In this exercise, your function will receive 2 parameters, the name of a text file, and a list of strings. The function will wri

diamong [38]

Answer:

# the function is defined

# it takes 2 arguments: filename and list of string

def solution(filename, listOfString):

# the file is opened in write mode

# so that we can write to it

with open(filename, 'w') as file_object:

# we loop through the entire list of string

# this looping help us know what to write to the file

for each_string in listOfString:

# if the length of the string is less than 4

# we write 'x' with a new line

if len(each_string) < 4:

file_object.write("x\n")

# else if the length of the string is greater than equals 4

# we write the fourth character

# and also add new line

else:

file_object.write(each_string[3])

file_object.write("\n")

Explanation:

The function is written in Python. It takes two argument; filename and list of string.

It opens the file in write mode and then loop through the list of string. During the loop, we know what to write to the file.

In the length of a string is less than 4; we write 'x' else we write the fourth character in the string. The fourth character has an index of 3 because string uses zero index counting like a string. Starting from zero; 0, 1, 2, 3, 4... the fourth character has an index of 3.

To reduce the number of used digital outputs of the microcontroller, the display board is connected to the main board through th

Luda [366]

Answer:

The program in Python is as follows:

BCD = ["0001","0010","0011","0100","0101","0110","0111"]

num = input("Decimal: ")

BCDValue = ""

valid = True

for i in range(len(num)):

if num[i].isdigit():

if(int(num[i])>= 0 and int(num[i])<8):

BCDValue += BCD[i]+" "

else:

valid = False

break;

else:

valid = False

break;

if(valid):

print(BCDValue)

else:

print("Invalid")

Explanation:

This initializes the BCD corresponding value of the decimal number to a list

BCD = ["0001","0010","0011","0100","0101","0110","0111"]

This gets input for a decimal number

num = input("Decimal: ")

This initializes the required output (i.e. BCD value) to an empty string

BCDValue = ""

This initializes valid input to True (Boolean)

valid = True

This iterates through the input string

for i in range(len(num)):

This checks if each character of the string is a number

if num[i].isdigit():

If yes, it checks if the number ranges from 0 to 7 (inclusive)

if(int(num[i])>= 0 and int(num[i])<8):

If yes, the corresponding BCD value is calculated

BCDValue += BCD[i]+" "

else:

If otherwise, then the input string is invalid and the loop is exited

valid = False

break;

If otherwise, then the input string is invalid and the loop is exited

else:

valid = False

break;

If valid is True, then the BCD value is printed

if(valid):

print(BCDValue)

If otherwise, it prints Invalid

else:

print("Invalid")

The length, height, and width of a cube are 10, 7, and 5 cm respectively. Write a program that calculates the volume, perimeter,

RideAnS [48]

Answer:

// code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

int length=10,height=7,width=5;

// find the volume of

int vol=length*height*width;

// find the surface area

int sa=2*(length*width+length*height+height*width);

// find the perimeter

int peri=4*(length+width+height);

// print the volume

cout<<"Volume is: "<<vol<<" cm^3."<<endl;

// print the surface area

cout<<"Surface area is: "<<sa<<" cm^2."<<endl;

// print the perimeter

cout<<"Perimeter is: "<<peri<<" cm."<<endl;

return 0;

}

Explanation:

Declare and initialize length=10, width=5 and height=7.calculate volume by multiply length, width and height and assign to variable "vol".Then find the surface area as 2*(length*width+length*height+height*width) and assign it to variable "sa".Then find the perimeter as 4*(length+width+height) and assign to variable "peri". Print the volume, perimeter and surface area.

Output:

Volume is: 350 cm^3.

Surface area is: 310 cm^2.

Perimeter is: 88 cm.
