Python模塊xlwt對excel進行寫入操做

 

 python經常使用模塊目錄

 

一、安裝

$ pip install xlwt

二、建立表格和工做表單寫入內容

例子:

import xlwt
# 建立一個workbook 設置編碼
workbook = xlwt.Workbook(encoding = 'utf-8') #print(workbook) %結果%<xlwt.Workbook.Workbook object at 0x005F4630>
# 建立一個worksheet
worksheet = workbook.add_sheet('小馬過河')

# 寫入excel
# 參數對應 行, 列, 值
worksheet.write(1,0, label = '第二行第一列')

# 保存
workbook.save('學習筆記.xls')
運行後 會在當前目錄生成一個「學習筆記.xls」

三、表格帶帶樣式單元格寫入

import xlwt

workbook = xlwt.Workbook(encoding = 'ascii')
worksheet = workbook.add_sheet('魔降風雲變筆記')
style = xlwt.XFStyle() # 初始化樣式
font = xlwt.Font() # 爲樣式建立字體
font.name = 'Times New Roman'
font.bold = True # 黑體
font.underline = True # 下劃線
font.italic = True # 斜體字
style.font = font # 設定樣式
worksheet.write(0, 0, '不帶樣式的寫入') # 不帶樣式的寫入，第一行第一列
worksheet.write(1, 0, '帶樣式的寫入', style) # 帶樣式的寫入，第二行第一列
workbook.save('個人筆記.xls') # 保存文件

四、設置單元格寬度:

import xlwt

workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('mcw')
worksheet.write(0, 0,'第一行第一列單元格內容')

# 設置單元格寬度
worksheet.col(0).width = 3333
workbook.save('cell_width.xls')

五、輸入一個日期到單元格:

import xlwt
import datetime
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('小馬過河工做表')
style = xlwt.XFStyle()
style.num_format_str = 'M/D/YY' # Other options: D-MMM-YY, D-MMM, MMM-YY, h:mm, h:mm:ss, h:mm, h:mm:ss, M/D/YY h:mm, mm:ss, [h]:mm:ss, mm:ss.0
worksheet.write(0, 0, datetime.datetime.now(), style)
workbook.save('輸入日期.xlsx')

六、向單元格添加一個公式:

import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('測試工做表')
worksheet.write(0, 0, 5) # Outputs 5  #第一行第一列5
worksheet.write(0, 1, 2) # Outputs 2  #第一行第二列2
worksheet.write(1, 0, xlwt.Formula('A1*B1')) # Should output "10" (A1[5] * A2[2])  第二行第一列，輸出第一行數字乘積
worksheet.write(1, 1, xlwt.Formula('SUM(A1,B1)')) # Should output "7" (A1[5] + A2[2])  第二行第二列，輸出第一行數字之和
workbook.save('添加公式並計算.xls')

 

七、向單元格添加一個超連接:

import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('小馬過河')
worksheet.write(0, 0, xlwt.Formula('HYPERLINK("https://www.baidu.com";"百度")')) # 輸出文本百度，爲超連接第一行第一列
workbook.save('添加超連接.xls')

八、合併列和行:

import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('小馬過河')
worksheet.write_merge(0, 1, 0, 3, '合併從第一行到第二行，第一列到第四列') # Merges row 0's columns 0 through 3.
font = xlwt.Font() # Create Font   #建立字體示例
font.bold = True # Set font to Bold  #bold設置爲黑體字
style = xlwt.XFStyle() # Create Style
style.font = font # Add Bold Font to Style
worksheet.write_merge(2,3, 0, 3, '合併從第三行到第四行，第一列到第四列', style) # Merges row 1 through 2's columns 0 through 3.
workbook.save('合併單元格.xls')

九、設置單元格內容的對其方式:

#Alignment n. 結盟; 隊列，排成直線; 校直，調整; [工] 準線;
#HORZ 水平的；地平式;
#GENERAL 廣泛的; 大體的; 綜合的; 總的，全體的;
#FILLED 滿的; 填滿的; 充氣的; 加載的;
#JUSTIFIED adj. 有正當理由的，合理的; 事出有因的;
#DISTRIBUTED 分佈式的;
#VERT n. 森林中的草木，綠色; 傾側; 傾轉;

import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('My Sheet')
alignment = xlwt.Alignment() # 建立對其格式的對象 Create Alignment
alignment.horz = xlwt.Alignment.HORZ_CENTER #我猜是左右的對其，水平居中 May be: HORZ_GENERAL, HORZ_LEFT, HORZ_CENTER, HORZ_RIGHT, HORZ_FILLED, HORZ_JUSTIFIED, HORZ_CENTER_ACROSS_SEL, HORZ_DISTRIBUTED
alignment.vert = xlwt.Alignment.VERT_CENTER #我猜是上下的對其 May be: VERT_TOP, VERT_CENTER, VERT_BOTTOM, VERT_JUSTIFIED, VERT_DISTRIBUTED
style = xlwt.XFStyle() #建立樣式對象 Create Style
style.alignment = alignment # 將格式Alignment對象加入到樣式對象Add Alignment to Style
worksheet.write(0, 0, '單元居中', style)  #寫入的時候調用樣式style
workbook.save('單元格對其方式.xls')
#建立alignment對象，設置單元格上下左右都是居中的。建立樣式對象style，而後將alignment加入到style裏面。在工做表worksheet指定單元格里寫入數據，並使用style樣式

十、爲單元格議添加邊框:

 # Please note: While I was able to find these constants within the source code, on my system (using LibreOffice,) I was only presented with a solid line, varying from thin to thick; no dotted or dashed lines.

import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('小馬過河')
borders = xlwt.Borders()  # 建立邊框對象Create Borders
borders.left = xlwt.Borders.DASHED  #對邊框對象進行操做，指定邊框上下左右的邊框類型爲虛線
# DASHED虛線
# NO_LINE沒有
# THIN實線
# May be: NO_LINE, THIN, MEDIUM, DASHED, DOTTED, THICK, DOUBLE, HAIR, MEDIUM_DASHED, THIN_DASH_DOTTED, MEDIUM_DASH_DOTTED, THIN_DASH_DOT_DOTTED, MEDIUM_DASH_DOT_DOTTED, SLANTED_MEDIUM_DASH_DOTTED, or 0x00 through 0x0D.
borders.right = xlwt.Borders.DASHED
borders.top = xlwt.Borders.DASHED
borders.bottom = xlwt.Borders.DASHED
borders.left_colour = 0x40      #指定上下左右的邊框顏色爲0x40
borders.right_colour = 0x40
borders.top_colour = 0x40
borders.bottom_colour = 0x40
style = xlwt.XFStyle()  # Create Style   #建立樣式對象
style.borders = borders  # 將設置好的邊框對象borders 加到樣式對象style中。Add Borders to Style
worksheet.write(0, 0, '單元格內容', style)   #向單元格第一行第一列寫入「單元格內容」，並使用建立好的樣式對象style
workbook.save('添加邊框.xls')
#建立邊框對象，對邊框對象進行操做，指定邊框上下左右的邊框類型爲虛線等等，指定上下左右的邊框顏色爲0x40。指定上下左右的邊框顏色爲0x40，將設置好的邊框對象borders 加到樣式對象style中。Add Borders to Style，#向單元格第一行第一列寫入「單元格內容」，並使用建立好的樣式對象style

十一、爲單元格設置背景色:

#SOLID 固體; 立體圖形; 立方體;

import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('小馬過河')
pattern = xlwt.Pattern() # 建立模式對象Create the Pattern
pattern.pattern = xlwt.Pattern.SOLID_PATTERN # May be: NO_PATTERN, SOLID_PATTERN, or 0x00 through 0x12
pattern.pattern_fore_colour = 5 #設置模式顏色 May be: 8 through 63. 0 = Black, 1 = White, 2 = Red, 3 = Green, 4 = Blue, 5 = Yellow, 6 = Magenta, 7 = Cyan, 16 = Maroon, 17 = Dark Green, 18 = Dark Blue, 19 = Dark Yellow , almost brown), 20 = Dark Magenta, 21 = Teal, 22 = Light Gray, 23 = Dark Gray, the list goes on...
style = xlwt.XFStyle() # 建立樣式對象Create the Pattern
style.pattern = pattern # 將模式加入到樣式對象Add Pattern to Style
worksheet.write(0, 0, '單元格內容', style)#向單元格寫入內容時使用樣式對象style
workbook.save('設置背景顏色.xls')
