How do I write to the file I selected using filedialog.asksaveasfile?

I am trying to write to a file that I just created using the filedialog.asksaveasfile. I set the mode to 'w'. Do I have to open the file again or something?

f = filedialog.asksaveasfile(mode='w', defaultextension=".csv")

keyList = []

for n in aDict.keys():
    keyList.append(n)

keyList = sorted(keyList, key=operator.itemgetter(0,1))
csvWriter = csv.writer(f)

for key in keyList:
    sal1 = aDict[(key[0],key[1])][0]
    sal2 = aDict[(key[0],key[1])][1]
    csvWriter.writerow(key[0], key[1], sal1, sal2)

f.close()

You can simply use the write function of the reference (of type _io.TextIOWrapper) returned by the asksaveasfile function.

For example

from tkinter import filedialog, Tk

root = Tk().withdraw()

file = filedialog.asksaveasfile(mode='w', defaultextension=".csv")

if file:
    file.write("Hello World")
    file.close()

Note that the object returned by the asksaveasfile function is of the same type or class of the object returned by the built-in open function. Note also that the same function returns None, if Cancel is pressed when the dialog pops up.
