Ngoko sinokusebenzisa le datha ngenjongo nayiphi na ixesha esiyidingayo. Nangona kunjalo, kwiimeko ezininzi, ulwazi olufunekayo lufakwe ngaphakathi kwiblogi okanye kwindawo. Nangona ezinye izayithi zenza imizamo yokubonisa idatha kwifom ehleliweyo, ehlelekile necocekileyo, enye ihluleka ukwenza loo nto.

Ukukhwela, ukucubungula, ukucoca kunye nokucoca kwedatha kuyimfuneko kwi-intanethi yoshishino.

Ngokukhawuleza okanye kamva, kuya kufuneka ubhekisele kummandla wePython ukufikelela kwiinkqubo ezahlukeneyo, izikhokelo kunye nesofthiwe yokubamba idatha yakho. Nazi ezinye iiprogram zePython ezidumile kunye ezivelele zokutshiza kunye nokukhwabanisa iziza nokukhupha idatha oyifunayo kwishishini lakho.

Ezinye iilwimi

Ukuba awukhululekile kwiiprogram ezichazwe ngasentla, ungazama uCola, iDemiurge, uMncedisi, uLassie, uRoboBrowser kunye nezinye izixhobo ezifanayo. Ngeke kuphosakele ukutsho ukuba uluhlu lugqityiwe kwaye lukho uninzi lwezikhetho kulabo abangathandi iikhowudi ze-PHP kunye ne-HTML.
