Answer:

The answer is "Option C".

Explanation:

Dictionary is a set of unsorted data values, that is used to save data like a map and which contains a key: value pair in comparison to many other types of data, which only carry a specific number as just an element.

If we use Dictionary as an array so, it uses a two-pointer variable, one for hold key, and the second is used to hold its value.

Answer:

See explaination

Explanation:

Code for detect_column_level_data_entry_errors.py:

# File: detect_column_level_data_entry_errors.py

# The program will produce a diagnostic report that shows data entry errors that cause column

# totals in the data to be out of balance. Will need to fix cleaned_data.txt until errors resolved.

def main():

input_filename = input('Please enter the input filename: ')

infile = open(input_filename, 'r', encoding='utf8')

total_males = 0

total_females = 0

sum_total = 0

print('\n{0:^40}'.format('Column-Level Data Entry Errors'))

print('\n{0:<10}{1:>10}{2:>10}{3:>10}'.format(

'Age Group', 'Males', 'Females', 'Total'))

for line in infile:

age_group, males, females, total = line.split()

males = int(males)

females = int(females)

total = int(total)

print('{0:<10}{1:>10,}{2:>10,}{3:>10,}'.format(

age_group, males, females, total))

if age_group != 'Total':

total_males = males + total_males

total_females = females + total_females

sum_total = total + sum_total

else:

print('{0:<10}{1:>10,}{2:>10,}{3:>10,}'.format(

'Error', (males-total_males), (females-total_females), (total-sum_total)))

infile.close()

main()

adell [148]

The most likely type of instruction that was executed by the CPU is: a jump instruction.

<h3>What is a CPU?</h3>

A central processing unit (CPU) can be defined as the main components of a computer because it acts as the brain of a computer and does all the processing and logical control.

This ultimately implies that, a central processing unit (CPU) is typically used by a computer to execute an instruction or set of instructions when powered on.

<h3>What is a jump instruction?</h3>

In Computer technology, a jump instruction specifies an offset to a new place in the program sequence when processing an instruction or set of instructions in a computer.

This assignment is to code a simple hangman game. The game should choose a random word out of a list of words that are coded int
pshichka [43]

Answer:

Programming language not stated.

I'll use python for this question

Explanation:

import random

# library that we use in order to choose

# on random words from a list of words

words = ['rain, 'computer', 'science', 'program, 'python', 'mathematics', 'player', 'condition','reverse', 'water', 'board', 'geeks','learn','school','days','scholar','collar','flood','house','flies']

# Function will choose one random word from this list of words

word = random.choice(words)

print("Guess the word")

guesses = ''"

# 5 turns

turns = 5

while turns > 0:

# counts the number of times a user fails

failed = 0

# all characters from the input word taking one at a time.

for char in word:

# comparing that character with the character in guesses

if char in guesses:

print(char)

else:

print("_")

# for every failure 1 will be incremented in failure

failed += 1

if failed == 0:

# user will win the game if failure is 0 and 'You Win' will be given as output

print("You Win")

# this print the correct word

print("The word is: ", word)

break

# if user has input the wrong alphabet then it will ask user to enter another alphabet

guess = input("guess a character:")

# every input character will be stored in guesses

guesses += guess

# check input with the character in word

if guess not in word:

turns -= 1

# if the character doesn’t match the word then “Wrong” will be given as output

print("Wrong")

# this will print the number of turns left for the user

print("You have", + turns, 'more guesses')

if turns == 0:

print("You Loose")
