# Python Program - Find Smallest Number among three Numbers

Three numbers $x$, $y$ and $z$ are given and the smallest 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 smallest(x, y, z):
if x <= y and x <= z:
min = x
if y <= x and y <= z:
min = y
if z <= x and z <= y:
min = z
print("Smallest number among", x,",", y,"and",z,"is: ",min)

smallest(100, 50, 25)
smallest(50, 50, 25)


Output

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


### Example: Using If-else statement

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

def smallest(x, y, z):
if x <= y and x <= z:
min = x
elif y <= x and y <= z:
min = y
else:
min = z
print("Smallest number among", x,",", y,"and",z,"is: ",min)

smallest(100, 50, 25)
smallest(50, 50, 25)


Output

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


### Example: Using Nested If-else statement

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

def smallest(x, y, z):
if x <= y:
if x <= z:
min = x
else:
min = z
else:
if y <= z:
min = y
else:
min = z
print("Smallest number among", x,",", y,"and",z,"is: ",min)

smallest(100, 50, 25)
smallest(50, 50, 25)


Output

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


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

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

def smallest(x, y, z):
min = x if x < y else y if y < z else z
print("Smallest number among", x,",", y,"and",z,"is: ",min)

smallest(100, 50, 25)
smallest(50, 50, 25)


Output

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