python - Turning a list or user generated strings into a single string -


i'm getting input users list of strings, ie:

['a','b','c','d']

the strings "hat" short essay. need store list in database string, , pull string out , turn list later. advice on safest / fastest way this? far i've considered:

  • csv
  • json
  • using longish delimiter string (&break;)

my preference, far, msgpack (and xml). has canonical interface protocol.dumps/protocol.loads similar json , support python base types similar json , other packing libs.

  • json readable both human , programs, lot of tools e.g. jsonselect or postgresql.

  • pickle handy complex python types/classes #lazy

  • msgpack performant speed & space wise. can swap json , it's not "bloated". works great utf-8.

  • csv ok lists , tables. it's more compact json , easy parse when it's under control #security. can save some cpu cyles & bandwidth. doesn't support nested lists default.

  • xml portable, verbose, validation frameworks makes easier understand. has loads of tools.

using longish delimiter string

this looks using "rare" character, can break. , if matters, longish thing can make performance burden.

neo4j

since using neo4j it's better go json easier compatibility explorer.

tips: never use list in protocols, it's have smallest possible messages when there bug it's unreadable or clutter code. backward compatibility burden. prefer dict represent objects , list represent real lists or set object. using dictionary allow application/protocol self-document. http 1.x that.
