Results not opening in browser

[PacoH]

I have installed amzsear 2.0.1 and upgraded pip3 to version 20.2.2. According to Search Amazon Products From Command line - OSTechNix, "you will see the results based on your search string from amazon product directory in your Terminal." and "It will also display the results in your default web browser too." When I run the example amzsear 'Harry Potter Books', despite unfathomable error messages syntax error: A “"” can’t go after this identifier and multiple syntax error: Expected end of line, etc. but found “"”, I get results in terminal but they are not displayed in Firefox.

Is this no longer supported or are the errors the cause or something else?
