# Python Program - Find Largest Number among three Numbers

Three numbers $x$, $y$ and $z$ are given and the largest number among these three numbers can be found out using below methods.

### Example: Using If statement

In the below example, only if conditional statements are used.

def largest(x, y, z):
if x >= y and x >= z:
max = x
if y >= x and y >= z:
max = y
if z >= x and z >= y:
max = z
print("largest number among", x,",", y,"and",z,"is: ",max)

largest(100, 50, 25)
largest(50, 50, 25)


Output

largest number among 100 , 50 and 25 is:  100
largest number among 50 , 50 and 25 is:  50


### Example: Using If-else statement

It can also be solved using If-else conditional statements.

def largest(x, y, z):
if x >= y and x >= z:
max = x
elif y >= x and y >= z:
max = y
else:
max = z
print("largest number among", x,",", y,"and",z,"is: ",max)

largest(100, 50, 25)
largest(50, 50, 25)


Output

largest number among 100 , 50 and 25 is:  100
largest number among 50 , 50 and 25 is:  50


### Example: Using Nested If-else statement

The above problem can also be solved using nested if-else conditional statements.

def largest(x, y, z):
if x >= y:
if x >= z:
max = x
else:
max = z
else:
if y >= z:
max = y
else:
max = z
print("largest number among", x,",", y,"and",z,"is: ",max)

largest(100, 50, 25)
largest(50, 50, 25)


Output

largest number among 100 , 50 and 25 is:  100
largest number among 50 , 50 and 25 is:  50


### Example: Using Short hand If-else statement

Short hand if-else conditional statements can also be used here.

def largest(x, y, z):
max = x if x > y else y if y > z else z
print("largest number among", x,",", y,"and",z,"is: ",max)

largest(100, 50, 25)
largest(50, 50, 25)


Output

largest number among 100 , 50 and 25 is:  100
largest number among 50 , 50 and 25 is:  50
