I got stuck on the part where I have to add the English phone brand to [the] DataFrame.

For instance:

top_10_brands_en = {'华为':'Huawei', '小米':'Xiaomi', '三星':'Samsung', 'vivo':'vivo', 'OPPO':'OPPO', 
                    '魅族':'Meizu', '酷派':'Coolpad', '乐视':'LeEco', '联想':'Lenovo', 'HTC':'HTC'}

df['phone_brand_en'] = df['phone_brand'].apply(lambda phone_brand: top_10_brands_en[phone_brand] if (phone_brand in top_10_brands_en) else 'Other')

There is no clear instruction on how you gathered these specific contents from the phone_brand dataset before storing them in a dictionary.

Please explain to me how you achieved this.

Thank you for your time

IOError: Initializing from file failed
The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

dump() shows all variables in the frame
dump(obj) dumps all that's known about the object
