我是python编程的新手.我有一个counter.txt文件,我从中读取计数器值.使用此计数器值,我必须创建新文件到其他文件夹,如'/home/pi/data/temp/file%s.txt'%line.例如:file1.txt,file2.txt等等.

我为此写了一些代码,由于某种原因,我遇到了以下错误:

IOError: [Errno 22] Invalid argument: '/home/pi/data/temp/file1\n.txt'

我的python代码如下:

while True:

    counter_file = open("counter.txt", 'r+')
    line = counter_file.readline()
    print(line)
    counter_file.close()
    file_read = open(r'/home/pi/data/temp/file%s.txt'%line, 'w')
    #data_line = line_read.decode("utf-8")
    #file_read.write("%s"%data_line)
    file_read.close()
    counter_file = open("counter.txt", 'w')
    line = int(line) + 1
    counter_file.write("%s"%line)
    counter_file.truncate()
    counter_file.close()

当我执行这个,我得到这个追溯:

 File "compute1.py", line 24, in <module>
    file_read = open(r'/home/pi/data/temp/file%s.txt'%line, 'w')
IOError: [Errno 22] Invalid argument: '/home/pi/data/temp/file1\n.txt'

请帮助我这方面.谢谢!
