Question

Write a program to read a list of n integers (positive as well as negative). Create two new lists, one having all positive numbers and the other having all negative numbers from the given list. Print all three lists.

Answer 1

#Defining empty list

list1 = list()

#Getting the input of number of elements to be added in the list

inp = int(input("How many elements do you want to add in the list?

(Element can be both positive and negative) "))

#Taking the input of elements to be added

for i in range(inp):

a = int(input("Enter the elements: "))

list1.append(a)

#Printing the list

print("The list with all the elements: ",list1)

#Defining list2 and list3 to store positive and negative elements of the

list

list2 = list()

list3 = list()

#Looping through list to segregate positive and negative numbers

for j in range(inp):

if list1[j] < 0:

#Appending negative elements to list3

list3.append(list1[j])

else:

#Appending positive elements to list2

list2.append(list1[j])

print("The list with positive elements: ",list2)

print("The list with negative elements: ",list3)

OUTPUT:

How many elements do you want to add in the list? (Element can be

both positive and negative) 5

Enter the elements: -1

Enter the elements: -2

Enter the elements: -3

Enter the elements: 4

Enter the elements: 5

The list with all the elements: [-1, -2, -3, 4, 5]

The list with positive elements: [4, 5]

The list with negative elements: [-1, -2, -3]
