操作excel安装的三种方式:
1、pip install xlwt #写excel
pip install xlrd #读excel
pip install xlutils #修改excel
2、.whl
pip install c:/user/niuhanyang/desktop/xxx.whl
3、.tar.gz
1、先解压
2、解压之后在命令行里面进入到这个目录下
3、执行python setup.py install
4、如果安装多个python版本
python3.5 -m pip instaill XXX
python2 -m pip instail XXX
python3.6 -m pip instail XXX
一、写excel
import xlwt
import xlrd
import xlutils
# 写excel
book=xlwt.Workbook()
sheet=book.add_sheet('sheet1')
# sheet.write(0,0,'id') #指定行和列内容
# sheet.write(0,1,'username')
# sheet.write(0,2,'password')
#
# sheet.write(1,0,'1')
# sheet.write(1,1,'niuhanyang')
# sheet.write(1,2,'123456')
stus=[
[1,'njf','1234'],
[2,'njf1','1234'],
[3,'njf2','1234'],
[4,'njf3','1234'],
[5,'njf4','1234'],
[6,'njf5','1234'],
[7,'njf6','1234'],
[8,'njf7','1234'],
[9,'njf8','1234'],
[10,'njf9','1234'],
]
line=0 #控制的是行
for stu in stus:
col=0
for s in stu:
sheet.write(line,col,s)
col+=1
line+=1
book.save('stu.xls')
二、读excel
import xlrd
book=xlrd.open_workbook('stu.xls')
sheet=book.sheet_by_index(0) #根据sheet编号来
# sheet=book.sheet_by_name('sheet1') #根据 sheet名称来
print(sheet.nrows) #excel里面有多少行
print(sheet.ncols) #excel里面有多少列
print(sheet.cell(0,0).value) #获取第0行第0列的值
print(sheet.row_values(0)) #获取到整行的内容
print(sheet.col_values(0)) #获取到整列的内容
for i in range(sheet.nrows): #循环获取每行的内容
print(sheet.row_values(i))
三、修改excel
import xlrd
import xlutils
from xlutils import copy #xlutils中导入copy
book=xlrd.open_workbook('stu.xls')
#先用xlrd打开一个excel
new_book=copy.copy(book)
#然后用xlutils里面的copy功能,复制一个excel
sheet=new_book.get_sheet(0) #获取sheet页
sheet.write(0,1,'张三') #修改第0行,第一列
sheet.write(1,1,'小军') #修改第一行,第一列
new_book.save('stu.xls')
