Putting a simple if-then-else statement on one line

Posted By: Anonymous

I’m just getting into Python and I really like the terseness of the syntax. However, is there an easier way of writing an if–then–else statement so it fits on one line?

For example:

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

Is there a simpler way of writing this? I mean, in Objective-C I would write this as:

count = count == N ? 0 : count + 1;

Is there something similar for Python?

Update

I know that in this instance I can use count == (count + 1) % N.

I’m asking about the general syntax.

Solution

That’s more specifically a ternary operator expression than an if-then, here’s the python syntax

value_when_true if condition else value_when_false

Better Example: (thanks Mr. Burns)

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

Now with assignment and contrast with if syntax

fruit = 'Apple'
isApple = True if fruit == 'Apple' else False

vs

fruit = 'Apple'
isApple = False
if fruit == 'Apple' : isApple = True
