inline if python code example

Example 1: if condition in print statement python

print (a if b else 0)

Example 2: implicit if python

x = a if b else 0

Example 3: if else python in single line

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

Example 4: how to perform inline if in python

expression_if_true if condition else expression_if_false

Example 5: python inline if

Python does not have a trailing if statement.
There are two kinds of if in Python:

1. if statement:

  if condition: statement
  if condition:
      block
      
2. if expression (introduced in Python 2.5)

	expression_if_true if condition else expression_if_false

And note, that both print a and b = a are statements. Only the a part is an expression. So if you write
  print a if b else 0
  
it means
	print (a if b else 0)
  
and similarly when you write
	x = a if b else 0
  
it means
	x = (a if b else 0)
  
Now what would it print/assign if there was no else clause? The print/assignment is still there.
And note, that if you don't want it to be there, you can always write the regular if statement on a single line, though it's less readable and there is really no reason to avoid the two-line variant.
