Converts the values of RGB components to a hexadecimal color code.
|
|
|
|
- Create a placeholder for a zero-padded hexadecimal value using `'{:02X}'` and copy it three times.
|
|
- Use `str.format()` on the resulting string to replace the placeholders with the given values.
|
|
|
|
```py
|
|
def rgb_to_hex(r, g, b):
|
|
return ('{:02X}' * 3).format(r, g, b)
|
|
```
|
|
|
|
```py
|
|
rgb_to_hex(255, 165, 1) # 'FFA501'
|
|
```
