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 lambda function.

Sample Solution:

Python Code :

nums = [2, 4, -6, -9, 11, -12, 14, -5, 17]
print("Original list:",nums)

total_negative_nums = list(filter(lambda nums:nums<0,nums))
total_positive_nums = list(filter(lambda nums:nums>0,nums))

print("Sum of the positive numbers: ",sum(total_negative_nums))
print("Sum of the negative numbers: ",sum(total_positive_nums))

Sample Output:

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

Function argument unpacking in Python.

Example:

def tips_func(x, y, z):
  print(x, y, z)
  
tuple_val = (2, 0, 2)
dict_val = {'x': 3, 'y': 2, 'z': 1}
tips_func(*tuple_val)
tips_func(**dict_val)

Output:

2 0 2
3 2 1
