# 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.

### Method 1: Using If statement

In the example below, 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)
```

The above code will give the following output:

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

### Method 2: 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)
```

The above code will give the following output:

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

### Method 3: 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)
```

The above code will give the following output:

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

### Method 4: 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)
```

The above code will give the following output:

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