CYB/130 Week 1 Python LAB 2.32: Using math functions
Given three floating-point numbers x, y, and z, output x to the power of z, x to the power of (y to the power of z), the absolute value of (x minus y), and the square root of (x to the power of z).

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f} {:.2f} {:.2f} {:.2f}'.format(your_value1, your_value2, your_value3, your_value4))

Ex: If the input is:
5.0
1.5
3.2
Then the output is:
172.47 361.66 3.50 13.13

CYB/130 Week 1 Python LAB 2.31: Expression for calories burned during workout
The following equations estimate the calories burned when exercising (source):

Women: Calories = ( (Age x 0.074) — (Weight x 0.05741) + (Heart Rate x 0.4472) — 20.4022 ) x Time / 4.184

Men: Calories = ( (Age x 0.2017) + (Weight x 0.09036) + (Heart Rate x 0.6309) — 55.0969 ) x Time / 4.184

Write a program using inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output calories burned for women and men.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('Men: {:.2f} calories'.format(calories_man))

Ex: If the input is:
49
155
148
60
Then the output is:
Women: 580.94 calories
Men: 891.47 calories

CYB/130 Week 1 Python LAB 2.30: Driving costs
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f} {:.2f} {:.2f}'.format(your_value1, your_value2, your_value3))

Ex: If the input is:
20.0
3.1599
Then the output is:
3.16 11.85 79.00
Note: Real per-mile cost would also include maintenance and depreciation.

CYB/130 Week 2 Python LAB 3.14: Simple statistics
Given 4 floating-point numbers. Use a string formatting expression with conversion specifiers to output their product and their average as integers (rounded), then as floating-point numbers.

Output each rounded integer using the following:
print('{:.0f}'.format(your_value))

Output each floating-point value with three digits after the decimal point, which can be achieved as follows:
print('{:.3f}'.format(your_value))

Ex: If the input is:
8.3
10.4
5.0
4.8
the output is:
2072 7
2071.680 7.125

CYB/130 Week 2 Python LAB 3.13: Input and formatted output: House real estate summary
Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:
200000
210000
the output is:
This house is $200000. The change is $-10000 since last month.
The estimated monthly mortgage is $850.00.

Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.

CYB/130 Week 2 Python LAB 3.12: Phone number breakdown
Given an integer representing a 10-digit phone number, output the area code, prefix, and line number using the format (800) 555-1212.

Ex: If the input is:
8005551212
the output is:
(800) 555-1212

Hint: Use % to get the desired rightmost digits. Ex: The rightmost 2 digits of 572 is gotten by 572 % 100, which is 72.
Hint: Use // to shift right by the desired amount. Ex: Shifting 572 right by 2 digits is done by 572 // 100, which yields 5. (Recall integer division discards the fraction).

For simplicity, assume any part starts with a non-zero digit. So 0119998888 is not allowed.

CYB/130 Week 4 Python LAB 5.20: Step counter
A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:
5345
the output is:
2.67

Your program must define and call the following function. The function should return the amount of miles walked.
def steps_to_miles(user_steps)

CYB/130 Week 4 Python LAB 5.19: Driving costs - functions
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:
20.0
3.1599
the output is:
1.58
7.90
63.20

Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles.

Ex: If the function is called with:
50  20.0  3.1599
the function returns:
7.89975

def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon)
Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles.
Note: This is a lab from a previous chapter that now requires the use of a function.

CYB/130 Week 4 Python LAB 5.18: Miles to track laps
One lap around a standard high-school running track is exactly 0.25 miles. Write the function miles_to_laps() that takes a number of miles as an argument and returns the number of laps. Complete the program to output the number of laps.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:
1.5
the output is:
6.00

Ex: If the input is:
2.2
the output is:
8.80

Your program must define and call the following function:
def miles_to_laps(user_miles)
