The ternary operator in Python allows you to quickly define a conditional.
Let’s say you have a function that compares an
age variable to the
18 value, and return True or False depending on the result.
Instead of writing:
def is_adult(age): if age > 18: return True else: return False
You can implement it with the ternary operator in this way:
def is_adult(age): return True if age > 18 else False
First you define the result if the condition is True, then you evaluate the condition, then you define the result if the condition is false:
<result_if_true> if <condition> else <result_if_false>
