Python Random randint() Method with Examples

Python / By

Random randint() Method in Python:

The randint() method returns an integer number representing a randomly chosen element from the specified range.

Note: It is to be noted that randint() method is an alias for randrange(start, stop+1).

Syntax:

random.randint(start, stop)

Parameters

start: This is Required. It is an integer indicating the starting position.

stop: This is Required. It is an integer indicating the position at which to end.

Examples:

Example1:

Input:

Given start value = 4
Given stop value = 12

Output:

The random number between 4 and 12 = 12  (includes both 4 and 12)

Example2:

Input:

Given start value = 40
Given stop value = 45

Output:

The random number between 40 and 45 = 42 (includes both 40 and 45)

Random randint() Method with Examples in Python

Method #1: Using Built-in Functions (Static Input)

Approach:

  • Import random module using the import keyword.
  • Give the number(start value) as static input and store it in a variable.
  • Give the other number(stop value) as static input and store it in another variable.
  • Pass the given start and stop values as the arguments to the random.randint() method to get a random number between the given start and stop values ( both start and stop values are included).
  • Store it in another variable.
  • Print a random number between the given start and stop values.
  • The Exit of the Program.

Below is the implementation:

# Import random module using the import keyword.
import random
# Give the number(start value) as static input and store it in a variable.
gvn_strtval = 4
# Give the other number(stop value) as static input and store it in another variable.
gvn_stopval = 12
# Pass the given start and stop values as the arguments to the random.randint()
# method to get a random number between the given start and stop values.
# ( both start and stop values are included).
# Store it in another variable.
rslt = random.randint(gvn_strtval, gvn_stopval)
# Print a random number between the given start and stop values.
print("The random number between", gvn_strtval, "and", gvn_stopval, "=", rslt)

Output:

The random number between 4 and 12 = 12

Method #2: Using Built-in Functions (User Input)

Approach:

  • Import random module using the import keyword.
  • Give the number(start value) as user input using the int(input()) function and store it in a variable.
  • Give the other number(stop value)  as user input using the int(input()) function and store it in another variable.
  • Pass the given start and stop values as the arguments to the random.randint() method to get a random number between the given start and stop values ( both start and stop values are included).
  • Store it in another variable.
  • Print a random number between the given start and stop values.
  • The Exit of the Program.

Below is the implementation:

# Import random module using the import keyword.
import random
# Give the number(start value) as user input using the int(input()) function and store it in a variable.
gvn_strtval = int(input("Enter some random number = "))
# Give the other number(stop value)  as user input using the int(input()) function 
# and store it in another variable.
gvn_stopval = int(input("Enter some random number = "))
# Pass the given start and stop values as the arguments to the random.randint()
# method to get a random number between the given start and stop values.
# ( both start and stop values are included).
# Store it in another variable.
rslt = random.randint(gvn_strtval, gvn_stopval)
# Print a random number between the given start and stop values.
print("The random number between", gvn_strtval, "and", gvn_stopval, "=", rslt)

Output:

Enter some random number = 40
Enter some random number = 45
The random number between 40 and 45 = 42
