Question

I worked out a code that make sense to me but not python since I’m new to python.

Check my code here:

checksum_algos = ['md5','sha1']

for filename in ["%smanifest-%s.txt" % (prefix for prefix in ['', 'tag'],  a for a in checksum_algos)]:
  f = os.path.join(self.path, filename)
  if isfile(f):
     yield f

My intention is to search filename in a list like :

['manifest-md5.txt','tagmanifest-md5.txt','manifest-sha1.txt','tagmanifest-sha1.txt']

but I got syntax problem to implement it.

Thanks for any help.

Answer 1

You’re overthinking it.

for filename in ("%smanifest-%s.txt" % (prefix, a)
    for prefix in ['', 'tag'] for a in checksum_algos):
