list comprehension python if else

1[statement if condition else statement for _ in iterable_object]
2#statement are without assignment

4# Basic syntax for if else:

10# Example usage:
11# Say you want to return the square of elements if elements are less 
12# than 10, otherwise you just want to return the elements themselves:
13your_list = [1, 7, 13, 11, 23, 2, 17, 42, 8, 5]
14new_list = [x**2 if x < 10 else x for x in your_list]
15print(new_list)
16--> [1, 49, 13, 11, 23, 4, 17, 42, 64, 25]
