Why remember when os.pathsep will do it for you.
However, for windows you need a bit more:
def which(command):
win32 = sys.platform == 'win32'
if win32:
# Case-insesitive file names and file exts for commands
try:
knownexts = [''] + os.getenv('PATHEXT').split(os.pathsep)
except AttributeError:
knownexts = ['']
else:
knownexts = [ext.lower() for ext in knownexts]
test = command.lower()
tests = set(test + ext for ext in knownexts)
else:
tests = set([command])
for dirname in os.getenv('PATH').split(os.pathsep):
try:
files = os.listdir(dirname)
except IOError:
continue
else:
for name in files:
if name in tests or win32 and name.lower() in tests:
yield dirname, name
