Convert RGB to Hex using Python

from webcolors import name_to_hex

def color_name_to_code(color_name):
    try:
        color_code = name_to_hex(color_name)
        return color_code
    except ValueError:
        return None
        
colorname = input("Enter color name : ")
result_code = color_name_to_code(colorname)
print(result_code)

This code snippet converts a color name (like “red” or “blue”) to its hexadecimal color code using Python’s webcolors library. Here's a breakdown:

Importing the Library:

• from webcolors import name_to_hex

This line imports the name_to_hex function from the webcolors library, which allows you to convert color names into their hexadecimal equivalents.

Defining the Function:

• def color_name_to_code(color_name): try: color_code = name_to_hex(color_name) return color_code except ValueError: return None
• color_name_to_code(color_name): This function takes a color_name as input.
• Inside the function, name_to_hex(color_name) is used to convert the color name to its hexadecimal code.
• If the color name is valid, it returns the hexadecimal color code.
• If the color name is invalid (e.g., “lightblue”), name_to_hex raises a ValueError, which the except block catches, returning None instead.

User Input and Function Call:

• colorname = input("Enter color name : ") result_code = color_name_to_code(colorname) print(result_code)
• The user is prompted to enter a color name.
• The color_name_to_code function is called with the user’s input, and the result is printed.
