accept?
Two

in Python?
Generates a random integer within a range with a specified step value
What type of distribution does the random.randint()
method use?
Uniform distribution
In the code snippet provided, what will be the range of the random number generated by random.randint(low=5, high=15)
?
5 to 15 (inclusive)
When using random.randint()
to generate random numbers, which statement is true?
All numbers within the specified range have an equal chance of being selected
Study Notes
import random
print(random.randint(low=5, high=15))
This Python code uses the random.randint()
method from the built-in random
module to generate a random integer within the specified range. The randint()
function takes two parameters: low
and high
, which define the range of the random number generated.
In this case, we are generating a number between 5 and 15 (inclusive). The output of this code will be a random integer in the range of 5 to 15.
The random.randint()
method selects a random number from a uniform distribution. This means that every number within the specified range has an equal chance of being selected.
The function is especially useful for generating random numbers within a range. It's commonly used in simulation, game development, and data analysis.
Here's an example of how to use random.randint()
to generate random numbers within a range:
import random
for i in range(10):
num = random.randint(low=1, high=20)
print(num)
This code generates 10 random numbers between 1 and 20 (inclusive) and prints each number.
You can also use the random.randrange()
method to generate a random integer within a range. The randrange()
method is similar to randint()
, but it takes three parameters: start
, stop
, and step
.
Here's an example of how to use random.randrange()
:
import random
print(random.randrange(start=5, stop=15, step=10))
This code generates a random number between 5 and 15 (inclusive), but it only generates a single number. To generate multiple random numbers, you can use a loop.
import random
for i in range(10):
num = random.randrange(start=1, stop=21, step=10)
print(num)
This code generates 10 random numbers between 1 and 20 (inclusive), but only every 10th number is printed.
The random.randrange()
method is particularly useful when you want to generate random numbers with a specific interval between each number.
Learn how to generate random integers in Python using the random.randint() method from the built-in random module. Explore the difference between random.randint() and random.randrange() functions, and understand how to specify ranges for generating random numbers.
