Body
Python methods can return only one result at a time. That one result can be a list of lists; just return a larger list, and loop over the result: <pre><code>result = [] row2 = [] while curr_row < numOfRows: curr_row += 1 row2 = [] row = worksheet.row(curr_row) for value2 in re.findall(r"'(.*?)'", str(row)): row2.append(value2) result.append(row2) return result </code></pre> and: <pre><code>for row in Classobject.collectInfoFromXLS(): print row </code></pre> A more advanced technique would be to turn your method into a generator function, and yield the rows, one by one. You'd still loop over the method. To make the function a generator, use a <code>yield</code> expression; you can no longer use <code>return</code> with a value once you make it a generator: <pre><code>def collectInfoFromXLS(): workbookPath = config.get('TestCaseFileURL','XLSpath') workbook = xlrd.open_workbook(workbookPath) SheetPath = config.get('TesCaseSheetName','Sheet1') worksheet = workbook.sheet_by_name(SheetPath) numOfRows = worksheet.nrows - 1 curr_row = 0 row2 = [] while curr_row < numOfRows: curr_row += 1 row2 = [] row = worksheet.row(curr_row) for value2 in re.findall(r"'(.*?)'", str(row)): row2.append(value2) yield row2 </code></pre> You still have to loop over the output: <pre><code>for row in Classobject.collectInfoFromXLS(): print row </code></pre> only now <code>Classobject.collectInfoFromXLS()</code> returns a generator object instead of a list, and you can loop over that object only once.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
