How to write inline if statement for print in Python

Question

I have a requirement to print content only when a boolean variable is set to True. 

I tried this example:

>>> x = 100
>>> y = True
>>> print x if y
  File "<stdin>", line 1
    print x if y
             ^
SyntaxError: invalid syntax  

Same thing if I write print x if y==True.

What is going wrong here?

Answer 1

Inline if-else expression must always contain the else clause.

For example:

x = 1 if y else 0

If you want to leave the value 'y' variable value unchanged - adding old 'x' value

(Else is needed due to syntax):

x = 1 if y else x

This piece of code leaves x unchanged when y turns to be False.

Hope this helps!!
