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:roman.kiseliov@gmail.com?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

w.add_sheet(u'Item3 is \u00a31.') # RFC2152 example
