Write a program to display MPH (Miles per Hour). Create a function to calculate the MPH. Ask the user for the number of miles dr

puteri [66]

Answer:

In Python:

def MPH(miles,minutes):

mph = round(60 * miles/minutes,1)

return mph

miles = float(input("Miles: "))

minutes = float(input("Minutes: "))

if miles>0 and minutes>0:

print("MPH: ",MPH(miles,minutes))

else:

print("Positive inputs only")

Explanation:

This defines the function

def MPH(miles,minutes):

This calculates mph rounded to 1 decimal place

mph = round(60 * miles/minutes,1)

This returns the calculated mph

return mph

The main begins here

This gets input for miles

miles = float(input("Miles: "))

This gets input for minutes

minutes = float(input("Minutes: "))

If miles and minutes are positive

if miles>0 and minutes>0:

This calls the MPH function

print("MPH: ",MPH(miles,minutes))

If otherwise, this prompts the user for positive inputs

else:

print("Positive inputs only")

Write a program that accepts a positive integer N as command-line argument, and outputs True if N is the square of some integer,

Ann [662]

Answer:

In Python:

N = int(input("Positive integer: "))

if N > 0:

flag = False

for i in range(1,N+1):

if i * i == N:

flag = True

break

print(str(flag))

else:

print("Positive integer only")

Explanation:

N = int(input("Positive integer: "))

If the number is positive

if N > 0:

This initializes a boolean variable to false

flag = False

This iterates from 1 to the input integer

for i in range(1,N+1):

This checks if th number is a square of some integer

if i * i == N:

If yes, flag is set to true

flag = True

The loop is exited

break

This prints either true or false, depending on the result of the loop

print(str(flag))

If otherwise, that the number is not positive

else:

print("Positive integer only")

Write a program that accepts three decimal numbers as input and outputs their sum

Sophie [7]

Answer:

sum = 0.0

for i in range(0,3):

sum += float(input("Enter a decimal number to sum: "))

print ("Sum: ", sum)

*** Sample Input ***

Enter a decimal number to sum: 1.1

Enter a decimal number to sum: 2.2

Enter a decimal number to sum: 3.3

*** Sample Output ***

Sum: 6.6

Explanation:

For this problem, a method was devised in python to create the sum of three individual decimal numbers.

The first line of code, sum = 0.0, initializes a variable to the float type in which we will store the value of our sum. Note, it is initialized to 0.0 to start from a value of 0 and be considered a float.

The second line of code, for i in range(0,3): is the creation of a for loop control structure. This will allow us to repeat a process 3 amount of times using the iterator i, from value 0 to 3 in this case. Note, 0 is inclusive and 3 is exclusive in the python range. This means the for loop will iterate with, i=0, i=1, and i=2.

The third line of code, sum += float(input("Enter a decimal number to sum: ")) is simply asking the user for a number, taking that input and converting it from a string into a float, and then summing the value with the previous value of sum and saving that into sum.

The fourth line of code, print ("Sum: ", sum) is simply displaying the final value that was calculated by adding the three user inputs together which were stored into the variable sum.

Cheers.
