Ternary operator in python

#python #operations #c #cpp

Ternary operator provides short and concise way to write the conditional statements and allows to evaluate and test the condition in a single line of code.

Syntax:
true_value if condition else false_value

Example:

# initialize values x, y = 5, 10 # expression with ternary operator largest = y if x<y else x # print largest result print(largest) Output 10
Enter fullscreen mode Exit fullscreen mode

Like as ternary operator using if..else we can also implement the same using list, tuple, dictionary and lambda.

Using List

Syntax:
[false_value, true_value] [condition]

# initialize values x, y = 5, 10 # expression using List largest [x, y][x < y] = # print largest result print(largest) Output 10
Enter fullscreen mode Exit fullscreen mode

Using Dictionary
Syntax:
{True: true_value, False: false_value} [condition]

# initialize values x, y = 5, 10 # expression using Dictionary largest = {True: y, False: x}[x < y] # print largest result print(largest) Output 10
Enter fullscreen mode Exit fullscreen mode

Using Lambda
Syntax:
(lambda: false_value, lambda: true_value) [condition] ()

# initialize values x, y = 5, 10 # expression using lambda largest = (lambda: x, lambda: y)[x<y]( # print largest result print(largest) Output 10
Enter fullscreen mode Exit fullscreen mode
