Python random.choice() Method: Description & Use
The random() is an in-built function of 'random' module in Python, it is used to return a random element from a container like object like lists, string, tuple etc.
Import statement
To use the choice() method, you need to import the random module. Consider the below import statement:
import random
Syntax
Below is the syntax of random.choice() method:
random.choice(container_type_object)
Parameters
Here, container_type_object may a string, list of numbers, list of strings, tuple etc.
Sample Input & Output
The below example demonstrates the working of the random.choice() method with the help of sample input and output.
Input string: "Hello"
Output (May different)
e - first time
H - second time
Input:
random.choice([1, 2, 3, 4, 5, 6])
Output:
A random number from 1 to 6
Examples of Python random.choice() Method
Practice these examples to understand the concept of generating random elements using the random.choice() method.
Example 1: Generate random characters from a string
Given a string, generate and print random characters from it.
# import statement
import random
# defining string
str_var = "Hello!"
# Generating & pritning 3 random
# characters from string 'str_var'
print("Random chars from string: ", str_var)
print(random.choice(str_var))
print(random.choice(str_var))
print(random.choice(str_var))
Output
The output of the above program is:
RUN 1:
Random chars from string: Hello!
!
l
o
RUN 2:
Random chars from string: Hello!
o
l
!
Example 2: Generate random numbers from a list of numbers
Given a list of numbers, generate and print random numbers from it.
# import statement
import random
# defining list of numbers
num_list = [10, 20, 30, 40, 50]
# Generating & pritning 3 random
# numbers from number list 'num_list'
print("Random numbers from num list: ", num_list)
print(random.choice(num_list))
print(random.choice(num_list))
print(random.choice(num_list))
Output
The output of the above program is:
RUN 1:
Random numbers from num list: [10, 20, 30, 40, 50]
20
40
10
RUN 2:
Random numbers from num list: [10, 20, 30, 40, 50]
30
20
20
Example 3: Generate random strings from a list of strings
Given a list of strings, generate and print random strings from it.
# import statement
import random
# defining list of strings
str_list = ["Hello", "Hi", "Bye"]
# Generating & pritning 3 random
# strings from strings list 'str_list'
print("Random strings from strings list: ", str_list)
print(random.choice(str_list))
print(random.choice(str_list))
print(random.choice(str_list))
Output
The output of the above program is:
RUN 1:
Random strings from strings list: ['Hello', 'Hi', 'Bye']
Bye
Hi
Hi
RUN 2:
Random strings from strings list: ['Hello', 'Hi', 'Bye']
Bye
Bye
Hello
