The random module provides functions for generating random numbers and selecting random elements.
random.seed
The random.seed function sets the seed value for the random number generator. This allows you to generate reproducible sequences of random numbers.
Syntax
random.seed(x)Parameters
x: An optional number value used as the seed for the random number generator. If not, it defaults totime.time
Return Value
None.
Example
import random
// Set the random seed to a fixed value
random.seed(1234)
// Generate a random number
print(random.random())
// Generate another random number with the same seed
random.seed(1234)
print(random.random())random.random
The random.random function returns a random number between 0.0 and 1.0.
Syntax
random.random()Return Value
A random number between 0.0 and 1.0.
Example
Here are some examples of how to use the random.random function:
import random
// Generate a random float between 0.0 and 1.0
var random_float = random.random()
print(random_float)random.range
The random.range function returns a random integer within a specified range.
Syntax
random.range(start, stop)
random.range(range)
Parameters
start: The starting value of the range.stop: The ending value of the range.range: A range object.
Return Value
A random integer within the specified range.
Example
Here are some examples of how to use the random.range function:
import random
// Generate a random integer between 0 and 9
var random = random.range(0, 10)
print(random)
// Generate a random number from range
random = random.range(1..11)
print(random)random.choice
The random.choice function selects a random element from a list.
Syntax
random.choice(seq)Parameters
seq: A list of elements to select from.
Return Value
A random element from the list.
Example
import random
// Select a random element from a list of integers
var random = random.choice([1, 2, 3, 4, 5])
print(random)
// Select a random element from a list of strings
random = random.choice(['a', 'b', 'c', 'd', 'e'])
print(random)random.shuffle
The random.shuffle function shuffles the elements of a list in place.
Syntax
random.shuffle(seq)Parameters
seq: A list of elements to shuffle.
Return Value
None. The list is shuffled in place.
Example
import random
// Shuffle a list of integers
var numbers = [1, 2, 3, 4, 5]
random.shuffle(numbers)
print(numbers)
// Shuffle a list of strings
var letters = ['a', 'b', 'c', 'd', 'e']
random.shuffle(letters)
print(letters)
