Problem 00

Write a program that prints "My first submission!" to standard output.

Problem 01

Write a program that prints "Hello, {name}!" where {name} is your name.

• Example: "Hello, Jack!"

Problem 02

Write a program that calculates the volume of a cone with a radius of 5 and a height of 9.

Problem 03

Write a program that converts 40 degrees Celsius to degrees Fahrenheit.

Hint

F = C * 9/5 + 32

Problem 04

Write a program that computes the roots of x² + 16x + 52 = 0.

Hint 1

Two rational roots exist.

Hint 2

The quadratic equation might help

Solutions

problem00.py

print("My first submission!")

problem01.py

Suitable:

print("Hello, Jack!")

But this is better:

name = "Jack"
print(f"Hello, {name}!")

problem02.py

PI = 3.14159
radius = 5
height = 9
volume = 1 / 3 * radius * radius * height * PI
print(volume)

or

import math
radius = 5
height = 9
volume = 1 / 3 * pow(radius, 2) * height * math.pi
print(f"volume = {volume}")

problem03.py

c = 40
f = c * 9/5 + 32
print(f"{c} degrees Celsius is {f} degrees Fahrenheit")

problem04.py

import math
# x^2 + 16x + 52 = 0
# a^2 + bx + c form
a = 1
b = 16
c = 52
root_1 = (-b + math.sqrt(b*b - 4*a*c)) / (2*a)
root_2 = (-b - math.sqrt(b*b - 4*a*c)) / (2*a)
print(root_1, root_2)

Alternatively

import math
a = 1
b = 16
c = 52
discriminant = b*b - 4*a*c
root_1 = (-b + math.sqrt(discriminant)) / (2*a)
root_2 = (-b - math.sqrt(discriminant)) / (2*a)
print(root_1,root_2)
