How can I condense my Python if-then-else statements into a single line?

One-Line If-Then-Else Statements in Python

In Python, you can write if-then-else statements on a single line using the ternary operator. This operator follows the syntax:

value_when_true if condition else value_when_false

For example, the following if-then-else statement can be written on one line:

if count == N:
    count = 0
else:
    count = N + 1

Using the ternary operator, this becomes:

count = 0 if count == N else count + 1

This operator is useful when you want to assign a value based on a simple condition.

Example:

is_apple = 'Yes' if fruit == 'Apple' else 'No'

Comparison to If Syntax:

Here's an example of how the ternary operator compares to traditional if syntax:

# Ternary operator
fruit = 'Apple'
is_apple = True if fruit == 'Apple' else False

# If-else syntax
fruit = 'Apple'
is_apple = False
if fruit == 'Apple':
    is_apple = True

Both approaches achieve the same result, but the ternary operator offers a more concise and elegant syntax for simple conditional assignments.
