python linux读写excel

hich turned out to be pretty popular) I showed you how to read
Excel files with Python. Now for the reverse: writing Excel
files.
First, you’ll need to install the
xlwt package by John
Machin.
The basics
In order to write data to an Excel spreadsheet, first you have to
initialize a Workbook object and then add a Worksheet object to
that Workbook. It goes something like this:
import xlwt
wbk = xlwt.Workbook()
sheet =
wbk.add_sheet('sheet
1')
|
Now that the sheet is created, it’s very easy to write data to
it.
# indexing is zero based, row then column
sheet.write(0,1,'test
text')
|
When you’re done, save the workbook (you don’t have to close it
like you do with a file object)
Digging deeper
Overwriting cells
Worksheet objects, by default, give you a warning when you try to
overwrite:
sheet.write(0,0,'test')
sheet.write(0,0,'oops')
# returns error:
# Exception: Attempt to overwrite cell: sheetname=u'sheet 1'
rowx=0 colx=0
|
To change this behavior, use the
cell_overwrite_ok=True kwarg when
creating the worksheet, like so:
sheet2 =
wbk.add_sheet('sheet 2',
cell_overwrite_ok=True)
sheet2.write(0,0,'some
text')
sheet2.write(0,0,'this
should overwrite')
|
Now you can overwrite sheet 2 (but not sheet 1).
More goodies
# Initialize a style
style = xlwt.XFStyle()
# Create a font to use with the style
font = xlwt.Font()
font.name = 'Times New
Roman'
font.bold = True
# Set the style's font to this new one you set
up
style.font = font
# Use the style when writing
sheet.write(0,
0, 'some bold Times
text', style)
