Putting a simple if-then-else statement on one line [duplicate]

python if-statement syntax ternary-operator

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

fruit = 'Apple'isApple = Falseif fruit == 'Apple' : isApple = True

python if-statement syntax ternary-operator

Moreover, you can still use the "ordinary" if syntax and conflate it into one line with a colon.

if i > 3: print("We are done.")

field_plural = Noneif field_plural is not None: print("insert into testtable(plural) '{0}'".format(field_plural))

python if-statement syntax ternary-operator

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

- the ternary operator. Although I'd say your solution is more readable than this.
