How to read and write a file using python?

I want to write the text (which I get from AJAX) to a file, and then re开发者_开发百科ad it.

If you can use this in Django view... try somethink like this:

def some_view(request):
    text = request.POST.get("text", None)
    if text is not None:
        f = open( 'some_file.txt', 'w+')
        f.write(text)
        f.close()
    return HttpResponse()

The following code for read the content from a file

handle=open('file','r+')
var=handle.read()
print var

If you want to read a single line use the readline(). If you want to read the whole lines in the file use the readlines() also

The following code for writing the content to the file

handle1=open('file.txt','r+')
handle1.write("I AM NEW FILE")
handle1.close()

---

f = open( 'filename.txt', 'w+' )
f.write( 'text' )
f.close()

f = open( 'filename.txt', 'r' )
for line in f:
    print( line )
f.close()

You can try this out

with open("file.txt", "r+") as file:

     for i in file:
         file.write(i + "\n")
file.close
