Here's a few ways,
map(os.remove, glob.glob("*.m3u"))
[os.remove(x) for x in glob.glob("*.m3u")]
[os.remove(x) for x in os.listdir(src) if
os.path.isfile(os.path.join(src, x))
and len(x.split('.')) > 1
and x.split('.')[-1].lower() == 'm3u']
def myfilter(x):
return os.path.isfile(os.path.join(src, x)) and len(x.split('.')) >
1 and x.split('.')[-1].lower() == 'm3u'
map(os.remove, filter(myfilter, os.listdir(src)))
