Now i want to display the output in html table.

html_str='<table border=1>' 
for row in res: 
    html_str=html_str+'<tr>' 
    for col in row: 
     html_str=html_str+'<td>'+str(col) 
     html_str=html_str+'</td>' 
    html_str=html_str+'</tr>' 

html_str=html_str+'</table>' 
myhtml=open('f:\\test.html','w') 
myhtml.write(html_str) 
myhtml.close() 
os.system('"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" f:\\test.html') 

I want to improve my code
1.to simplify the creation of html file.
2.it is stupid to open the test.html file with
os.system('"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" f:\\test.html')

How can i display it with temple jinjia2 more elegantly?

Answer 1

Make a template with jinja2.Template :

import jinja2 

template = jinja2.Template(''' 
<table border=1> 
{% for row in res %} 
    <tr> 
    {% for col in row -%} 
     <td>{{ col|replace('\s', ':1,7>') }}</td> 
    {% endfor %} 
    </tr> 
{% endfor %} 
</table> 
''') 

Render the template with jinja2.Template.render (with res passed), then write it to file:

with open('test.html', 'w') as f: 
    f.write(template.render(res=res)) 

To open the file in browser, use webbrowser.open (It will use the default web browser):

import webbrowser 
webbrowser.open('test.html')
