Python: Filter a list of integers using Lambda
Python Lambda: Exercise-5 with Solution
Write a Python program to filter a list of integers using Lambda.
Sample Solution:
Python Code :
nums = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print("Original list of integers:")
print(nums)
print("\nEven numbers from the said list:")
even_nums = list(filter(lambda x: x%2 == 0, nums))
print(even_nums)
print("\nOdd numbers from the said list:")
odd_nums = list(filter(lambda x: x%2 != 0, nums))
print(odd_nums)
Sample Output:
Original list of integers: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] Even numbers from the said list: [2, 4, 6, 8, 10] Odd numbers from the said list: [1, 3, 5, 7, 9]
Visualize Python code execution:
The following tool visualize what the computer is doing step-by-step as it executes the said program:
Test for a single number:
Python Code :
print((lambda x: (x % 2 and 'Odd number' or 'Even number'))(5))
print((lambda x: (x % 2 and 'Odd number' or 'Even number'))(8))
Sample Output:
Odd number Even number
