A simple csv code

[Truman]

import csv
csvFile = open("c:\Python36\files\test.csv", 'w+')
try:
	writer = csv.writer(csvFile)
	writer.writerow(('number', 'number plus 2', 'number times 2'))
	for i in range(10):
		writer.writerow(i, i+2, i*2)
finally:
	csvFile.close()

Error:
Traceback (most recent call last):
  File "C:\Python36\kodovi\csvv.py", line 9, in <module>
    csvFile = open("c:\Python36\files\test.csv", 'w+')
OSError: [Errno 22] Invalid argument: 'c:\\Python36\x0ciles\test.csv'

What did I do wrong? Tried several combinations with several paths but it gave me similar error. I didn't create files directory, expecting that it will be created as per this code.
