The last day is tomorrow, so I'll actually try and write something
real then... I just wanted to say that this has been a pretty good
class. Really good, compared to others I've taken (in college and so
forth)...
Anyway, just thought I'd share this:
The difference between me (learning a new language) and the guy
teaching (who knows it inside and out)
My code:
import os
startDir = '/home/student/testdirectory' #raw_input("Enter starting location: ")
searchList=['html','py','jpg']
filenames=[]
report={}
try:
fhtml=open('HTMLFiles','w')
fpy=open('PYFiles','w')
fjpg=open('JPGFiles','w')
except:
assert 0, 'Unable to open file'
for root, dirs, files in os.walk(startDir):
filenames += [os.path.normcase(os.path.join(root,f))
for f in files if f[f.rfind('.')+1:] in searchList]
for file in filenames:
ext=file.split('.')[1]
if report.has_key(ext):
report[ext].extend([file])
else:
report.update({ext:[file]})
for k,v in report.iteritems():
if k == 'html':
for item in v:
fhtml.write("%s\n" % item)
if k == 'py':
for item in v:
fpy.write("%s\n" % item)
if k == 'jpg':
for item in v:
fjpg.write("%s\n" % item)
His code:
import os
def FindFiles(base_dir="/", exten=[]):
results={}
# Initialize results dictionary with blank arrays
for l in exten:
results[l]=[]
for root, dirs, files in os.walk(base_dir):
for e in exten:
results[e] += [os.path.join(root,fn) for fn in files if
fn.endswith(e)]
return results
files=FindFiles('C:/Python26',['exe','html'])
for (exten, list) in files.iteritems():
try:
f=open('extensions-%s.txt' % exten,'w')
f.write('\n'.join(list))
except:
assert 0, 'Unable to create output file extensions-%s.txt.' % exten
Different thought processes, plus experience makes a difference too...
That and while I have an educational background in programming, the
only programming I've been able to do in my professional (read daily)
life is BASH... I think it shows.
Cheers,
Jeff
