InfyTQ Solution in Python

PROBLEM STATEMENT

Given a list of integers and a number. Write a python function to find and return the sum of the elements of the list.
Note: Don't add the given number and also the numbers present before and after the given number in the list .

Sample Input	Expected Output
list=[1,2,3,4], number=2	4
list=[1,2,2,3,5,4,2,2,1,2],number=2	5
list=[1,7,3,4,1,7,10,5],number=7	9
list=[1,2,1,2],number=2	0

SOLUTION

#PF-Prac-31 def sum_of_elements(num_list,number): result_sum=0 for i in num_list: if(i==number): blacklist=num_list.index(number) num_list[blacklist]=0 num_list[blacklist+1]=0 num_list[blacklist-1]=0 else: continue for i in range(0,len(num_list)): result_sum=result_sum+num_list[i] return result_sum num_list=[1,7,3,4,1,7,10,5] number=7 print(sum_of_elements(num_list, number))
