python应用_读取Excel数据【二】_二次封装之函数式封装

目的：想要把对Excel文件读取做成一个通用的函数式封装，便于后续简单调用，隔离复杂性。

未二次封装前原代码：

#coding=gbk

import os
import xlrd

current_path=os.path.dirname(__file__)
excel_path=os.path.join(current_path,‘../testcase.xlsx‘)

workbook=xlrd.open_workbook(excel_path)
sheet=workbook.sheet_by_index(0)

all_case_info = []
for i in range(1,sheet.nrows):
    case_info = []
    for j in range(0,sheet.ncols):
        case_info.append(sheet.cell_value(i,j))
    all_case_info.append(case_info)

print(all_case_info)

更改后：

原文件：

#coding=gbk
import os
import xlrd

current_path=os.path.dirname(__file__)
excel_path=os.path.join(current_path,‘../testcase.xlsx‘)

def read_excel_date_convert_case_info(excel_path):
    workbook = xlrd.open_workbook(excel_path)
    sheet = workbook.sheet_by_index(0)
    all_case_info = []
    for i in range(1,sheet.nrows):
        case_info = []
        for j in range(0,sheet.ncols):
            case_info.append(sheet.cell_value(i,j))
        all_case_info.append(case_info)
    return all_case_info    #一定要有返回

#顶层代码调试
if __name__ == ‘__main__‘:
    current_path = os.path.dirname(__file__)
    excel_path = os.path.join(current_path, ‘../testcase.xlsx‘)
    cases=read_excel_date_convert_case_info(excel_path)
    print(cases)

调用：

#coding=gbk
import os
from  test0418.demo02 import read_excel_date_convert_case_info   #引入对应的函数

current_path = os.path.dirname(__file__)
excel_path = os.path.join(current_path, ‘../testcase.xlsx‘)
cases = read_excel_date_convert_case_info(excel_path)  #别人调用时候只需要import该函数，然后直接
print(cases)  #检测输出结果
