问题:

I've noticed that Github picked JavaScript as the language for my Django app:

Is it possible to change it to Python? Or do I need to make a new repository?

Solved:

As @Geno Chen said, to change the repository language we have to add the file .gitattributes containing this code:

# to change language of repo from Javascript to Python
    *.js linguist-language=Python

回答1:

The language detector stats the programs in your projects and shows the result with the ratio. If your repository have detected a wrong language, you can follow the tutorial, most of the time you just need to override the result with a .gitattributes in the repository root containing something like the sample from tutorial, to manually pull up the ratio of specific programming language:

# Example of a `.gitattributes` file which reclassifies `.rb` files as Java:
*.rb linguist-language=Java

Create a new file in your repo and name it to .gitattributes. After that make sure you set linguist-detectable to truelike this:

*.css linguist-detectable=false
*.java linguist-detectable=false
*.python linguist-detectable=true 
*.js linguist-detectable=false
*.html linguist-detectable=false  
*.xml linguist-detectable=false
