【Python】Excel操作-1

#练习：创建Excel 如果要创建的Excel已经存在并打开，会报错
from openpyxl import Workbook
wb=Workbook()    #创建文件对象

ws=wb.active    #获取第一个sheet
ws["A1"]=22     #写入数字

ws["B1"]="王某某"+"automation test"  #写入中文
ws.append([1,2,3])    #写入多个单元格,一行

import datetime
import time
ws["A2"]=datetime.datetime.now()    #写入一个当前时间
ws["A3"]=time.strftime("%Y%m%d %H%M%S",time.localtime()) #写入一个自定义的时间格式

#在Excel中写入100个数字
#方法一：
for i in range(100):
    ws.append(i)

#方法二：
x=1
data=map(lambda x:"A"+str(x),range(1,101))
for i in data:
    ws[i]=x
    x+=1

wb.save("e:\test4\sample.xlsx") #保存Excel




#练习：
from openpyxl import Workbook
wb = Workbook()

ws1 = wb.create_sheet("Mysheet",0)           #创建一个sheet
ws1.title = "New Title"                    #设定一个sheet的名字
ws2 = wb.create_sheet("Mysheet", 1)        #设定sheet的插入位置
ws2.title = u"王某某"    #设定一个sheet的名字

ws1.sheet_properties.tabColor = "1072BA"   #设定sheet的标签的背景颜色

#获取某个sheet对象
print wb["New Title" ]

#获取全部sheet 的名字，遍历sheet名字
print wb.sheetnames
for sheet_name in wb.sheetnames:
    print sheet_name

print "*"*50

for sheet in wb:
    print sheet.title

#复制一个sheet
wb["New Title" ]["A1"]=u"哈哈哈哈"
source = wb["New Title" ]
target = wb.copy_worksheet(source)

#target=wb.copy_worksheet(wb["new title"])

# Save the file
wb.save("e:\sample.xlsx")


#练习：#生成一个excel文件，生成3个sheet，名称包含中文,每个sheet的a1写一下sheet的名称。每个sheet有个底色
