We can use list comprehension using if without else in Python.
num = [i for i in range(10) if i>=5]
print(num)Python Example list comprehension if without else
A simple example code compares 2 iterable and prints the items which appear in both iterable.
a = [1, 2, 3, 4, 5]
b = [5, 2, 3]
res = [y for y in a if y in b]
print(res)
Output:
Can an if statement in a list comprehension use an else?
Answer: Yes, an else clause can be used with an if in a list comprehension. The following code example shows the use of an else in a simple list comprehension. The if/else is placed in front of them for a component of the list comprehension.
res = ["Yes" if num % 3 == 0 else "No" for num in range(1, 5)]
print(res)
Output: [‘No’, ‘No’, ‘Yes’, ‘No’]
