Answer:

square brackets [ ]

Explanation:

In python programming language a list is a data structure type that contains data values which can be of different data types separated by commas and enclosed in a pair of square brackets. in the example below, I have created a list and initialized the values

MyList = [ 2,3,4,5,"David", 2.5, 5.8].

This list contains three different data types integers, float and a string

This code below will produce the output that is attached as an image

MyList = [2,3,4,5,"David"]

print(MyList[0])

print(MyList[1])

print(MyList[2])

print(MyList[3])

print(MyList[4])

Observe that list follow the zero-based indexing

When a programmer creates an abstract data type, he or she can decide what values are acceptable for the data type, as well as w

Vanyuwa [196]

The abstract data type is a type of data type whose behavioural manner is always determined by a set of values and a set of operations.

Explanation:

These data types depend only on extracting the data and hiding the essential background data. That is why it is called an abstract data type.

It will not show how it is implemented, what algorithms are used and how the data is manipulated.

The abstract data type has three types

i)List ADT

ii)Stack ADT

iii)Queue ADT.

This is how an abstract data type works.

Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. T

topjm [15]

Answer:

Explanation:

The following is written in Python. It creates the dictionary as requested and prints it out to the output file as requested using the correct format for various shows with the same number of seasons.The output can be seen in the attached picture below.

mydict = {}

with open("file1.txt", "r") as showFile:

for line in showFile:

cleanString = line.strip()

seasons = 0

try:

seasons = int(cleanString)

print(type(seasons))

except:

pass

if seasons != 0:

showName = showFile.readline()

if seasons in mydict:

mydict[seasons].append(showName.strip())

else:

mydict[seasons] = [showName.strip()]

f = open("output.txt", "a")

finalString = ''

for seasons in mydict:

finalString += str(seasons) + ": "

for show in mydict[seasons]:

finalString += show + '; '

f.write(finalString[:-2] + '\n')

finalString = ''

f.close()

PLZ HELP!!! I'm a beginner in coding!

import random

rock,paper,scissors = 1,2,3

choice = int(input("Please choose 1 2 or 3: "))

computer = random.randint(1,3)

player_won = False

draw = False

if choice == computer:

draw = True

elif choice == 1 and computer == 3:

player_won = True

elif choice == 2 and computer == 1:

player_won = True

elif choice == 3 and computer == 2:

player_won = True

if player_won:

print("You won!")

elif not player_won and not draw:

print("The computer won!")

else:

print("It's a draw!")

First, I recommend importing at the beginning of your program. Also, you can combine all your same datatype variables in one line. You also need to cast your user choice to an integer so you can compare it with the computer's choice. I wrote the if, elif, and else statements using a boolean variable. I simply wrote all the possibilities that would result in the player winning and this would result in the player_won variable being true. If this is the case, we print to the console, "You won!"
