Python: Remove None value from a given list using lambda function

Python Lambda: Exercise-52 with Solution

Write a Python program to remove None value from a given list using lambda function.

Sample Solution:

Python Code :

def remove_none(nums):
    result = filter(lambda v: v is not None, nums)
    return list(result)

nums = [12, 0, None, 23, None, -55, 234, 89, None, 0, 6, -12]
print("Original list:")
print(nums)
print("\nRemove None value from the said list:")
print(remove_none(nums))

Sample Output:

Original list:
[12, 0, None, 23, None, -55, 234, 89, None, 0, 6, -12]

Remove None value from the said list:
[12, 0, 23, -55, 234, 89, 0, 6, -12]

Python: Tips of the Day

Splits values into two groups. If an element in filter is True, the corresponding element in the collection belongs to the first group; otherwise, it belongs to the second group

Example:

def tips_bifurcate(lst, filter):
  return [
    [x for i, x in enumerate(lst) if filter[i] == True],
    [x for i, x in enumerate(lst) if filter[i] == False]
  ]

print(tips_bifurcate(['little', 'boo', 'peep', 'sat'], [True, True, False, True]))

Output:

[['little', 'boo', 'sat'], ['peep']]
