Python2-openpyxl对Excel的操作（获取总行列数，获取某行值，获取某列值，设置单元格值）

from openpyxl import *

class excel():
    def __init__(self,file):
        self.file = file
        self.wb = load_workbook(self.file)
        sheets = self.wb.get_sheet_names()
        self.sheet = sheets[0]
        self.ws = self.wb[self.sheet]
        
    #获取表格的总行数和总列数
    def getRowsClosNum(self):
        rows = self.ws.max_row
        columns = self.ws.max_column
        return rows,columns
    
    #获取某个单元格的值
    def getCellValue(self,row,column):       
        cellvalue = self.ws.cell(row=row,column=column).value
        return cellvalue
    
    #获取某列的所有值
    def getColValues(self,column):
        rows = self.ws.max_row
        columndata=[]
        for i in range(1,rows+1):

            columndata.append(cellvalue)
        return columndata

            self.wb.save(self.file)
