• python转换excel成py文件


    python转换excel成py文件


      文件结构如下:

        originExcelFolder放用来转换的excel文件。

        targetPyFolder用来存放最后生产的py文件。

        setting.py用来配置excel表到py的对应关系。

        excel2py.py是主要的处理文件。

        


      Excel文件,A注意表名字,B注意sheet名字。

        


     代码如下:

      setting.py

    #!/usr/bin/env python
    #-*- coding: utf-8 -*-
    
    # setting.py # 定义生成py表的格式
    
    Dict ={
        "student":{
            "id": {'type':int, 'default': 0},
            "name":{'type':str, 'default': None},
            "age":{'type':int, 'default': 0},
            "sex":{'type':str, 'default': 'F'},
        }
    }
    
     
    

      excel2.py

      

    #!/usr/bin/env python
    #-*- coding: utf-8 -*-
    
    # transfer excel to py
    # 处理excel表格生成对应的py文件

    注意:这里只处理了一个表的一个sheet,如果想要处理多个表多个sheet可稍作修改即可。
