Python has conditional expressions which are sometimes called a “ternary operator“. If you need to use statements, you have to use a normal
if statement instead of a conditional expression.
In Python, the conditional expression is written as follows.
X if condition else Y
Python conditional expression example
Simple example code.
a = 10 result = 'Even' if a % 2 == 0 else 'Odd' print(result)
List comprehensions and conditional expressions
l = [0 if i % 2 == 0 else 1 for i in range(10)] print(l)
Output: [0, 1, 0, 1, 0, 1, 0, 1, 0, 1]
Lambda expressions and conditional expressions
res = lambda x: 'even' if x % 2 == 0 else 'odd' print(res(10))
Does Python have a ternary conditional operator?
Answer: Yes, it was added in version 2.5. The expression syntax is:
a if condition else b
condition is evaluated, then exactly one of either
b is evaluated and returned based on the Boolean value of
condition evaluates to
a is evaluated and returned but
b is ignored, or else when
b is evaluated and returned but
a is ignored.
Use conditional expressions to assign a variable like so:
a = True x = 0 if True else 1 print(x)
