python call error module, report file not found

Problem Description

Call readData modules other modules, can not find a file found. If the module directly through readData, there would be no problem. I am very interested in this issue, so now we begin to solve this problem, right?

Solutions

Through the above description of the problem, we can know the path to the file without problems. Just call the procedure, it appears for some reason can not find the path. Let's take a look at the error message:

C:\Users\lenovo\AppData\Local\Programs\Python\Python37\python.exe D:/360MoveData/Users/lenovo/Desktop/startProject/OAS.Cloud.PAAS_Interface/TestCases/UM/Test_01_register.py
Traceback (most recent call last):

    path = readCase.readCasedata("UM", "Test_01").getPath()

    self.archive = _validate_archive(fn)

    archive = ZipFile(filename, 'r')
  File "C:\Users\lenovo\AppData\Local\Programs\Python\Python37\lib\zipfile.py", line 1207, in __init__
    self.fp = io.open(file, filemode)
FileNotFoundError: [Errno 2] No such file or directory: 'caseModel.xlsx'

Process finished with exit code 1

The module is taken in a relative path when running in this file, which will find the directory of the current folder. But when he called, calling its files in another directory, perhaps for this reason it can not successfully call. This is my guess, we are now going to verify it.

solution

1, the absolute path validation

f.wb = load_workbook(filename=r'D:\360MoveData\Users\lenovo\Desktop\startProject\OAS.Cloud.PAAS_Interface\common\caseModel.xlsx', read_only=True, )

Validation results:

description, our guess is correct. I rely on, I was a fucking genius!

2, os generate absolute path

Code migration to other places, we can not continue to change the path, right? Therefore, we adopted os module to generate an absolute path, so to solve this problem.

        dir_path = os.path.dirname(os.path.abspath(__file__))
        self.wb = load_workbook(filename=os.path.join(dir_path,'caseModel.xlsx'), read_only=True, )

The results show:
