Ternary Operator with examples in Python

Ternary Operator in Python

In python ternary operator is used to return a value based on the result of a binary condition.  first It takes the binary value(condition) as an input, so it looks similar to an “if-else” condition block, and replace the multiple lines of if-else, to reduce the complexity.

Syntax of Simple Method 

we will compare this with a if-else through a piece of code

x, y = 4,3

if x>y :

      print ("x")

else :

      print ("y")

output :

x

Now we will see same thing through the ternary operator

x, y = 4,3

print("x" if x>y else "y")

output :

x

Using Ternary and Dictionary

Now we will see the use of this operator directly in ternary and dictionary.

a, b = 15, 22

print( (b, a) [a < b] )  

print({True: a, False: b} [a < b])




print((lambda: b, lambda: a)[a < b]())

output :

15
15
15

Lets see this approach separately 

In Tuple

a, b = random(), random()

(b, a) [a>b]

output :

0.5497848117028667

In Dictionary

 a, b = random(), random()

 {False: f"b:{b}", True: f"a:{a}"}[a>b]

output :

'a:0.8089581560973976'

Nested Ternary Operator

a, b = 15, 22

  

print ("a and b are equal according to the condition" if a == b else "a is greater than b"

        if a > b else "b is greater than a") # to check the greatest

output :

b is greater than a
