Random? randint? choice? what.. All you need 2 know about the random module

Now now now. I have been doing topics on how to use modules and some random stuff. I actually felt like I should not dive into the basics of the random module since you can learn it pretty easily but I just feel like someone, atleast 1 person, still does not understand how it works.

To use the random library in Python, you usually start by importing it using the import keyword like this:

import random

Once you’ve imported the random library, you can use its various functions to generate random numbers, shuffle sequences, and make random choices.

Here’s an example of how to use the random library to generate a random number between 1 and 10:

import random

random_number = random.randint(1, 10)

print(random_number)

This will output a random number between 1 and 10 (inclusive). You can use other functions like random.choice() to make random choices from a list, and random.shuffle() to shuffle the elements of a list in a random order.

Here’s how you can use random.shuffle and random.choice to work with a list of fruits:

import random

fruits = ["apple", "banana", "cherry", "kiwi", "orange", "pear"]

random.shuffle(fruits)

print(fruits) # Output: ['kiwi', 'cherry', 'banana', 'pear', 'orange', 'apple']

random_fruit = random.choice(fruits)

print(random_fruit) # Output: e.g. 'pear'

random.shuffle takes a sequence (a list in this case) and reorders its elements randomly. In the above code, fruits is shuffled in place. After shuffling, the order of the elements in fruits is randomized.

random.choice takes a sequence and returns a random element from it. In the above code, random_fruit is assigned a value that is a random element of fruits.

Note that random.shuffle shuffles a sequence in place, which means that the original list is modified. If you want to shuffle a copy of the list instead, you can make a copy first:

import random

fruits = ["apple", "banana", "cherry", "kiwi", "orange", "pear"]

shuffled_fruits = fruits.copy()

random.shuffle(shuffled_fruits)

print(fruits) # Output: ['apple', 'banana', 'cherry', 'kiwi', 'orange', 'pear']

print(shuffled_fruits) # Output: e.g. ['pear', 'cherry', 'kiwi', 'banana', 'orange', 'apple']

In this code, the copy method is used to create a separate copy of the fruits list, which can be shuffled independently of the original.

That is the basics on how to use the random module

You can also use random.uniform to get a random float

Well yes. But This is just for the basics of the random module. I won’t dive deeper into the module. Literally if I dive deeper some would probably not understand but okay.

And I am quite sleepy its 2:43 am here rn so ima head to sleep

How? How would people not understand? It does the same thing as randint except with floats instead of integers

There’s way more functionality to random, so I’d look at the docs a bit and see if anything stands out as useful. Like you said, you seem to be doing a deep dive into modules, which is great! I’d link some sort of documentation in your future posts if people want to find out more.
