[BangPypers] collections

All the best. We will be glad to help you out, if you provide information like your programming background in case any ? could you explain what you mean? is there any fresher job openings related to python yes - many Don't target to learn python for particular job. Once you have basic foundation on python, you can pick things easily but you need to spend considerable amount of time. ?how much knowledge they can expect as a fresher in python ?

Hey Shashidhar,
Others may answer your question, I am not going to do that right away.
I'll just offer a few suggestions to clean up your code. If you do that, I
promise to answer your questions:
a. Use os.path.join() to join path components
b. You don't /have/ to read all the lines of the file into a list before
processing it. The pythonic way would be:
with open(filename) as input_file:
for line in input_file.readline():
...do stuff ...
c. You don't need to iterate over lists using numeric indexes. Even if you
/need/ numeric index, use enumerate. So, instead of :
for index in range(len(somelist)):
...do something with somelist[index] ...
OR
...do something with index ...
use something like:
for element in somelist:
...do something with element...
OR
for index, element in enumerate(somelist):
...do something with index or element
d. Don't chain string operations to just match a substring, use regular
expressions. If you /have/ to chain string operations (for instance, to
extract rather than match), chain them only once. So, instead of :
if
all_lines_in_file[line].split(**'-')[1].split(')')[0].split(**')[1].strip()
== true:
...
...
print ZMP value %s % all_lines_in_file[line].split(**
'-')[1].split(')')[0].split(**')[1].strip()
...and more such monstrosities, do either:
stuff_that_interests_me = line.split('-')[1].split(')')**
[0](')[1].strip()
if stuff_that_interests_me == 'true':
or just:
matched = re.search(-\((.*)\), line) # or some such, depending on the
format
if matched:
stuff_that_interests_me = matched.group()
e. If you need one of three options as values of a dict (which I assume
will serve as a config dict), default the config keys to something. So, do:
config = {'MyFirstKey' : 'ASK',
'MyNextKey' : 'ASK',
...
}
for line in all_lines:
...extract stuff_that_interests_me from line...
if 'MyFirstKey' in line:
if stuff_that_interests_me == 'true':
config['MyFirstKey'] = 'ON'
elif stuff_that_interests_me == 'false':
config['MyFirstKey'] = 'OFF'
...
HTH,
cheers,
- steve
Kudos, Steve. This is definitely the best answer which I have seen in this
discussion group, all these years.
I think you have set an example on how an experienced hand should direct a
not so-experienced one.
Many Many Thanks

So it's mostly vestigial in the code. - d ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
