[英]PYTHON: Upload text file then split into smaller text files in every n lines
I'm having a problem splitting my file.我在拆分文件时遇到问题。 This is my code for uploading a file.
这是我上传文件的代码。
def upload_file(request):
if request.method == 'POST':
form = UploadFileForm(request.POST, request.FILES)
file = request.FILES['file']
return HttpResponse(str(file) + "is uploaded")
else:
form = UploadFileForm()
return render(request, 'upload.html',{'form':form})
I don't have any idea how to split the file that was uploaded.我不知道如何拆分上传的文件。 Like in every 20 lines, it'll split into smaller text files like this: File(1).txt, File(2).txt.... Thanks in advance!
就像每 20 行一样,它会拆分成更小的文本文件,如下所示:File(1).txt, File(2).txt.... 提前致谢!
def break_file(filepath,lines):
file=None
with open(filepath) as largefile:
for n,text in enumerate(largefile): #goes through each line
if n%lines ==0 :
if file: #check if previous file is already open.
file.close()
file_num = 1+ n/lines # 1 if you want file name to start from1
file_name = 'File({}).txt'.format(file_num)
file= open(file,"w")
file.write(text)
if file:
file.close()
