Random module

import random

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

randomFloat = random.random() * 5
print(randomFloat)

love_score = random.randint(1, 100)
print(f"Your love score is {love_score}")

List

list data structure

fruits = [item1, item2]

states_of_america = ["Delaware", "Pennsylvania"]
print(states_of_america[0]) 
#output
Delaware

the order is determined by the order in the list.
typing zero as the index of the piece of data.
programmers start continuing from zero.

states_of_america = "Pencilvania"
#alter any item inside the list. 
#easily using this kind of syntax. 

states_of_america.append()
#will add a single item to the end of the list. 

append와 extend의 차이
append() 는 object 를 맨뒤에 추가
extend() 는 literable 객체(리스트, 튜플, 딕셔너리 등)의 엘레먼트를 list에 appending 하는 것

using str.split(',')
directly convert it into a list by seperating out the commas using str.split()

str_inp = "Hello, from, AskPython"
op = str_inp.split(",")
print(op)

#output
['Hello', 'from', 'AskPython']
#the words that are divided by this split charater, which is the comma.

Banker Roulette - who will pay the bill?

import random

names_string = input("Give me everybody's names, separated by a comma. ")
names = names_string.split(", ")

#내가 쓴 답
name = random.randint(0, len(names) - 1)
who_pay_bill = names[name]
print(f"{who_pay_bill} is going to buy the meal today!")

#답안
num_items = len(names)

random_choice = random.randint(0, num_items - 1)
person_who_will_pay = names[random_choice]
print(person_who_will_pay + "is going to buy the meal today."
#num_items로 입력하면 error 발생하므로 꼭 num_items - 1로 입력해야 한다. 

random.choice()사용하는 법
a list by writing random.choice, and it will actually pick an item from that list.

person_who_will_pay = random.choice(names)
print(person_who_will_pay + "is going to buy the meal today.")

Dirty dozen foods

dirty_dozen = ["strawberries", "spinach", "kale", "nectarines", "apple", "grapes", "peaches", "cherries", "pears", "tomatoes", "celery", "potatoes"]

fruits = ["strawberries", "nectarines", "apple", "grapes", "peaches", "cherries", "pears"]
vegetables = ["spinach", "kale", "tomatoes", "celery", "potatoes"]

dirty_dozen = [fruits, vegetables]
#dirty_dozen = [["strawberries", "nectarines", "apple", "grapes", "peaches", "cherries", "pears"], ["spinach", "kale", "tomatoes", "celery", "potatoes"]]

Treasure map

row1 = ["⬜️","⬜️","⬜️"]
row2 = ["⬜️","⬜️","⬜️"]
row3 = ["⬜️","⬜️","⬜️"]
map = [row1, row2, row3]
print(f"{row1}\n{row2}\n{row3}")
position = input("Where do you want to put the treasure? ")

first = int(position[0]) - 1
second = int(position[1]) - 1

selected_row = map[vertical - 1]
selected_row[horizonal - 1] = "x"
#map[[int(second)], [int(first)]] = "x" 과 같이 쓸 수도 있음


print(f"{row1}\n{row2}\n{row3}")

####### Debugging challenge: #########
#Try running this code and type 5.
#It will give you an IndexError and point to line 32 as the issue.
#But on line 38 we are trying to prevent a crash by detecting
#any numbers great than or equal to 3 or less than 0.
#So what's going on?
#Can you debug the code and fix it?
