In Python, you can write an if statement in a single line using a shorthand code known as the ternary operator. The ternary operator allows you to write a conditional expression in a concise and readable way.
Here's an example of how to use the ternary operator to write an if statement in a single line of code:
# Example 1
x = 10
y = 20
print("x is greater than y" if x > y else "y is greater than or equal to x")
In this example, the ternary operator is used to print a message based on the comparison of two variables x
and y
. If x
is greater than y
, it will print "x is greater than y", otherwise it will print "y is greater than or equal to x".
You can also use the ternary operator in a more complex if statement that contains multiple conditions:
# Example 2
a = 5
b = 10
c = 15
print("a is the largest" if a > b and a > c else "b is the largest" if b > a and b > c else "c is the largest")
In this example, the ternary operator is used to determine which variable (a
, b
, or c
) is the largest. If a
is greater than both b
and c
, it will print "a is the largest". If b
is greater than both a
and c
, it will print "b is the largest". Otherwise, it will print "c is the largest".
Keep in mind that while using the ternary operator can make your code more concise, it can also make it harder to read and understand, especially for more complex conditions. Use it judiciously and prioritize readability and maintainability over brevity.
