# hex()

``hex(number)``
number :input integer number
Return the hexal number as string.

## Examples

``````my_num=27
print(hex(my_num))  # 0x1b``````

## Using Float

This will generate TypeError
``````num=27.45
print(hex(num))``````
TypeError: 'float' object cannot be interpreted as an integer

## Binary to hex

``print(hex(0b11011)) # 0x1b``
In above code the input binary number is equivalent to integer 27.

You can use bin() to get the binary output
``print("Binary Number : ", bin(27)) # Binary Number :  0b11011``

## octal to hex

``print(hex(0o33)) # 0x1b``
In above code the input Octal number is equivalent to integer 27 You can use oct() to get the Octal output
``print("Octal  Number : ", oct(27)) # Octal  Number :  0o33``
In our hex output, `0x` is always prefixed. As the output is a string we can remove it like this
``````my_hex=hex(27)
print(my_hex[2:]) # 1b``````
Without using hex() and by using format()
``````my_num=27
print(format(my_num,'x')) # 1b``````

## Hex code for Colors

Hexadecimal (hex) color codes are a way to represent colors in a format that uses a combination of letters and numbers. Each color is represented by a six-digit code that consists of three pairs of two characters each. These pairs represent the intensity of red, green, and blue components of the color. Here's how the hex code works:
1. The first two characters represent the red component.
2. The next two characters represent the green component.
3. The last two characters represent the blue component.
For example:
• The hex code #FF0000 represents pure red (maximum red, no green, no blue).
• The hex code #00FF00 represents pure green (no red, maximum green, no blue).
• The hex code #0000FF represents pure blue (no red, no green, maximum blue).
From HEX code to RGB ( Red Green Blue ) values.
The commented part can be used to get the return value as Tuple for further processing.
``````def hex_to_rgb(hex):
#rgb = []
str1='RGB('
for i in (0, 2, 4):
#decimal = int(hex[i:i+2], 16)
str1=str1+str(int(hex[i:i+2],16))+','
#rgb.append(decimal)
#return tuple(rgb)
str1=str1.rstrip(',')+")"
return str1
print(hex_to_rgb('#FF65AA'.lstrip('#'))) # Output RGB(255,101,170)``````
