Ask the user to input an integer. Print out the three numbers before it.

Sample Run-
Enter an integer: 4
3
2
1

Answer:

f=float(input("Enter an integer: "))

c=(f-1)

a=(c-1)

b=(a-1)

print(str(c))

print(str(a))

print(str(b))

Explanation:

This will print everything correctly, just copy and paste!

Hello, I desprately need help in python with this question. I have tried everything:This is the question:



4.19 LAB: 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


This is my code:

miles_per_gallon = float(input('miles_per_gallon: '))
dollars_per_gallon = float(input('dollars_per_gallon: '))
dollars_per_mile = dollars_per_gallon/miles_per_gallon


your_value1 = 10 * dollars_per_mile
your_value2 = 50 * dollars_per_mile
your_value3 = 400 * dollars_per_mile

print('{:.2f} {:.2f} {:.2f}'.format(your_value1, your_value2, your_value3))



Can someone tell me what I'm doing incorrectly or show me? Thanks truly.

The reduction of the amount of medication in the body can be modeled by
the equation , where A is the amount at time t, A0 is the amount at
t = 0, and k is the decay constant ( ). The half-life time of a certain
medication is 3.5 h. A person takes 400 mg of the medication at t=0, and
then additional 400 mg every 4 h. Determine the amount of the medication
in a patient’s body 23 h after taking the first dose.
After determining the value of k, define a vector
(the time since taking each dose) and calculate the corresponding values of
A. Then use MATLAB’s built-in function sum to determine the total
amount.
