Howdy, I had the impression that pychecker caught and reported such
dynamic syntactical errors.
#!/usr/bin/env python
def add(i):
i += 10
status = 3
if 1 == 1:
statuss = 15
add(status)
=============== ========
exalted sysfault$ pychecker foo.py
Processing foo...
Warnings...
None
=============== ========
Hence the mispelling of status (statuss), which was done purposely to test
if pychecker will acknowledge and report the error. Do i need to enable
some type of pychecker option in order for it to pick up the error? I know
that it is syntactically correct in python, however it's likely that
'status' is meant. Am i wishing that pychecker will replace a statically
typed language mechanism?

I think you're asking a lot from pychecker.
kop = 1
koi = 2
if True:
koo = 3
What would you like pychecker to report?

That's a functional error, not a syntactical one. Analyzing the
spelling of variables for similarity would lead to a lot of incorrect
warnings since pychecker has no way to tell this apart from intentional
similar spellings such as:
values = [1, 2, 3]
value = values[0]
However, when the misspelling is made inside a local scope, rather than
at the module level a warning is reported "test.py:8: Local variable
(statuss) not used":
def add(i):
i += 10
def test():
status = 3
if 1 == 1:
statuss = 15
add(status)
This is why tools like pychecker (or pyflakes, pylint, or even a static
code compiler) aren't a substitute for unit tests. They can definitely
help catch common mistakes, but they can't ensure your code does what
you intended.

I thing the OP was hoping for a "not used" error, but it can only reasonably
do that within a function, which it does do:
pyc.py:2: Local variable (kop) not used
pyc.py:3: Local variable (koi) not used
pyc.py:6: Local variable (koo) not used
At the module level it doesn't know that the suspect object isn't accessed
from another module.

A new version of PyChecker is (finally) available for your hacking pleasure.
It's been quite a while since the last release--11 months.
I wish there was more progress, but such is life.
Many bug fixes and some new warnings were added.
I hope to get future releases out faster. I have several patches
queued up and ideas for more warnings. As always, I'd like

Is there a practical way to use Pychecker in Windows? It doesn't work
under IDLE. (In fact, it seems to end up breaking everything, and
every subsequent statement and expression I execute gets ignored.)
Running it from the Python interpreter in DOS means everything scrolls
off the screen. Ideally I'd like to redirect it to a file, or be able
to use it in IDLE.

Hello,
I take PyChecker partly as an recommender of good coding practice, but I
cannot make sense of some of the messages. For example:
runner.py:878: Function (main) has too many lines (201)
What does this mean? Cannot functions be large? Or is it simply an advice that
functions should be small and simple?

Hi,
I would like to develop a tool that goes one step further than pychecker
to ensure python program validity. The idea would be to get close to
what people get on ocaml: a static verification of all types of the
program, without any kind of variable declaration. This would definitely
brings a lot of power to python.
The idea is to analyse the whole program, identify constraints on
function arguments and check that these constraints...

Version 0.8.15 of PyChecker is available. It's been over a year since

you won't have any more bugs. :-)
