Question

Focus on: Basic list operations, methods, use of functions, and good programming style. Program should be in basic python.

Part 1. Write a program that does the following:
1. Create a list of length N where N is a randomly selected integer between 10 and 20 and
whose elements are randomly selected integers between 0 and 19.
2. Print out the list.
3. Create a copy of the list. Sort the copy into decreasing order and print it.
4. Report the distinct elements in the list
Before continuing with the next two parts, add a function user_input(lo, hi) to your
program. It should ask the user for an integer between lo and hi and return the value. Use
appropriate error handling and input validation.

Part 2.
Write a function named how_many(a_list, a_num) that that expects a list of numbers
and a number as arguments. It returns how many times the number is found in the list.
If the number is not in the list, return 0. For example
how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 )
returns 2

And how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 11 )
returns 0
Ask the user for an integer between 0 and 19. If the number is in the list, report how
many times it occurs.

Part 3.
Write a function named find_bigger(a_list, a_num) that expects as arguments a list of
numbers and a number. It should return a new list consisting of all the numbers in the list
that are greater than the number. For example
find_bigger( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 11 )
returns [12, 15, 16, 15]

And find_bigger( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 )
returns [16]
Ask the user for an integer between 0 and 19 and then report how many of the items in the
list are greater than that number.

Answer 1

Below are the codes with comments  for the above three Parts with output screens

Part1-

Code with comments-

#using laibrary called random 
import random 
#generatin a random integer
myrandom=random.randint(10,20)
#creating empty list 
myrandomlist=[]
#generating random elements 
for i in range(0,myrandom):
    myrandomlist.append(random.randint(0,19))
print("Random list is")
print(myrandomlist)
print()
#copying the list 
myrandomlistcopy=myrandomlist
myrandomlistcopy.sort(reverse=True)
print("Sort of list in decreasing order is")
#soring the list in descending order 
print(myrandomlistcopy)
print()
#generating distinctelements
distinctelements=list(set(myrandomlistcopy))
print("The distinct elements in the list are")
#printing distinctelements
print(distinctelements)
print()

#our user_input function 
def user_input(lo,hi):
    #asking user to input between lo and hi 
    print("Please enter a value between ",lo,"and",hi)
    inputt=int(input())
    #checking if number in range 
    if(inputt<hi and inputt>lo):
        num=random.randint(lo,hi)
        #checking if guessed number is right or not 
        if(inputt==num):
            z="Yes your guess is right"
        else:
            z="Oops your guess is wrong,the correct number is "+str(num)
    #if number not in range program will exit
    else:
        print("Please enter the number in given range next time")
        exit()
    
    #returning the value z
    return z 
#calling the function with parameters lo and hi 
print(user_input(10,20))

Please note the spelling mistake in comment 1 i.r library not laibrary for importing the library "random"

Part2-

Note-You can remove multiline comments from line 9 to 19 if you want to test with your desired values and pass the values to the function

Code with comments-

#function how_many
def how_many(a_list,a_num):
    #checking if numbe ris in list if present return the count of the element 
    if(a_num in list(set(a_list))):
        return a_list.count(a_num)
    #else return 0
    else:
        return 0
"""
print("Please enter How many elements do you want to enter")
c=int(input())
mylist=[]
for i in range(c):
    num=int(input())
    mylist.append(num)
print("Please enter Which element do you want to check")
e=int(input())
print()
"""
#printing the result of the function how_many by passing a list and a number 
print(how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 ))
print()

#asking the user to enter a number 
print("Please enter a element  between 0 and 19")
aa=int(input())
if(aa<19 and aa>0):
    print(how_many([12, 15, 16, 4, 10, 3, 5, 7, 9, 15],aa))
else:
    print("Please enter in between given range nexttime")
