Listing all imported and exported symbols

The imports can be listed as follows:

for entry in pe.DIRECTORY_ENTRY_IMPORT:
  print entry.dll
  for imp in entry.imports:
    print '\t', hex(imp.address), imp.name

Likewise, we can't list the exports:

for exp in pe.DIRECTORY_ENTRY_EXPORT.symbols:
  print hex(pe.OPTIONAL_HEADER.ImageBase + exp.address), exp.name, exp.ordinal
