```

## Parameter(s):

The following are the parameter(s):

• number – a valid number to be converted into hexadecimal.

## Python hex() Function: Example 1

```# python code to demonstrate example
# of hex() function

num = 0
print("hex value of ", num, " is = ", hex(num))

num = 10
print("hex value of ", num, " is = ", hex(num))

num = 12345
print("hex value of ", num, " is = ", hex(num))

num = -12345
print("hex value of ", num, " is = ", hex(num))
```

### Output

```hex value of  0  is =  0x0
hex value of  10  is =  0xa
hex value of  12345  is =  0x3039
hex value of  -12345  is =  -0x3039
```

## Python hex() Function: Example 2

If the value is not a valid integer, the program will return a TypeError. Consider the below program:

```# Example to demonstrate the TypeError

x = 10.20
print(hex(x))
```
