Xlrd是跨平臺的excel生成模塊。
31.1 xlwt– 實例
31.1.1 創(chuàng)建簡單的excel文件
下面例子，創(chuàng)建一個名為mini.xls的文件，它有一個空sheet：'xlwt was here'。
from xlwt import *
?
w = Workbook()
ws = w.add_sheet('xlwt was here')
w.save('mini.xls')
Workbook類初始化時有encoding和style_compression參數。
encoding，設置字符編碼，一般要這樣設置：w = Workbook(encoding='utf-8')，就可以在excel中輸出中文了。默認是ascii。當然要記得在文件頭部添加：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
style_compression表示是否壓縮，不常用。
Workbook還有一些屬性：
Owner設置文檔所有者。
country_code：國家碼
wnd_protect：窗口保護
obj_protect：對象保護
Protect：保護
backup_on_save：保存時備份
Hpos：橫坐標
Vpos：縱坐標
Width：寬度
Height：高度
active_sheet：活動sheet
tab_width：tab寬度
wnd_visible：窗口是否可見
wnd_mini：窗口最小化
hscroll_visible：橫向滾動條是否可見。
vscroll_visible：縱向滾動條是否可見。
tabs_visible：tab是否可見。
dates_1904：是否使用1904日期系統(tǒng)
use_cell_values：單元格的值
default_style：默認樣式
colour_RGB：顏色
比如設置國家碼：
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 插入圖片
add_sheet 會返回一個Worksheet 類。創(chuàng)建的時候有可選參數cell_overwrite_ok，表示是否可以覆蓋單元格，其實是Worksheet實例化的一個參數，默認值是False。
Worksheet初始化的參數有sheetname，parent_book，cell_overwrite_ok。
Worksheet的屬性有：Row，Column，explicit_magn_setting（默認False），visibility（默認0），split_position_units_are_twips（默認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。以上屬性類定義中。
函數構成的屬性有：name，parent（只讀），rows（只讀），cols（只讀），merged_ranges（只讀），bmp_rec（只讀），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來插入圖片。
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 設置樣式
下面例子改變字體的高度。
?
#!/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, '武岡')
??? ws.row(i).set_style(style)
w.save('row_styles.xls')
?????????????? XFStyle用于設置字體樣式，有描述字符串num_format_str，字體font，居中alignment，邊界borders，模式pattern，保護protection等屬性。另外還可以不寫單元格，直接設置格式，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')
??????????????? 設置列寬：ws.col(i).width = 0x0d00 + i
31.1.4 更多實例
下面例子輸出了紅色的”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')
這里另有一個公式的實例：
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)""")
合并單元格的實例，注意write_merge,1,2個參數表示行數，3,4的參數表示列數。
?
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')
日期格式的實例
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')
?
下面展示了不同邊框和刪除樣式的字體：
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')

?
??? ws0.write(i, 2,'colour', style)
??? ws0.write(i, 3,hex(i), style0)
?
?
wb.save('format.xls')
超級鏈接的插入方法：
?
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')

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)

??????? 在沒有指定編碼的情況下，也可以通過unicode輸出字符，不過這樣比較費勁，建議還是使用utf-8編碼：

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

#Write an XLS file with a single worksheet, containing
#a heading row and some rows of data.
