python - 发现打开文件错误 : TypeError: coercing to Unicode: need string or buffer, 列表

Question

我有以下代码:基本上我正在做的就是寻找一个 .csv 文件，该文件可能位于两个位置之一(或更多取决于) 我在文本文件 (LocationsFile.txt) 中有两个特定位置。

除此之外，我只想获取学生的特定字段:这是SSID 字段

我有以下代码，但它似乎给我的错误如下:

    Tape Name130322
['\\\\....HIDDEN FOR Confidenciality .....StudentDB1_av.csv']
Success:
Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 1410, in __call__
    return self.func(*args)
  File "C:\Users\Administrator\Desktop\John\Spreadsheet\Gui.py", line 291, in run
    findStudentData('130322','StudentDB1')
  File "C:\Users\Administrator\Desktop\John\Spreadsheet\Gui.py", line 62, in findStudentData
    with open(items) as f:
TypeError: coercing to Unicode: need string or buffer, list found

正在执行的代码如下: - 请在回复时考虑周到，因为我是一个“新手”Python程序员!

def findStudentData(student_name,course):
student_name= student_name.lower()
configfiles = []

print "student_name" + student_name
for path in MMinfo_paths:
    configfiles.append(glob.glob(path+"/" + course+"*"))

for items in configfiles:
    print items
    print "Success:"
    heading = True

    with open(items) as f:
        content = f.read()

        if heading == True
            ssidCol = content.index('ssid')
            flagsCol = content.index('flags')
            nameCol = content.index('name')
            heading = False
            continue



        for item in rowData:
            if rowData.index(item) == nameCol:
                print rowData
            else:
                continue

非常感谢:-)

Answer 1

现在，您的配置文件如下所示:

[[file1, file2], [file3, file4]]

您可以执行以下操作:

for items in configfiles:
    for filename in items:
        with open(items) as f: ...

或者，您可以将 configfiles.append 替换为 configfiles.extend。 Append 将 glob 返回的列表添加为配置文件列表的元素，而extend 将 glob 返回的列表的每个元素添加到配置文件列表。那么，配置文件将是:

[file1, file2, file3, file4]

你可以这样写:

for items in configfiles:
    with open(items) as f: ...
