xlsxwriter expected an indented block
Question: After spending some time to compile
[libxlsxwriter](http://libxlsxwriter.github.io/) as a dylib for osx without
success, I made the decision to switch to NSTask using the Python module
[XlsxWriter](http://xlsxwriter.readthedocs.org/). But another problem come
out: indentation! I want to achieve iteration through an array and put each
value in a row and column programmatically. However I am struggling with this
example from the docs:

    
    
    import xlsxwriter. 
    
    # Create a workbook and add a worksheet.
    workbook = xlsxwriter.Workbook('Expenses01.xlsx')
    worksheet = workbook.add_worksheet()
    
    # Some data we want to write to the worksheet.
     expenses = (
    ['Rent', 1000],
    ['Gas',   100],
    ['Food',  300],
    ['Gym',    50],
    )
    
    # Start from the first cell. Rows and columns are zero indexed.
    row = 0
    col = 0
    
    # Iterate over the data and write it out row by row.
    for item, cost in (expenses):
    worksheet.write(row, col,     item) #LINE 21 <---
    worksheet.write(row, col + 1, cost)
    row += 1
    # Write a total using a formula.
    worksheet.write(row, 0, 'Total')
    worksheet.write(row, 1, '=SUM(B1:B4)')
    
    workbook.close()
    

OUTPUT

    
    
    File "test.py", line 21
    worksheet.write(row, col,     item)
            ^
    IndentationError: expected an indented block
    


Answer: XlsxWriter doesn't expect the block to be indented, Python does.

You will need to indent the code as shown in the original [example that the
code above was taken from](http://libxlsxwriter.github.io/tutorial01.html).
