Python: Calculate the sum of the positive and negative numbers of a given list of numbers using lambda function

Python Lambda: Exercise-23 with Solution

Write a Python program to calculate the sum of the positive and negative numbers of a given list of numbers using the lambda function.

Sample Solution:

Python Code :

# Create a list named 'nums' containing integers, including both positive and negative numbers
nums = [2, 4, -6, -9, 11, -12, 14, -5, 17]
# Print the original list 'nums'
print("Original list:", nums)
# Filter the 'nums' list using a lambda function to obtain a list of only negative numbers
total_negative_nums = list(filter(lambda nums: nums < 0, nums))
# Filter the 'nums' list using a lambda function to obtain a list of only positive numbers
total_positive_nums = list(filter(lambda nums: nums > 0, nums))
# Print the sum of all negative numbers obtained in the 'total_negative_nums' list
print("Sum of the negative numbers: ", sum(total_negative_nums))
# Print the sum of all positive numbers obtained in the 'total_positive_nums' list
print("Sum of the positive numbers: ", sum(total_positive_nums))

Sample Output:

Original list: [2, 4, -6, -9, 11, -12, 14, -5, 17]
Sum of the negative numbers:  -32
Sum of the positive numbers:  48
