Both pylint and pychecker pick this up. I wrapped the code in a
function (to prevent importing from running in an infinite loop) and ran
both pylint and pychecker:
plyint: W: 5:myfunc: Unused variable 'ego1d'
pychecker: test.py:4: Local variable (ego1d) not used
I make a habit to run pylint or pychecker on my code often. They pick
up a lot of stuff like unused variables, etc.
But you can also do this:
/* initialize variables i'm gonna use */
int vara = 0;
int varb = 0;
while (vara < 10) {
varb = vara + 1;
}
So we can make a similar mistake in C if you type the wrong (declared)
variable name. Moreover, "gcc -Wall" did not report the "unused"
variable so it might be even more difficult to track down the problem.
