Xlrd是跨平台的excel生成模块。

31.1 xlwt– 实例

31.1.1 创建简单的excel文件

下面例子，创建一个名为mini.xls的文件，它有一个空sheet：'xlwt was here'。

from xlwt import *

 

w = Workbook()

ws = w.add_sheet('xlwt was here')

w.save('mini.xls')

Workbook类初始化时有encoding和style_compression参数。

encoding，设置字符编码，一般要这样设置：w = Workbook(encoding='utf-8')，就可以在excel中输出中文了。默认是ascii。当然要记得在文件头部添加：

#!/usr/bin/env python

# -*- coding: utf-8 -*-

style_compression表示是否压缩，不常用。

Workbook还有一些属性：

Owner设置文档所有者。

country_code：国家码

wnd_protect：窗口保护

obj_protect：对象保护

Protect：保护

backup_on_save：保存时备份

Hpos：横坐标

Vpos：纵坐标

Width：宽度

Height：高度

active_sheet：活动sheet

tab_width：tab宽度

wnd_visible：窗口是否可见

wnd_mini：窗口最小化

hscroll_visible：横向滚动条是否可见。

vscroll_visible：纵向滚动条是否可见。

tabs_visible：tab是否可见。

dates_1904：是否使用1904日期系统

use_cell_values：单元格的值

default_style：默认样式

colour_RGB：颜色

比如设置国家码：

fromxlwt import *

 

w= Workbook()

w.country_code= 61

ws= w.add_sheet('AU')

w.save('country.xls')

方法有：add_style，add_font，add_str，del_str，str_index，add_rt，rt_index，add_sheet，get_sheet，raise_bad_sheetname，convert_sheetindex，setup_xcall，add_sheet_reference。

31.1.2 插入图片

add_sheet 会返回一个Worksheet 类。创建的时候有可选参数cell_overwrite_ok，表示是否可以覆盖单元格，其实是Worksheet实例化的一个参数，默认值是False。

Worksheet初始化的参数有sheetname，parent_book，cell_overwrite_ok。

Worksheet的属性有：Row，Column，explicit_magn_setting（默认False），visibility（默认0），split_position_units_are_twips（默认False），row_default_height_mismatch，row_default_hidden，row_default_space_above，row_default_space_below，last_used_row，first_used_row，last_used_col，row_tempfile。以上属性类定义中。

函数构成的属性有：name，parent（只读），rows（只读），cols（只读），merged_ranges（只读），bmp_rec（只读），show_formulas，show_grid，show_headers，panes_frozen，auto_colour_grid，cols_right_to_left，show_outline，remove_splits，selected，sheet_visible，page_preview，first_visible_row，first_visible_col，grid_colour，preview_magn，normal_magn，scl_magn，vert_split_pos，horz_split_pos，vert_split_first_visible，horz_split_first_visible，show_auto_page_breaks，dialogue_sheet，auto_style_outline，outline_below，outline_right，fit_num_pages，show_row_outline，show_col_outline，alt_expr_eval，alt_formula_entries，row_default_height，col_default_width，calc_mode，calc_count，RC_ref_mode，iterations_on，delta，save_recalc，print_headers，print_grid，vert_page_breaks，horz_page_breaks，header_str，footer_str，print_centered_vert，print_centered_horz，left_margin，right_margin，top_margin，bottom_margin，paper_size_code，print_scaling，start_page_number，fit_width_to_pages，fit_height_to_pages，print_in_rows，portrait，print_colour，print_draft，print_notes，print_notes_at_end，print_omit_errors，print_hres，print_vres，header_margin，footer_margin，copies_num，wnd_protect，obj_protect，protect，scen_protect，password。

方法有：get_parent，write，write_rich_text，merge，write_merge，insert_bitmap，col，row，row_height，col_width。

下面例子使用 insert_bitmap来插入图片。

from xlwt import *，

 

w = Workbook()

ws = w.add_sheet('Image')

ws.insert_bitmap('python.bmp', 2, 2)

ws.insert_bitmap('python.bmp', 10, 2)

 

w.save('image.xls')

31.1.3 设置样式

下面例子改变字体的高度。

 

#!/usr/bin/envpython

#-*- coding: utf-8 -*-

#Copyright (C) 2005 Kiseliov Roman

 

fromxlwt import *

 

w= Workbook(encoding='utf-8')

ws= w.add_sheet('Hey, Dude')

 

fori in range(6, 80):

    fnt = Font()

    fnt.height = i*20

    style = XFStyle()

    style.font = fnt

    ws.write(i, 1, '武冈')

    ws.row(i).set_style(style)

w.save('row_styles.xls')

               XFStyle用于设置字体样式，有描述字符串num_format_str，字体font，居中alignment，边界borders，模式pattern，保护protection等属性。另外还可以不写单元格，直接设置格式，比如：

frompyExcelerator import *

 

w= Workbook()

ws= w.add_sheet('Hey, Dude')

 

fori in range(6, 80):

    fnt = Font()

    fnt.height = i*20

    style = XFStyle()

    style.font = fnt

    ws.row(i).set_style(style)

w.save('row_styles_empty.xls')

                设置列宽：ws.col(i).width = 0x0d00 + i

31.1.4 更多实例

下面例子输出了红色的”Test”，并在第3行包含了公式。

importxlwt

fromdatetime import datetime

 

font0= xlwt.Font()

font0.name= 'Times New Roman'

font0.colour_index= 2

font0.bold= True

 

style0= xlwt.XFStyle()

style0.font= font0

 

style1= xlwt.XFStyle()

style1.num_format_str= 'D-MMM-YY'

 

wb= xlwt.Workbook()

ws= wb.add_sheet('A Test Sheet')

 

ws.write(0,0, 'Test', style0)

ws.write(1,0, datetime.now(), style1)

ws.write(2,0, 1)

ws.write(2,1, 1)

ws.write(2,2, xlwt.Formula("A3+B3"))

 

wb.save('example.xls')

这里另有一个公式的实例：

fromxlwt import ExcelFormulaParser, ExcelFormula

importsys

 

f= ExcelFormula.Formula(

"""-((1.80 + 2.898 * 1)/(1.80 + 2.898))*

AVERAGE((1.80+ 2.898 * 1)/(1.80 + 2.898);

        (1.80 + 2.898 * 1)/(1.80 + 2.898);

        (1.80 + 2.898 * 1)/(1.80 + 2.898)) +

SIN(PI()/4)""")

合并单元格的实例，注意write_merge,1,2个参数表示行数，3,4的参数表示列数。

 

fromxlwt import *

 

wb= Workbook()

ws0= wb.add_sheet('sheet0')

 

 

fnt= Font()

fnt.name= 'Arial'

fnt.colour_index= 4

fnt.bold= True

 

borders= Borders()

borders.left= 6

borders.right= 6

borders.top= 6

borders.bottom= 6

 

style= XFStyle()

style.font= fnt

style.borders = borders

 

ws0.write_merge(3,3, 1, 5, 'test1', style)

ws0.write_merge(4,10, 1, 5, 'test2', style)

ws0.col(1).width= 0x0d00

 

wb.save('merged0.xls')

日期格式的实例

fromxlwt import *

fromdatetime import datetime

 

w= Workbook()

ws= w.add_sheet('Hey, Dude')

 

fmts= [

    'M/D/YY',

    'D-MMM-YY',

    'D-MMM',

    'MMM-YY',

    'h:mm AM/PM',

    'h:mm:ss AM/PM',

    'h:mm',

    'h:mm:ss',

    'M/D/YY h:mm',

    'mm:ss',

    '[h]:mm:ss',

    'mm:ss.0',

]

 

i= 0

forfmt in fmts:

    ws.write(i, 0, fmt)

 

    style = XFStyle()

    style.num_format_str = fmt

 

    ws.write(i, 4, datetime.now(), style)

 

    i += 1

 

w.save('dates.xls')

 

下面展示了不同边框和删除样式的字体：

fromxlwt import *

 

font0= Font()

font0.name= 'Times New Roman'

font0.struck_out= True

font0.bold= True

 

style0= XFStyle()

style0.font= font0

 

 

wb= Workbook()

ws0= wb.add_sheet('0')

 

ws0.write(1,1, 'Test', style0)

 

fori in range(0, 0x53):

    borders = Borders()

    borders.left = i

    borders.right = i

    borders.top = i

    borders.bottom = i

 

    style = XFStyle()

    style.borders = borders

 

    ws0.write(i, 2, '', style)

    ws0.write(i, 3, hex(i), style0)

 

ws0.write_merge(5,8, 6, 10, "")

 

wb.save('blanks.xls')

 

 

下面展示了不同颜色的字体，可以作为颜色参考：

 

from xlwt import *

 

font0 = Font()

font0.name = 'Times New Roman'

font0.struck_out = True

font0.bold = True

 

style0 = XFStyle()

style0.font = font0

 

 

wb = Workbook()

ws0 = wb.add_sheet('0')

 

ws0.write(1, 1, 'Test', style0)

 

for i in range(0, 0x53):

    fnt = Font()

    fnt.name = 'Arial'

    fnt.colour_index = i

    fnt.outline = True

 

    borders = Borders()

    borders.left = i

 

    style = XFStyle()

    style.font = fnt

    style.borders =borders

 

    ws0.write(i, 2,'colour', style)

    ws0.write(i, 3,hex(i), style0)

 

 

wb.save('format.xls')

超级链接的插入方法：

 

fromxlwt import *

 

f= Font()

f.height= 20*72

f.name= 'Verdana'

f.bold= True

f.underline= Font.UNDERLINE_DOUBLE

f.colour_index= 4

 

h_style= XFStyle()

h_style.font= f

 

w= Workbook()

ws= w.add_sheet('F')

 

##############

##NOTE: parameters are separated by semicolon!!!

##############

 

n= "HYPERLINK"

ws.write_merge(1,1, 1, 10, Formula(n +'("http://www.irs.gov/pub/irs-pdf/f1000.pdf";"f1000.pdf")'),h_style)

ws.write_merge(2,2, 2, 25, Formula(n +'("mailto:[email protected]?subject=pyExcelerator-feedback&Body=Hello,%20Roman!";"pyExcelerator-feedback")'),h_style)

 

w.save("hyperlinks.xls")

 

        在没有指定编码的情况下，也可以通过unicode输出字符，不过这样比较费劲，建议还是使用utf-8编码：

 

fromxlwt import *

 

w= Workbook()

ws1= w.add_sheet(u'\N{GREEK SMALL LETTER ALPHA}\N{GREEK SMALL LETTER BETA}\N{GREEKSMALL LETTER GAMMA}')

 

ws1.write(0,0, u'\N{GREEK SMALL LETTER ALPHA}\N{GREEK SMALL LETTER BETA}\N{GREEK SMALLLETTER GAMMA}')

ws1.write(1,1, u'\N{GREEK SMALL LETTER DELTA}x = 1 + \N{GREEK SMALL LETTER DELTA}')

 

ws1.write(2,0,u'A\u2262\u0391.')     # RFC2152 example

ws1.write(3,0,u'Hi Mom -\u263a-!')   # RFC2152 example

ws1.write(4,0,u'\u65E5\u672C\u8A9E') # RFC2152 example

ws1.write(5,0,u'Item 3 is \u00a31.') # RFC2152 example

ws1.write(8,0,u'\N{INTEGRAL}')       # RFC2152 example

 

w.add_sheet(u'A\u2262\u0391.')     # RFC2152 example

w.add_sheet(u'HiMom -\u263a-!')   # RFC2152 example

one_more_ws= w.add_sheet(u'\u65E5\u672C\u8A9E') # RFC2152 example

31.1.5 完整实例

下面程序的write_xls对输出xls进行了一定封装，比较有实用意义。

#Write an XLS file with a single worksheet, containing

#a heading row and some rows of data.

 

importxlwt

importdatetime

defwrite_xls(file_name,sheet_name, headings, data, heading_xf, data_xfs):

    book = xlwt.Workbook()

    sheet = book.add_sheet(sheet_name)

    rowx = 0

    for colx, value in enumerate(headings):

        sheet.write(rowx, colx, value,heading_xf)

    sheet.set_panes_frozen(True) # frozenheadings instead of split panes

    sheet.set_horz_split_pos(rowx+1) # ingeneral, freeze after last heading row

    sheet.set_remove_splits(True) # if userdoes unfreeze, don't leave a split there

    for row in data:
