Question

Write a Python 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:

Maximum number of kids in a family:

Minimum number of kids in a family:

Extra credit (2 pts): 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. << Mostly need help in finding Min Max without the functions

** So n.kids,txt is just a list of numbers. **

But I need help getting the Min and Max values from the list of numbers.

Any assistance will be appreciated. Will like and comment  

Answer 1

Code:

l = []
#taken an empty list named "l"

#opened the file named "n_kids.txt" and appended each line in it to the list
with open ("n_kids.txt", 'r') as x:
    for row in x:
        l.append(int(row))

#using for calculating number of families      
f=0
for i in l:
    f+=1

#using for calculating number of kids
k =0
for s in l:
    k+=s
  
#calculating average number of kids per family
average = (k//f)

#calculating maximum kids using for loop and index
maximum = l[0]
for m in l:     
    if m > maximum:
      maximum = m
#calculating minimum kids using for loop and index
minimum = l[0]
for n in l:     
    if n < minimum:
      minimum = n

#printing the output
print("Total number of families:",f)
print("Total number of kids:",k)
print("Average number of kids per family:", average)
print("Maximum number of kids in a family:",maximum)
print("Minimum number of kids in a family:",minimum)

n_kids.txt:

Note: As you asked in the question, I didn't used min() and max() functions

addition to that I didn't used builtin function to calculate other things as well.

Please comment If you want the other things i.e, no of kids, no of families by using builtin function
