【Python】Excel-4（样式设置）

#练习：
#封装一个ExcelUtil的模块（构造函数是excel的路径），里面提供封装的方法：
#1 获取某个sheet对象
#2 打印所有sheet名称
#3 给某个sheet的某个单元格写入内容
#4 从某个sheet的某个单元读出入内容
#5 保存对excel对象的修改
#6 读取某一行的内容
#7 读取某一列的内容

from openpyxl import Workbook
from openpyxl import load_workbook

class ExcelUtil():
    def __init__(self,path):
        self.path=path
        self.wb=load_workbook(path)
        self.ws=self.wb.active

    #1 获取某个sheet对象
    def get_Excel_sheet(self,sheet_name):
        self.ws=self.wb[sheet_name]

    #2 打印所有sheet名称
    def get_all_sheet(self):
        return self.wb.sheetnames

    #3 给某个sheet的某个单元格写入内容
    def write_sheet(self,row1,column1,value1):
        self.ws.cell(row=row1,column=column1,value=value1)

    #4 从某个sheet的某个单元读出内容
    def read_sheet(self,row1,column1):
        return self.ws.cell(row=row1,column=column1).value

    #5 保存对excel对象的修改
    def save_sheet(self):
        self.wb.save(self.path)

    #6 读取某一行的内容
    def read_row_sheet(self,row_no):
        rows=[]
        for row in self.ws.iter_rows():
            rows.append(row)

        #for cell in rows[row_no-1]:
            #row_content.append(cell.value)
        #return row_content

    #7 读取某一列的内容
    def read_column_sheet(self,col_no):
        cols=[]
        for col in self.ws.iter_cols():
            cols.append(col)

    Excel_obj.get_Excel_sheet("wangjing")

    print Excel_obj.get_all_sheet()

    Excel_obj.write_sheet(2,3,"")

    print Excel_obj.read_sheet(2,3)

    Excel_obj.save_sheet()

    print Excel_obj.read_row_sheet(2)

    print Excel_obj.read_column_sheet(2)
