I-Python 3.8 ikhupha

Izinto ezintsha ezinomdla kakhulu:

• Inkcazo yesabelo:

  Entsha := umsebenzisi ikuvumela ukuba unike ixabiso kwizinto eziguquguqukayo ngaphakathi kweentetho. Umzekelo:
  ukuba (n := len(a)) > 10:
  print(f"Uluhlu lude kakhulu ({n} iziqalelo, kulindeleke <= 10)")

• Iingxoxo zesikhundla-kuphela:

  Ungakhankanya ngoku ukuba yeyiphi iparameters yomsebenzi enokudluliselwa kwi-syntax yengxoxo enegama kwaye engenakho. Umzekelo:
  def (a, b, /, c, d, *, e, f):
  shicilela(a, b, c, d, e, f)

  f(10, 20, 30, d=40, e=50, f=60) # Kulungile
  f(10, b=20, c=30, d=40, e=50, f=60) # imposiso, `b` ayinakuba yingxabano enegama
  f(10, 20, 30, 40, 50, f=60) # imposiso, `e` mayibe yingxabano enegama

  Olu tshintsho lunika abaphuhlisi indlela yokukhusela abasebenzisi bee-APIs zabo kutshintsho kumagama eengxabano zomsebenzi.

• Inkxaso yeentambo ze-f = kwiinkcazo zokuzibhala kunye nokulungiswa kweempazamo:

  Iswekile eyongeziweyo ukwenza lula ukulungisa/ukugawula imiyalezo.
  n = 42
  shicilela(f'Molo hlabathi {n=}.')
  # iya kuprinta "Molo hlabathi n = 42."

• Kulungiswe igama elingundoqo eliqhubekayo kwibhloko ekugqibeleni (ayizange isebenze ngaphambili).

Okunye:

• Ungayichaza ngokucacileyo indlela eya kwi-bytecode cache endaweni yokungagqibekanga __pycache__.
• Debug kunye nokuKhupha ukwakha sebenzisa i-ABI efanayo.
