Randomization and Python Lists

Do check this Page: Python Random Module Methods

We will explore Generate Random Integers:

randint(a, b):

Returns a random integer between a and b (both inclusive). This also raises an ValueError if a > b.

import random

random_int = random.randint(1,10)
print(random_int)

PS \Python> python .\random_int.py

We can create our own module and import it.

#my_module.py

pi = 3.1415

#random_int.py

import random
import my_module

random_int = random.randint(1,10)
print(random_int)


print(my_module.pi)

Generating Random floating point numbers:

Similar to generating integers, there are functions that generate random floating point sequences.

• random.random() -> Returns the next random floating point number between [0.0 to 1.0)
• random.uniform(a, b) -> Returns a random floating point N such that a <= N <= b if a <= b and b <= N <= a if b < a.
• random.expovariate(lambda) -> Returns a number corresponding to an exponential distribution.
• random.gauss(mu, sigma) -> Returns a number corresponding to a gaussian distribution.

There are similar functions for other distributions, such as Normal Distribution, Gamma Distribution, etc.

import random


random_int = random.randint(1,10)
print(random_int)

random_flot =  random.random()
print(random_flot)

Project 1: Love Score

import random
print("\n")
print("-------Welcome to Love Calculator-------\n")

name1 =  input("What is your name?\n")
name2 =  input("What is their name?\n")

love_score =  random.randint(1, 100)

print(f"Love score of {name1} and {name2} is {love_score}")

>>

-------Welcome to Love Calculator-------

What is your name?
Lisa
What is their name?
Jack
Love score of Lisa and Jack is 34

Project 2: Heads or Tails

import random

random_side =  random.randint(0, 1)

if random_side == 1:
    print ("Heads")
else:
    print("Tails")

>>

PS \Python> python.exe .\heads_tails.py

List :

Check this List : Data Structure

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']
print(fruits[2])
print(fruits[-2])

>>

pear
apple

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']
print(fruits[2])
print(fruits[-2])

fruits[2] =  "Cheery"   #CHNAGE NAME
print(fruits)

>>

pear
apple
['orange', 'apple', 'Cheery', 'banana', 'kiwi', 'apple', 'banana']

You can append it to the list :

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']

fruits.append("Nid")
print(fruits)

>>
['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana', 'Nid']

Extend list:

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']

fruits.extend(["AP", "gy"])
print(fruits)

>>
['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana', 'Nid', 'AP', 'gy']    

To check the length of the list

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']

print(len(fruits))

Project 3: Who Will Pay

names =  input("Enter the names\n")

name_list = names.split(", ")

import random

num_item = len(names)

random_choice = random.randint(0, num_item - 1)
print(names[random_choice])

Nested List

fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']
vegetables = ['Beetroot', 'Carrots', 'Capsicum', 'Ginger', 'Cauliflower']

fridge = [fruits, vegetables]
print(fridge)

>>

[['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana'], ['Beetroot', 'Carrots', 'Capsicum', 'Ginger', 'Cauliflower']]

Project 4: Treasure Map

line1 = [" ", " "," "]
line2 = [" ", " "," "]
line3 = [" ", " "," "]
map = [line1, line2, line3]

print("\nHiding your treasure! X marks the spot.")
print("There are three rows and coloumes\n")


postion = input("Where do you want to put the treasure?")

letter = postion[0].lower()

abc = ["a", "b", "c"] #Possiable entry 

letter_index = abc.index(letter) 
#Checking if in "letter" (we entry), that is  there in the list or not 
#This will give us number

number_index = int(postion[1]) - 1 
#Whatever position we entered, -1 because list stars from [0]

map[number_index][letter_index] = "X"

print(f"{line1}\n{line2}\n{line3}")
   


>>


Hiding your treasure! X marks the spot.
There are three rows and coloumes

Where do you want to put the treasure?B3
[' ', ' ', ' ']
[' ', ' ', ' ']
