Sum of prime number of list in python by R4R Team

Example-

list is l=[2,3,6,7,8,9,11,12,13]
then sum of prime number in list is 2+3+7+11+13=36


program-

#import the functools module
import functools

l=[2,3,4,5,6,7,9,10,11,11,13,17,15]
print("List is ",l)

def findprime(n):
for i in range(2,int(n/2)+1):
if n%i==0:
return False
return True

#first way
sum=0
for i in l:
if findprime(i):
sum+=i
print("Sum of prime number is :",sum)

#second way
l=filter(findprime,l )
sum=functools.reduce(lambda x,y:x+y,l)
print("Sum of prime number is :",sum)

output-

List is [2, 3, 4, 5, 6, 7, 9, 10, 11, 11, 13, 17, 15]
Sum of prime number is : 69
Sum of prime number is : 69

-In this program, we have a list [2,3,4,5,6,7,9,10,11,11,13,17,15], then prime numbers in this list is 2,3,5,7,11,13,17 then there sum is 69.
-findprime() function is return True if the number is prime otherwise it return False.
-Filter() function filter all prime number from the list.
- reduce() function are capable to sum up the all items in the list.
