpoints) and the task is to find the midpoint of the given line in python.

**The formula for the midpoint of a line:**

Let the two points of a line are (x1, y2) and (x2, y2).

The formula for midpoint is:

Midpoint = ((x_{1}+x_{2})/2 , (y_{1}+y_{2})/2)

**Examples:**

**Example1:**

**Input:**

Given First Point = ( 3 , 1 ) Given Second Point = ( 4 , 5 )

**Output:**

The Midpoint of the given line is: ( 3 , 3 )

- Python Program for Maximum Area of Quadrilateral

**Example2:**

**Input:**

Given First Point = ( 6 , -2 ) Given Second Point = ( 7, 4 )

**Output:**

The Midpoint of the given line is: ( 6 , 1 )

## Program to Find the Mid-Point of a Line in Python

Below are the ways to find the midpoint of the given line in python:

### Method #1: Using Mathematical Formula (Static Input)

**Approach:**

- Give the first point as static input and store it in two variables.
- Give the second point as static input and store it in another two variables.
- Pass the given two points of a line i.e, a1, a2, b1, b2 as the arguments to the
**Find_Midpoint****()**function. - Create a function to say
**Find_Midpoint()**which takes the given two points of a line i.e, a1, a2, b1, b2 as the arguments, and prints the midpoint of the given line. - Calculate the x coordinate of the midpoint of the given line using the above given mathematical formula and store it in a variable.
- Calculate the y coordinate of the midpoint of the given line using the above given mathematical formula and store it in another variable.
- Print the midpoint of the given line.
- The Exit of the Program.

**Below is the implementation:**

# Create a function to say Find_Midpoint() which takes the given two points of a line i.e, # a1, a2, b1, b2 as the arguments, and prints the midpoint of the given line. def Find_Midpoint(a1, a2, b1, b2): # Calculate the x coordinate of the midpoint of the given line using the above # given mathematical formula and store it in a variable. mid_x_Coordinate = (a1 + a2) // 2 # Calculate the y coordinate of the midpoint of the given line using the above # given mathematical formula and store it in another variable. mid_y_Coordinate = (b1 + b2) // 2 # Print the midpoint of the given line. print("(", mid_x_Coordinate, ",", mid_y_Coordinate, ")") # Give the first point as static input and store it in two variables. a1 = 3 b1 = 1 # Give the second point as static input and store it in another two variables. a2 = 4 b2 = 5 print("The Midpoint of the given line is:") # Pass the given two points of a line i.e, a1, a2, b1, b2 as the arguments to the # Find_Midpoint() function. Find_Midpoint(a1, a2, b1, b2)

**Output:**

The Midpoint of the given line is: ( 3 , 3 )

### Method #2: Using Mathematical Formula (User Input)

**Approach:**

- Give the first point as user input using map(),int(),split() functions and store it in two variables.
- Give the second point as user input using map(),int(),split() functions and store it in two variables.
- Pass the given two points of a line i.e, a1, a2, b1, b2 as the arguments to the
**Find_Midpoint****()**function. - Create a function to say
**Find_Midpoint()**which takes the given two points of a line i.e, a1, a2, b1, b2 as the arguments, and prints the midpoint of the given line. - Calculate the x coordinate of the midpoint of the given line using the above given mathematical formula and store it in a variable.
- Calculate the y coordinate of the midpoint of the given line using the above given mathematical formula and store it in another variable.
- Print the midpoint of the given line.
- The Exit of the Program.

**Below is the implementation:**

# Create a function to say Find_Midpoint() which takes the given two points of a line i.e, # a1, a2, b1, b2 as the arguments, and prints the midpoint of the given line. def Find_Midpoint(a1, a2, b1, b2): # Calculate the x coordinate of the midpoint of the given line using the above # given mathematical formula and store it in a variable. mid_x_Coordinate = (a1 + a2) // 2 # Calculate the y coordinate of the midpoint of the given line using the above # given mathematical formula and store it in another variable. mid_y_Coordinate = (b1 + b2) // 2 # Print the midpoint of the given line. print("(", mid_x_Coordinate, ",", mid_y_Coordinate, ")") # Give the first point as user input using map(),int(),split() functions # and store it in two variables. a1, b1 = map(int, input( 'Enter some random first point values separated by spaces = ').split()) # Give the second point as user input using map(),int(),split() functions # and store it in two variables. a2, b2 = map(int, input( 'Enter some random second point values separated by spaces = ').split()) print("The Midpoint of the given line is:") # Pass the given two points of a line i.e, a1, a2, b1, b2 as the arguments to the # Find_Midpoint() function. Find_Midpoint(a1, a2, b1, b2)

**Output:**

Enter some random first point values separated by spaces = 6 -2 Enter some random second point values separated by spaces = 7 4 The Midpoint of the given line is: ( 6 , 1 )
