# Python: Convert a hexadecimal color code to its RGB components

## Python String: Exercise-94 with Solution

Write a Python program to convert a hexadecimal color code to a tuple of integers corresponding to its RGB components.

• Use a list comprehension in combination with int() and list slice notation to get the RGB components from the hexadecimal string.
• Use tuple() to convert the resulting list to a tuple.

Sample Solution:

Python Code:

``````def hex_to_rgb(hex):
return tuple(int(hex[i:i+2], 16) for i in (0, 2, 4))
print(hex_to_rgb('FFA501'))
print(hex_to_rgb('FFFFFF'))
print(hex_to_rgb('000000'))
print(hex_to_rgb('FF0000'))
print(hex_to_rgb('000080'))
print(hex_to_rgb('C0C0C0'))
```
```

Sample Output:

```(255, 165, 1)
(255, 255, 255)
(0, 0, 0)
(255, 0, 0)
(0, 0, 128)
(192, 192, 192)
```

## Python: Tips of the Day

What is the difference between Python's list methods append and extend?

append: Appends object at the end.

```x = [1, 2, 3]
x.append([4, 5])
print (x)
```

Output:

```[1, 2, 3, [4, 5]]
```

extend: Extends list by appending elements from the iterable.

```x = [1, 2, 3]
x.extend([4, 5])
print (x)
```

Output:

```[1, 2, 3, 4, 5]
```
