在下面的代码中，我试图打开一系列文本文件并将它们的内容复制到一个文件中。我在“os.write（out_file，line）”上遇到错误，它要求我输入一个整数。我还没有定义什么是“线”，那是问题吗？我是否需要以某种方式指定“行”是 in_file 中的文本字符串？此外，我通过 for 循环的每次迭代打开 out_file。那不好吗？我应该在开始时打开一次吗？谢谢！

import os
import os.path
import shutil

# This is supposed to read through all the text files in a folder and
# copy the text inside to a master file.

#   This defines the master file and gets the source directory
#   for reading/writing the files in that directory to the master file.

src_dir = r'D:\Term Search'
out_file = r'D:\master.txt'
files = [(path, f) for path,_,file_list in os.walk(src_dir) for f in file_list]

# This for-loop should open each of the files in the source directory, write
# their content to the master file, and finally close the in_file.

for path, f_name in files:
    open(out_file, 'a+')
    in_file = open('%s/%s' % (path, f_name), 'r')
    for line in in_file:
        os.write(out_file, line)
    close(file_name)
    close(out_file)

print 'Finished'

你这样做是错的：

你做了：

open(out_file, 'a+')

但这不会将引用保存为变量，因此您无法访问刚刚创建的文件对象。你需要做什么：

out_file_handle = open(out_file, 'a+')
...
out_file_handle.write(line)
...
out_file_handle.close()

或者，更蟒蛇：

out_filename = r"D:\master.txt"
...
with open(out_filename, 'a+') as outfile:
    for filepath in files:
        with open(os.path.join(*filepath)) as infile:
            outfile.write(infile.read())

print "finished"
