I have a question regarding overwriting multiple variables in python-CodePudding

In a program, I'm writing for a school project where you basically pick your subjects and the colours that you want each of those subjects to be. I have multiple variables which represent colours, but I want to overwrite them with hex values I've set. How would I do this without writing a hundred "if statements".

For reference here is the code I've currently got and trying to find a solution for:

LangColour = parser.get('Colour', 'lang')
HmtColour = parser.get('Colour', 'hmt')
SciColour = parser.get('Colour', 'sci')
ArtColour = parser.get('Colour', 'art')
MathColour = parser.get('Colour', 'math')
EngColour = parser.get('Colour', 'eng')

Red = '#ff6666'
Orange = '#ff9966'
Yellow = '#ffff66'
Green = '#99ff99'
DarkBlue = '#99ccff'
LightBlue = '#99ffff'
Pink = '#ff99ff'
Purple = '#cc99ff'
Grey = '#bcbcbc'

And the values for parser.get are being pulled from a .ini file:

[Colour]
lang = Dark Blue
hmt = Orange
sci = Pink
art = Green
math = Light Blue
eng = Red

I have no idea what to do, I'm relatively inexperienced so I'm really not sure what I can try. I've tried searching it up, and the main results were to write "if statements" which is what I'd like to avoid as I feel there's probably a better way to do it.

CodePudding user response：

You can use a dictionary to map the string values from the .ini file to the corresponding hex values.

Create a dictionary with the keys being the string values from the .ini file and the values being the corresponding hex values. Then, you can use the dictionary to assign the hex values to the variables.

For example:

 hex_colors = {
'Dark Blue': '#99ccff',
'Orange': '#ff9966',
'Pink': '#ff99ff',
'Green': '#99ff99',
'Light Blue': '#99ffff',
'Red': '#ff6666'
    }

LangColour = hex_colors[parser.get('Colour', 'lang')]
HmtColour = hex_colors[parser.get('Colour', 'hmt')]
SciColour = hex_colors[parser.get('Colour', 'sci')]
ArtColour = hex_colors[parser.get('Colour', 'art')]
MathColour = hex_colors[parser.get('Colour', 'math')]
EngColour = hex_colors[parser.get('Colour', 'eng')]

This way you don't need to write 100 if statements and it's more readable and easy to maintain.
