python comprehension for array if else code example
Example 1: python if else list comprehension
desired_elements = [f(x) for x in iterable_object if condition]
desired_elements = [f(x) if condition else g(x) for x in iterable_object]
desired_elements = [f(x) if condition elif condition_2 g(x) else h(x) for x in iterable_object]
your_list = [1, 7, 13, 11, 23, 2, 17, 42, 8, 5]
new_list = [x**2 if x < 10 else x for x in your_list]
print(new_list)
--> [1, 49, 13, 11, 23, 4, 17, 42, 64, 25]
Example 2: python list comprehension if else
>>> original_prices = [1.25, -9.45, 10.22, 3.78, -5.92, 1.16]
>>> prices = [i if i > 0 else 0 for i in original_prices]
>>> prices
[1.25, 0, 10.22, 3.78, 0, 1.16]
