Answer:

def is a keyword used to define a function, placed before a function name provided by the user to create a user-defined function

__init__ is one of the reserved methods in Python. In object oriented programming, it is known as a constructor. Python will call the __init__() method automatically when you create a new object of a class, you can use the __init__() method to initialize the object’s attributes.

Example code:

class Person:

def __init__(self, name, age):

self.name = name

self.age = age

p1 = Person("John", 36)

print(p1.name)

print(p1.age)

Summary

Use the __init__() method to initialize the instance attributes of an object.

The __init__() doesn’t create an object but is automatically called after the object is created.

Climatologist use weather balloons, stethoscopes, and satellites true or false

Nonamiya [84]

Answer:

False.

Explanation:

A stethoscope is a medical instrument which is used for listening to the work of the heart and lungs. It consists of a microphone that rests on the patient's chest, and rubber tubes that bring the sound to the earphones. An ordinary stethoscope does not have any moving or electrical parts, as it only mechanically conducts sound from the patient's chest to the doctor's ear. One of the simplest examinations that doctors perform today is listening to the lungs and heart with a stethoscope. With the help of this instrument, noises are heard during the work of the lungs and heart.

CS160 Computer Science I In class Lab 10

lianna [129]

Answer:

The program in Python is as follows:

fname = input("Enter the translation file name: ")

with open(fname) as file_in:

lines = []

for line in file_in:

lines.append(line.rstrip('\n'))

myDict = {}

for i in range(len(lines)):

x = lines[i].split(":")

myDict[x[0].lower()] = x[1].lower()

print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")

word = input("Enter an English word: ")

while(True):

if not word:

break

if word.lower() in myDict:

print("The Spanish word is ",myDict[word.lower()])

else:

print("I don’t have that word in my list.")

word = input("Enter an English word: ")

Explanation:

This prompts the user for file name

fname = input("Enter the translation file name: ")

This opens the file for read operation

with open(fname) as file_in:

This creates an empty list

lines = []

This reads through the lines of the file

for line in file_in:

This appends each line as an element of the list

lines.append(line.rstrip('\n'))

This creates an empty dictionaty

myDict = {}

This iterates through the list

for i in range(len(lines)):

This splits each list element by :

x = lines[i].split(":")

This populates the dictionary with the list elements

myDict[x[0].lower()] = x[1].lower()

This prints an instruction on how to use the program

print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")

This prompts the user for an English word

word = input("Enter an English word: ")

This loop is repeated until the user presses the ENTER key

while(True):

If user presses the ENTER key

if not word:

The loop is exited

break

If otherwise, this checks if the word exists in the dictionary

if word.lower() in myDict:

If yes, this prints the Spanish translation

print("The Spanish word is ",myDict[word.lower()])

If otherwise,

else:

Print word does not exist

print("I don’t have that word in my list.")

Prompt the user for another word

word = input("Enter an English word: ")

The prepaid tuition plan covers

rusak2 [61]

Hey there!

A prepaid tuition plan is a plan that allows you to pay the current rate of tuition now (say, years in advance), even if it's much higher than the time when the payment for tuition would actually be paid. This plan is great for anyone who wants to pay a lower price for high–cost education now (even if their kid isn't college age yet) and not have to worry about economic standing or inflation in the future that could drive the tuition prices up.

The plan only covers tuition and other similar fees. You can not purchase books or room and board with it in advance. So, your answer should be: C. Tuition and Fees.

Hope this helped you out! :-)

Write a program that first calls a function to calculate the square roots of all numbers from 1 to 1,000,000 and write them to a

svlad2 [7]

Answer:

The csharp program to compute square roots of numbers and write to a file is as follows.

class Program

{

static long max = 1000000;

static void writeRoots()

{

StreamWriter writer1 = new StreamWriter("roots.txt");

double root;

for (int n=1; n<=max; n++)

{

root = Math.Sqrt(n);

writer1.WriteLine(root);

}

static void Main(string[] args)

{

writeRoots();

}

The program to compute squares of numbers and write to a file is as follows.

class Program

{

static long max = 1000000;

static void writeSquares()

{

StreamWriter writer2 = new StreamWriter("squares.txt");

long root;

for (int n = 1; n <= max; n++)

{

root = n*n;

writer2.WriteLine(root);

}

static void Main(string[] args)

{

writeSquares();

}

Explanation:

1. An integer variable, max, is declared to hold the maximum value to compute square root and square.

2. Inside writeRoots() method, an object of StreamWriter() class is created which takes the name of the file as parameter.

StreamWriter writer1 = new StreamWriter("roots.txt");

3. Inside a for loop, the square roots of numbers from 1 to the value of variable, max, is computed and written to the file, roots.txt.

4. Similarly, inside the method, writeSquares(), an object of StreamWriter() class is created which takes the name of the file as parameter.

StreamWriter writer2 = new StreamWriter("squares.txt");

5. Inside a for loop, the square of numbers from 1 to the value of the variables, max, is computed and written to the file, squares.txt.

6. Both the methods are declared static.

7. Inside main(), the method writeRoots() and writeSquares() are called in their respective programs.

8. Both the programs are written using csharp in visual studio. The program can be tested for any operation on the numbers.

9. If the file by the given name does not exists, StreamWriter creates a new file having the given name and then writes to the file using WriteLine() method.

10. The csharp language is purely object-oriented language and hence all the code is written inside a class.
