Write a function called st_dev. St_dev should have one #parameter, a filename. The file will contain one integer on #each line.

kodGreya [7K]

Answer:

import statistics
def st_dev(file_name):
with open(file_name) as file:
data = file.readlines()
numList = []
for x in data:
numList.append(int(x))
return statistics.pstdev(numList)
print(st_dev("text1.txt"))

Explanation:

The solution code is written using Python.

To ease the calculation task, we can import Python statistics module to use the pstdev method to calculate the population standard deviation of a list of numbers (Line 1).

Next, create a st_dev function that take single argument file_name (Line 3). In the function, it will open the input file and read the data line by line (Line 4-5). Create a for loop to traverse through each line of the data which is an integer and append it to numList (Line 7-8). We can pass the numList to pstdev method (Line 10) and return the resulting standard deviation value as output.

We test the function by passing a file which hold a list of integer values in each line (Line 12).

A cookie recipe calls for the following ingredients: • 1.5 cups of sugar • 1 cup of butter • 2.75 cups of flour The recipe produ

True [87]

The program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient is corresponds to the ingredients mentioned above.

<h3>Further explanation</h3>

Python is a general-purpose programming language. We want to write a python program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient.

48 cookies = 1.5 cups of sugar + 1 cup of butter + 2.75 cups of flour, so:

def main():

cookies = float(input("How many cookies would you like to make?\n>"))

sugar = (1.5 * cookies) / 48.0

butter = cookies / 48

flour = (2.75 * cookies) / 48

print("To make ", cookies, " cookies, you will need:\n", \

format(sugar, '.2f'), " cups of sugar\n", \

format(butter, '.2f'), " cups of butter\n", \

format(flour, '.2f'), " cups of flour", sep='')

redoQuery()

def redoQuery():

yn = input("Would you like to check another batch size? (y/n)\n>")

if yn == 'y':

main()

elif yn =='n':

exit()

else:

print("Please enter only a lowercase \'y\' or lowercase \'n\'," \

"then press enter")

redoQuery()

main()

The run program is shown in the attachment below.
