Question

The function below takes one parameter: a list of numbers (num_list). Complete the function to return a new list containing only the negative numbers from the original list. For this question, you'll first want to create an empty list. Then, you'll want to visit every element of the original list checking to see if it is negative. For the negative elements, you'll append them to your new list. Finally, return the new list.

Answer 1

Answer:

Following are the program in the Python Programming language.

#define function

def negative_num(num_list):

 #set list type variable

 nlist=[]

 #set the for loop

 for n in num_list:

   #check negative numbers

   if(n<0):

     #add the value of n in list

     nlist.append(n)

 #return list

 return nlist

#set new list type variable that store list

newl=[-5,8,-6,3,-4,9,-7]

#print and call the function

print(negative_num(newl))

Output:

[-5, -6, -4, -7]

Explanation:

Here, we define the function "negative_num" and pass an argument "num_list" in its parameter and inside the function.

• Set new list data type variable "nlist".
• Set the for loop which iterate as the list.
• Set the if conditional statement to check the value of the list is less than 0 then, add that negative values in the variable "nlist".
• Then, return the new list.

Finally, we set a variable "newl" which store the list of negative and positive numbers then, we print and call the function.
