First, the basic concepts
in Excel mainly related to three concepts: Workbooks, Sheets, Cells. Wherein excel sheet is a Workbook; Sheet worksheet is a page table; Cell is a simple grid. Usually read and write Excel substantially three steps as follows: Open Workbook, positioning Sheet, operation Cell. Read and write the following points were introduced a few common approach of python.
Second, write Excel
Here we use a case study to demonstrate the process of Python written in Excel. A simulated student information, student information is written to an Excel file.
————————————————
Import library xlwt
Import xlwt
. 1
without xlwt library, then the library can be used to import pip:
the install xlwt PIP
. 1
acquires a Workbook, to set the encoding set "UTF-. 8"
work_book = xlwt.Workbook (encoding = "UTF-. 8")
. 1
generates a Sheet Workbooks in the
Worksheet = work_book.add_sheet (SHEET_NAME)
. 1
recording write into the cell
# row representing lines, COL for column, data representative of the contents to fill
worksheet.write (row, COL, data)
. 1
2
save to save the file in the Workbook
work_book.save (self.filename)
. 1
Third, styling
However, in the actual scene, far more than the production of Excel data is written so simple, sometimes in order to achieve beautiful, it involves complex table style. E.g:
Set the font, font size, font color, text placement, bold, italic, etc.
merge cells, rows, merge, merge column, and region merging
set the background color
to set the border properties
set the line width
below us one by one to demonstrate how to set the table style
Set the font
style = xlwt.XFStyle () # initialize style
font = xlwt.Font () # create the font style
font.name = "blackbody" # set the font to "black body", the default is "Arial"
font.height = 100 # set the font size to 100, the default is 200
. Font.Bold = True # whether the font is bold
font.underline = True # underscore
font.italic = True # italics
style.font = font # styled
worksheet.write (row, col, data, style) # write pattern data tape
. 1
2
. 3
. 4
. 5
. 6
. 7
. 8
. 9
merged cell are consolidated, and the combined column region merging
# merge from (0,0) to the cell (0,2) unit cells, cells of the first row and three merged cell
worksheet.write_merge (0, 0, 0, 2, "Hello World")
# line combined with other styles and
worksheet.write_merge (0, 0, 0, 2, "Hello World", style)
# merge from (0,0) to the cell (2,0) cells and three cells in the first column were combined
worksheet.write_merge (0, 0, 2, 0, "Hello World")
# merge from (0,0) to the cell (2,2) cells, and merging the first row 3 of 9 * 3 cells region
worksheet.write_merge (0, 0, 2, 2, "Hello World")

set the background color
pattern = xlwt.Pattern () # example of a style class
pattern.pattern = xlwt.Pattern .SOLID_PATTERN # fixed pattern
pattern.pattern_fore_colour = xlwt.Style.colour_map [ 'yellow'] # background color
style.pattern = pattern
worksheet.write (Row, COL, data, style) # write pattern data tape

set the border attribute
borders = xlwt.Borders () # to create the border style, border no default
borders.left = 1 # set left border width. 1
borders.right. 1 =
borders.top. 1 =
=. 1 borders.bottom
style.borders = Borders
worksheet.write (Row, COL, Data, style) # write pattern data tape

. 3
. 4

. 7
setting the line width of
the width of the column provided #
worksheet.col (i ) .width = 150 * 30

Here we demonstrate an actual case, use the form below xlwt library written information:
