将目录的所有文件复制到python中的一个文本文件

Question

My intention is to copy the text of all my c# (and later aspx) files to one final text file, but it doesn't work.

For some reason, the "yo.txt" file is not created.

I know that the iteration over the files works, but I can't write the data into the .txt file.

The variable 'data' eventually does contain all text from the files . . .

*******Could it be connected to the fact that there are some non-ascii characters in the text of the c# files?

Here is my code:

import os
import sys

src_path = sys.argv[1]
os.chdir(src_path)

data = ""
for file in os.listdir('.'):
    if os.path.isfile(file):
        if file.split('.')[-1]=="cs" and (len(file.split('.'))==2 or len(file.split('.'))==3):
            print "Copying", file
            with open(file, "r") as f:
                data += f.read()


print data

with open("yo.txt", "w") as f:
    f.write(data)   

If someone has an idea, it will be great :)

Thanks

Answer 1

You have to ensure the directory the file is created has sufficient write permissions, if not run

  chmod -R 777 .

to make the directory writable.

Answer 2

import os for r, d, f in os.walk(inputdir): for file in f: filelist.append(f"{r}\\{file}") with open(outputfile, 'w') as outfile: for f in filelist: with open(f) as infile: for line in infile: outfile.write(line) outfile.write('\n \n')
