Inkinga enkulu ngokusebenzisa uhlu lwamanga lwangempela ukumela okumnyama nokumhlophe ukuthi kungaba nzima ukusho ukuthi yiziphi izici eziyiqiniso nokuthi yiziphi ezingamanga.
import numpy as np
def rgb2gray(rgb):
return np.dot(rgb[...,:3], [0.299, 0.587, 0.114])
Le khodi ingenisa ngaphandle umtapo wezincwadi futhi ichaza umsebenzi wokuguqula isithombe se-RGB sibe greyscale. Umsebenzi uthatha isithombe se-RGB njengokufakiwe bese ubuyisela isithombe esimpunga.
I-Arrays
Amalungu afanayo iqoqo lezinto ezigcinwe ezindaweni zememori ezihlangene. Ama-arrays angadalwa kusetshenziswa umsebenzi we-list(), futhi angafinyelelwa kusetshenziswa inombolo yenkomba (eqala ku-0) noma igama lamalungu afanayo.
Isibonelo se-array kuPython singabukeka kanje:
uhlu(1, 2, 3)
AmaBoolean
Ku-Python, i-boolean iwuhlobo lwedatha olungathatha kuphela inani elilodwa kwamabili okungenzeka: Iqiniso noma Amanga. Ngamanye amazwi, i-boolean ingacatshangwa njengempendulo ethi "yebo" noma "cha".
Amabhunu asetshenziswa ezimeni eziningi kuPython, okuhlanganisa lapho kuhlolwa izimo ezitatimendeni ezinemibandela nalapho kwenziwa izinqumo mayelana nokuthi iyiphi ikhodi okufanele isebenze.
