How big can a Python program be?

[vronskij]

Hi,

A C program can be hundreds of thousands lines of code big.
C++ millions.

How about Python?

Suppose , you are a sole programmer (lonewolf). How many lines can one handle?

Thanks,

What are you actually asking? What technical limitations,
such as maximum line count per module, Python might have?

Or how productive the average programmer can be in terms
of lines of Python code produced per day?

Or something else entirely?

Note that lines of code is a pretty poor measure of productivity,
especially if you just use an average statistic, because it's
hard to judge whether those lines are bug-free or bug-ridden,
and because there is an extremely wide variation in productivity
between different programmers (one oft-published ratio is 30:1).

And more importantly than anything: why do you want to know
such things? This information is critical to providing you
with a useful answer.

$ wc -l my_current_big_ project_that_is _very_far_from_ being_complete/*

I'm sure others can do better than that.

Are you suggesting that a solo programmer wrote a multi million line C++
program? If not then what has this to do with 'How many lines can one handle?'

The application I am currently working on has 75,000 lines across some 600
files. But I suspect that the line count is higher when you include the various
libraries. So I am handling 75,000 lines in some sense, is this what you mean?
Or are you talking about the number of lines per file (average 125) or perhaps
lines per method?

Well, heres my quarter-million line Python 'Program' executing
pad@Williams-McCarthy:/tmp$ python -c 'print "x=0"
for i in xrange(2**18):p rint "x+=",`i`
print "print x"' > silly.py
pad@Williams-McCarthy:/tmp$ wc -l silly.py
262146 silly.py
pad@Williams-McCarthy:/tmp$ nice python silly.py
34359607296
It did start to swap but didn't take too long to finish on my 256Meg
Debian Linux, Athlon 1470MHz machine

:-) Pad.

Heh,

No way. This was just another question. One programmer told me that
he
can roughly handle max 10 000 lines in C language. I was curious
about Python. I always hear that Python can be used on larger projects
than e.j. PERL because it is Object Oriented and cleanly designed.
What is a larger project? Mumbers revail more.

This is probably team work. It's helpful for me to know figures. When
you start a project it is useful to know the limitations of a
language. Visual Basic is reported to fail on larger projects.

Of course 10,000 lines of Python will usually encompass much more
functionality than 10,000 lines of C, because Python is a higher-level
language, so you need to be careful you're comparing like with like. I
have never tried to write 10,000 lines of Perl, and would never do so
unless (a) I was being paid an obscenely large amount of money for it
and (b) I had a cast-iron guarantee that I would never have to look at
it ever again.

But a simple line-count is less revealing than actual project scope
IMHO. What does this 10,000-line C program actually do? How much effort
would it be to do that in Python? In a lot of cases, the answer will be
that it is much less effort in Python, and fringe benefits of that are
likely to include shorter and more legible code than you had in C. You
might be able to do it in APL in far fewer lines, but as to effort and
legibility... YMMV!

The problem is that some languages are much more verbose than others, thus a 100
line python program might require 2,000 lines of C or 700 lines of C++ (I'm just
making up numbers here). What then counts is the programmers ability to read the
source and summarise (oh, that's just creating back orders if we are out of
stock). The more verbose the language the more likely they will have a problem
comprehending the intent of the code. Imagine trying to comprehend a C program
against its assembly equivalent. C is easier to read than assembly and Python is
easier to read than C.

I suppose languages have a conciseness metric but I would not know how to
measure it. On the other hand APL is very short by just as hard to read.

Perl is used on some very large projects! The 75,000 lines I mentioned was Perl
and I would not count that as a large project.

files.

This is probably team work. It's helpful for me to know figures. When
you start a project it is useful to know the limitations of a
language. Visual Basic is reported to fail on larger projects.

It was created by a team for sure but when an upgrade or fix is required then
only one programmer is looking at the whole of the code so they have to handle
the entire codebase. A well designed codebase / object hierarchy helps here.

As to Basic, the non VB sort, I have worked on financial systems that were
written in Vax Basic that were many 1,000s of lines long. The language is not
the problem. With VB the problem is that you never really got to work with the
code, the IDE was always in the way and the IDE only existed at the program
level and not the project.
