python excel和yaml文件的读取封装

excel

1. import os
2. import xlrd
3.  
4. PATH = lambda p: os.path.abspath(
5. os.path.join(os.path.dirname(__file__), p)
6. )
7.  
8. class ExcelData:
9. def __init__(self, file, sheet="sheet1", title=True):
10. # 判断文件存在不存在
11. if os.path.isfile(PATH(file)):
12. self.file = PATH(file)
13. self.sheet = sheet
14. self.title = title
15. self.data = list()
16. self.workbook = xlrd.open_workbook(self.file)
17. else:
18. raise FileNotFoundError("文件不存在")
19.  
20. @property
21. def get_data(self):
22. """获取表格数据"""
23. if not self.data:
24. # 判断表单名称
25. if type(self.sheet) not in [int, str]:
26. raise Exception("表单名称类型错误")
27. else:
28. if type(self.sheet) == int:
29. book = self.workbook.sheet_by_index(self.sheet)
30. else:
31. book = self.workbook.sheet_by_name(self.sheet)
32. # 判断表格是否有表头，有则输出列表嵌套字典形式数据，否则输入列表嵌套列表形式数据
33. if self.title:
34. title = book.row_values(0)
35. for i in range(1, book.nrows):
36. self.data.append(dict(zip(title, book.row_values(i)))) # 可参考字典章节
37. else:
38. for i in range(book.nrows):
39. self.data.append(book.row_values(i))
40. return self.data
41.  
42. @property
43. def get_sheets(self):
44. """获取所有表单，这个在后续会用到"""
45. book = self.workbook.sheets()
46. return book

调用操作

1. infos = ExcelData("htmls/测试用例.xlsx", "登入页面", True).get_data
2. print(infos)
3.  
4. sheets = ExcelData("htmls/测试用例.xlsx").get_sheets
5. print(sheets)

yaml

1. import os
2. import yaml
3. from yamlinclude import YamlIncludeConstructor
4.  
5. YamlIncludeConstructor.add_to_loader_class(loader_class=yaml.FullLoader) # 用于yaml文件嵌套
6.  
7. PATH = lambda p: os.path.abspath(os.path.join(
8. os.path.dirname(__file__), p
9. ))
10.  
11. class YamlData:
12. def __init__(self, file):
13. if os.path.isfile(PATH(file)):
14. self.file = PATH(file)
15. else:
16. raise FileNotFoundError("文件不存在")
17.  
18. @property # 设置属性，调用data方法时可通过调用属性，不需要带括号
19. def data(self):
20. with open(file=self.file, mode="rb") as f:
21. infos = yaml.load(f, Loader=yaml.FullLoader)
22. # infos = yaml.load(f)
23. return infos

调用操作

1. infos = YamlData("htmls/loginsucess.yaml").data
2. print(infos)
3. "D:\Program Files\Python\Python37-32\python.exe" D:/demo/yamldata.py
4. {'id': 'login_001', 'module': '登入页面', 'title': '登入时账号为空', 'message': '已打开链接', 'testcase': [{'element_info': 'css->[placeholder="请输入账号"]', 'operate_type': 'send_keys', 'keys': 'SSSS', 'info': '点击账号输入框，输入账号'}, {'element_info': 'css->[placeholder="请输入密码"]', 'operate_type': 'send_keys', 'keys': 'XXX', 'info': '点击密码输入框，输入密码'}, {'element_info': 'div->"登 录"', 'operate_type': 'click', 'info': '点击登入菜单'}, {'operate_type': 'is_sleep', 'keys': 3, 'info': '等待进入'}], 'check': None}
5.  
6. Process finished with exit code 0
