FileNotFoundError when creating a file using a variable in Python 3.5.1

I'm trying to create a file using a variable in Python, but it just won't have it. Here is the code that creates the filename:

a, b = time.strftime("%d/%m/%Y"), time.strftime("%H-%M-%S")
c = ("SCORE"+"-"+"("+a+")"+"-"+"("+b+")")
c = str(c+".txt")

This prints: SCORE-(28/12/2015)-(21-05-09).txt

That is the filename and file extension (.txt). So, I try to create a file using this, using this snippet of code:

file3 = open(c,"w+")
file3.write(file2a)
file3.close()

(file2a is the contents of a text file called SCORE.txt, this works properly).

When I execute this code, it gives me an error:

Traceback (most recent call last): File "E:\Program Files\Python guff\DocMarker\data\FinalScore.py", line 57, in file3 = open(c,"w+") FileNotFoundError: [Errno 2] No such file or directory: 'SCORE-(28/12/2015)-(21-05-09).txt'

This is baffling me, as when I changed the "c" bit to "test", it worked. Like this:

file3 = open("test", "w+")

This successfully created a file called "test" that had the contents of SCORE.txt inside of it. I'm baffled as to why it won't work with my "c" variable.

Because your filename has slashes in it, python is looking for a directory in 

- SCORE-(28
  |
  - 12
    |
    - 2015)-(21-05-09).txt

try refactoring your initial code like this:

a, b = time.strftime("%d-%m-%Y"), time.strftime("%H-%M-%S")
c = ("SCORE"+"-"+"("+a+")"+"-"+"("+b+")")
c = str(c+".txt")

or, in a more compact and more readable way:

c = time.strftime("SCORE-(%d-%m-%Y)-(%H-%M-%S).txt")
