Question

1. Number of Kids

Type all the numbers from the whiteboard into a data file n_kids.txt, one number

per line.

Write a program n_kids.py that reads the data from n_kids.txt, does some math, then displays the following:

Total number of families:

Total number of kids:

Average number of kids per family: (to 2 dp)

Maximum number of kids in a family:

Minimum number of kids in a family:

Write the above results to a different file (results.txt, not to the

input file n_kids.txt) in addition to displaying them on the screen. Do not use built in min and max functions.

Answer 1

Implemented the code as per the requirement. As python is indentation specific, you may not get the formatted text while copying the code,
so I'm attaching the screenshots of the code for reference. Please make sure when you are executing the below code you have same format, especially tabs.

Please comment if any modification required or if you need any help.

Code:

====

fil1 = open("F:\\Eclipse_Workspace\\FirstProject\\n_kids.txt", "r+")
total_families=0
total_kids=0
firstline = fil1.readline().strip()
total_families = total_families+1
total_kids = total_kids+int(firstline)
min = int(firstline)
max = int(firstline)
for line in fil1:
    total_families = total_families+1
    number = int(line.strip())
    total_kids = total_kids+ number
    if(min>number):
        min = number
    if(max<number):
        max = number

file_out = open("F:\\Eclipse_Workspace\\FirstProject\\results.txt","w+")
file_out.write("Total number of families: "+str(total_families)+"\n")
print("Total number of families: "+str(total_families))
file_out.write("Total number of kids: "+str(total_kids)+"\n")
print("Total number of kids: "+str(total_kids))
file_out.write("Average number of kids per family: "+str(round((total_kids/total_families),2))+"\n")
print("Average number of kids per family: "+str(round((total_kids/total_families),2)))
file_out.write("Maximum number of kids in a family: "+str(max)+"\n")
print("Maximum number of kids in a family: "+str(max))
file_out.write("Minimum number of kids in a family: "+str(min)+"\n")
print("Minimum number of kids in a family: "+str(min))
