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.
