I am trying to import only .py and .json file, and passing accept as
text/x-python-script, application/json, text/x-python
In windows OS, only .json files are able to get imported not the python file.
Pass the filename extension for python files instead of the MIME type
<input type="file" accept="application/json,.py" />
