Question

嘿，我需要帮助来处理仿真数据

我正在构建一个函数来检查给定路径中命名文件夹的最高4位数字，以及是否包含名为“ shearrate”的文件。这是在路径本身的目录中以及给定路径中每个未命名为4位的文件夹中完成的。

在我添加检查文件是否存在之前，该功能可以正常工作。

如果能帮助您，将不胜感激：）

def file_filter (folder):
    if folder.isdigit() and len(folder) == 4:
        return True

def scan_directory(path, name):
    folderlist = []
    folder_level_1 = 0
    folder_level_2 = 0

    for folder in os.listdir(path):                                     
        if os.path.isdir(os.path.join(path, folder)):                  
            if file_filter(folder) is True:                             
                a_file = Path(os.path.join(path, folder, name))
                if a_file.is_file():
                  if int(folder) > int(folder_level_1):                   
                      folder_level_1 = folder                       
            else:                                                      
                for folder2 in os.listdir(os.path.join(path, folder)):  
                    if file_filter(folder2) is True:                    
                        a_file = Path(os.path.join(path, folder, name))
                        if a_file.is_file():                            
                            if int(folder2) > int(folder_level_2):      
                                folder_level_2 = folder2

                if file_filter(folder_level_2) is True:
                    folderlist.append(os.path.join(path, folder, folder_level_2))

                folder_level_2 = str(0)

    folderlist.append(os.path.join(path, folder_level_1))
    return folderlist

folderlist = scan_directory(path, "shearrate")

我得到的错误：

Traceback (most recent call last):
  File "data_evaluation.py", line 141, in <module>
    search_files("shearrate", path)
  File "data_evaluation.py", line 107, in search_files
    folderlist = scan_directory(path, name)
  File "data_evaluation.py", line 98, in scan_directory
    folderlist.append(os.path.join(path, folder_level_1))

Answer 1

由于错误指出join不能采用int，因此您需要将输入变量的类型改为str：

folderlist.append(os.path.join(path, str(folder_level_1)))

Answer 2

据我所知，您在调用需要int参数的join之前将文件夹转换为string。在错误消息中这样说。我建议您在调用os.path.join之前先打印出该变量的值。两种方法都可以强制转换回字符串str(folder_level_1)。

加入路径检查文件是否存在时出错
