How can the ternary operators be used in python?
Also known as conditional expressions. It is used to return a value based on the result of a binary condition. It takes binary value(condition) as an input, so it looks similar to an if-else condition block. However, it also returns a value so behaving similar to a function.
Example-1 - Using ternary operator:
x = 5
y = 6
print("x" if x > y else "y")
# Output:
y
With ternary operator, we are able to write code in one line. So python basically first evaluates the condition, if true evaluate the first expression else evaluates the second condition.
Example-2:
a, b = 30, 20
# Copy value of a if a < b else copy b
min = a if a < b else b
print(min)
# Output:
20
Example-3 - Using python if-else statement:
x, y = 10, 6
if x > y:
print(" 'x' is grater than 'y', x =", x)
else:
print("y =", y)
# Output:
'x' is grater than 'y', x = 10
