我现在有一个包含文件路径列表的文件。我想循环打开它们进行读写。谁能建议如何做到这一点？到目前为止我所看到的只是阅读这些行并将它们打印出来，我希望我的代码打开这些路径。以下是路径文件的一部分：

E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496340.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496341.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496342.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496343.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496344.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496345.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496346.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496347.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496348.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496349.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496350.txt
E:\Grad\LIS\LIS590 Text mining\Part1\Part1\awards_1994\awd_1994_96\a9496351.txt
...

这是我正在尝试的代码：

def work_on(r'E:\Grad\LIS\LIS590 Text mining\file+test.txt'):  # The last quotation mark gives me that error. I also tried double quotation mark, didn't work either.
    with open(r'E:\Grad\LIS\LIS590 Text mining\file+test.txt', 'r') as data_file:

with open('file_list.txt', 'r') as file_list:    #file_list.txt is the file name I saved all the paths.
    for filename in file_list:
        with open(filename, 'r') as data_file:
            work_on(filename)

一般流程与打印行相同 - 唯一的区别是您将做其他工作而不是使用print()您将做其他工作（在这种情况下打开一个文件并使用它）：

with open('/your/file/list.txt', 'r') as file_list:
    for filename in file_list:
        with open(filename, 'r') as data_file:
            # work with data_file here

然后，如果有意义的话，您可以将第二项工作分解为一个单独的函数：

def work_on(data_file_path):
    with open(data_file_path, 'r') as data_file:
        # work with data_file here

然后将您的工作循环简化为：

with open('/your/file/list.txt', 'r') as file_list:
    for filename in file_list:
        work_on(filename)
