xlrd是Python常用于读取excel文件的库:

1.例如读取下面这张表

2.读取文件的方式：
# 创建一个excel对象：
excel = xlrd.open_workbook(filename)

# 返回excel一个名为“Sheet1“的sheet页对象 
data = excel.sheet_by_name("Sheet1")

# 读取行数 
rows = data.nrows

# 读取第row行的值 
years = data.row_values(row) 

# 读取列数 
cols = data.col  

# 读取第col列 
provinces = data.col_values(col)

=============================================================================================================
3.具体代码

# 创建一个DataInit类，文件名：GetFile.py

#! -*- coding:utf-8 -*-

import os
import xlrd


class DataInit(object):

    def __init__(self, row=0, col=0):
        self.name = "DATA.xlsx"
        self.path = os.getcwd()
        self.provinces = list()
        self.years = list()
        self.data = None
        self.row = row
        self.col = col

    def getfile(self, row, col):

        filename = self.path+"\\"+self.name
        # 创建一个excel的对象
        excel = xlrd.open_workbook(filename)

        # 返回excel一个名为“Sheet1“的sheet页对象
        self.data = excel.sheet_by_name("Sheet1")
        # 读取行数
        rows = self.data.nrows

        # 读取表头即第0行的值
        self.years = self.data.row_values(row)
        # print("统计年限：", self.years)

        # 读取列数
        cols = self.data.col

        # 读取列
        self.provinces = self.data.col_values(col)
        # print("统计全国各省和直辖市：", self.provinces)
        return self.data

    @staticmethod
    def get_row(data, row):
        row_value = data.row_values(row)
        return row_value

    @staticmethod
    def get_col(data, col):
        row_value = data.col_values(col)
        return row_value

    def data_init(self, data, row, col):
        city = self.get_row(data, col)
        years = self.get_col(data, row)
        return city, years


============================================================================================================

# 实现文件读取，文件名：readfile.py
#! -*- coding:utf-8 -*—

from lib.GetFile import DataInit

def draw():
    data_init = DataInit()
    data = data_init.getfile(1,1)
    city, year = data_init.data_init(data, 1, 1)
    print(city)
    print(year )

if __name__ == "__main__":
    draw()
