It helps to include the full traceback. If we don't know the code that
caused the error, it's pretty hard to say what went wrong, especially
with an exception as broad as SyntaxError. It

The maximum depth of the Python interpreter stack is limited to 1000 calls
by default. You can get it by import sys; sys.getrecursionlimit() and set a
new value to sys.setrecursionlimit(new_value)

Since he's computing the Fibonacci number of n, and n is 900, he needs

Hi all,
Apologies I'm sure this has been asked many times, but I'm trying to
figure out the most efficient way to do a complex sort on very large
files.
I've read the recipe at [1] and understand that the way to sort a
large file is to break it into chunks, sort each chunk and write
sorted chunks
Thanks Thomas, it is what i'm looking for.

A code snippet would work wonders in making sure you've communicated what
you really need, or at least what you have now.
But if you read the data into one big string, that'll be much more efficient
than if you read it as a list of integers or even as a list of lines.

Python 2.x, or Python 3.x?
What are the types of your sort keys?
If you're on 3.x and the key you need reversed is numeric, you can negate
the key.
If you're on 2.x, you can use an object with a __cmp__ method to compare
objects however you require.
You probably should timsort the chunks (which

It's the path that was used to specify the script by whatever

Actually, I used .readline() to parse file line by line, because I need
