How Can You Use Conditional Statements in Python List Comprehensions?

Conditional Statements in List Comprehensions

In Python, it is possible to use conditional statements to manipulate elements in a list comprehension. This allows for conditional execution of operations within the list comprehension.

To achieve conditional behavior in a list comprehension, utilize the following syntax:

[ expression if condition else another_expression for item in sequence ]

Where:

• expression is the operation to perform when the condition is True.
• condition is the condition that determines which expression should be used.
• another_expression is the operation to perform when the condition is False.
• item is each element in the input sequence.

Example:

Consider the following list:

l = [22, 13, 45, 50, 98, 69, 43, 44, 1]

To add 1 to numbers greater than or equal to 45 and add 5 to numbers less than 45 using a list comprehension, use the following code:

result = [x + 1 if x >= 45 else x + 5 for x in l]

This results in the following list:

[27, 18, 46, 51, 99, 70, 48, 49, 6]

In this example, the condition x >= 45 determines whether to add 1 or 5 to each element x.
