If you know c or java, you are probably used to the neat ternary operator which allows you to do stuff like this:
foo = (condition) ? "true" : "false";
Which results in
foo being set to “true” if condition is true and to “false”
otherwise. This is basically just syntactic sugar for this expression:
if (condition): foo = "true"; else: foo = "false";
Fortunately, this is also possible in my favored programming language, Python (and also in R, which I have to use quiet often).
This is the way to go in Python:
foo = "true" if (condition) else "false" #this can be chained foo = "true I" if (condition I) else "true II" if (condition II) else "false"
.. and this is how it’s done in R:
foo = if(condition) "true" else "false" #this can be chained, too foo = if(condition I) "true I" if(condition II) "true II" else "false"
Now you know how to use the ternary operator in Python and R but you should use it with care since the excessive use of the ternary operator can lead to unreadable code. You have been warned…
