Question

I am trying to read a list,values can be single or it can have multiple entries seperated by a comma,my goal is to append href link for the first value in the list ,col[0] namely,am running into following compilation error

INPUT:-
cols=['409452,  12345', '', '', 'This a test python script']

EXPECTED OUTPUT:-
 <tr>
<td><a href=http://data/409452>409452,<a href=http://data/12345>12345</a></td>
<td></td>
<td></td>
<td>This a test python script</td>

Python code:-

  cols=cols=['409452,  12345', '', '', 'This a test python script']

TEMPLATE = ['  <tr>']
for col in cols:
    value = col.split(",")  
    TEMPLATE.append(
        '    <td><a href=http://data/{}> {}</a></td>'.format(value)
TEMPLATE.append('  </tr>')
TEMPLATE = '\n'.join(TEMPLATE)
print TEMPLATE


Output I am getting:-


TEMPLATE.append('  </tr>')
       ^
SyntaxError: invalid syntax

In addition to the missing ) mentioned by others, your use of format is incorrect (need to use *value to have it look for items in the array). (Your definition of cols also has the wrong indentation and has an extra cols=.)

This code works:

cols=['409452,  12345', '', '', 'This a test python script']

TEMPLATE = ['  <tr>']
for col in cols:
    if "," in col:
        value = col.split(",")
        value[:] = ['<a href=http://data/{0}>{0}</a>'.format(id.strip()) for id in value]
        col = ','.join(value)
    TEMPLATE.append('    <td>{}</td>'.format(col))
TEMPLATE.append('  </tr>')
TEMPLATE = '\n'.join(TEMPLATE)
print TEMPLATE

Output:

  <tr>
    <td><a href=http://data/409452>409452</a>,<a href=http://data/12345>12345</a></td>
    <td></td>
    <td></td>
    <td>This a test python script</td>
 </tr>
