List comprehension vs. lambda + filter – python

List comprehensions and lambda with filter are both used for creating filtered lists in Python, but they differ in readability and flexibility.

List comprehension: Concise and Pythonic, it combines filtering and mapping in a single, easy-to-read construct. Example:

nums = [1, 2, 3, 4]
evens = [x for x in nums if x % 2 == 0] # Output: [2, 4]

Lambda + filter: Uses the filter() function with a lambda to specify the filtering condition. Example:

nums = [1, 2, 3, 4]
evens = list(filter(lambda x: x % 2 == 0, nums)) # Output: [2, 4]

List comprehensions are generally preferred for clarity.
