Lecture 80:-  Get Smaller Elements In Python

 

To get the smaller elements from a list or any iterable in Python, you can use a list comprehension or the built-in filter() function. Here's how you can do it:

  1. Using List Comprehension:

pythonCopy code

numbers = [10, 5, 7, 3, 8, 2, 9, 6] # Get smaller elements using list comprehension smaller_elements = [num for num in numbers if num < 7] print(smaller_elements)  # Output: [5, 3, 2, 6]

In this example, the list comprehension [num for num in numbers if num < 7] iterates through each element in the numbers list and selects only those elements that are smaller than 7.

  1. Using filter() function:

pythonCopy code

numbers = [10, 5, 7, 3, 8, 2, 9, 6] # Define a function to check if an element is smaller than 7 def is_smaller_than_seven(num):    return num < 7 # Use filter() to get smaller elements smaller_elements = list(filter(is_smaller_than_seven, numbers)) print(smaller_elements)  # Output: [5, 3, 2, 6]

In this example, we define a function is_smaller_than_seven() that returns True if the input element is smaller than 7. The filter() function takes this function and the numbers list as arguments and returns an iterator containing elements that satisfy the condition defined in the is_smaller_than_seven() function. We convert the iterator to a list using list() to get the smaller elements as a list.

Both methods will give you the list of elements that are smaller than the specified value (7 in this case). Choose the one that fits your coding style or use-case better. The list comprehension is often considered more concise and Pythonic, while the filter() function may be useful when dealing with more complex conditions.
