Python 3.x 在python中遍历文件夹时遇到一些问题

我在使用os.walk（）遍历特定文件夹时遇到了一个小问题，即试图计算内存量。似乎可以遍历指定的文件夹（基本上是第一轮）并确定对象是文件还是文件夹

当它进入第二轮（第一轮的第一个子文件夹）时会出现问题。它将不会捕获某些文件，并将返回一个错误

    for folderName, subfolders, filenames in os.walk(original_root_folder):
        space()
        print('The current folder is ' + folderName)

        for subfolder in subfolders:
            print('SUBFOLDER OF ' + folderName + ': ' + subfolder + ', Size is ', (os.path.getsize(subfolder) / 1000), " KB")
            total_size_of_folder = total_size_of_folder + os.path.getsize(subfolder)

        for filename in filenames:
            print('FILE INSIDE ' + folderName + ': '+ filename + ', Size is ', (os.path.getsize(filename) / 1000), " KB")
            total_size_of_folder = total_size_of_folder + os.path.getsize(filename)

    print("Total of folder",(total_size_of_folder/1000)," KB")

这是第一轮的结果，也是期望的结果

    The current folder is C:\Users\Someone\Desktop
    SUBFOLDER OF C:\Users\Someone\Desktop: COMP, Size is  4.096  KB
    SUBFOLDER OF C:\Users\Someone\Desktop: compa, Size is  0.0  KB
    SUBFOLDER OF C:\Users\Someone\Desktop: compa2, Size is  4.096  KB
    SUBFOLDER OF C:\Users\Someone\Desktop: HitFilm Express 2017 Exports, Size is  0.0  KB

这是第二轮

    The current folder is C:\Users\Someone\Desktop\COMP
    SUBFOLDER OF C:\Users\Someone\Desktop\COMP: comp2402a1, Size is  0.0  KB
    FILE INSIDE C:\Users\Someone\Desktop\COMP: comp2402a1.zip, Size is  5.786  KB

这是错误

    Traceback (most recent call last):
      File "C:/Users/Someone/Desktop/Python testing/reg.py", line 129, in <module>
        print('FILE INSIDE ' + folderName + ': '+ filename + ', Size is ', (os.path.getsize(filename) / 1000), " KB")
      File "C:\Users\Someone\AppData\Local\Programs\Python\Python37-32\lib\genericpath.py", line 50, in getsize
        return os.stat(filename).st_size
    FileNotFoundError: [WinError 2] The system cannot find the file specified: 'input.txt'

回溯（最近一次呼叫最后一次）：
文件“C:/Users/Someone/Desktop/Python testing/reg.py”，第129行，在
打印（“+folderName+”内的文件：“+filename+”，大小为“，（os.path.getsize（filename）/1000），“KB”）
文件“C:\Users\Someone\AppData\Local\Programs\Python\Python37-32\lib\genericpath.py”，第50行，在getsize中
返回os.stat（文件名）.st\u大小
FileNotFoundError:[WinError 2]系统找不到指定的文件：“input.txt”

我希望包含文件“input.txt”，但它显然找不到该文件。

os.path.getsize（）在当前工作目录中运行

替换

os.path.getsize（文件名）

使用

os.path.getsize（os.path.join（folderName，filename））
