Python NumPy: Aiki tare da Arrays da Asarray_chkfinite Aiki

Arrays shine ainihin ra'ayi a cikin shirye-shirye da sarrafa bayanai. A cikin Python, ana amfani da ɗakin karatu na NumPy sau da yawa don aiki tare da tsararru, saboda yana kawo kayan aiki da yawa waɗanda ke sauƙaƙe ayyukan ƙididdiga da sauran magudi. A cikin wannan labarin, za mu mai da hankali kan takamaiman aikin NumPy: aikin asarray_chkfinite. Wannan aikin yana taimakawa don jujjuya lissafin da aka bayar zuwa tsararrun NumPy yayin duba idan duk abubuwa sun ƙare. Bayan gabatarwa ga wannan aikin, za mu nutse cikin bayanin mataki-mataki na lambar kuma mu bincika ayyukan NumPy da ɗakunan karatu masu alaƙa.

Gabatarwa zuwa Aikin NumPy asarray_chkfinite

The asarray_chkfinite aiki yana daga cikin Lambobi ɗakin karatu, wanda aka ƙera don yin aiki tare da tsararru da matrices yadda ya kamata. Makasudin wannan aikin shine canza lissafin da aka bayar zuwa tsararrun NumPy, yayin da kuma tabbatar da cewa duk abubuwan da ke cikin tsararrun suna da iyaka. Idan akwai wasu abubuwa marasa iyaka, kamar NaN ko rashin iyaka, za a ta da kuskure. Wannan rajistan yana da amfani a yanayi da yawa inda bayanai dole ne su kasance masu tsabta kuma abin dogaro, kamar yadda ɓata ko ƙimar da ba daidai ba na iya haifar da ƙididdige ƙididdiga da ƙare ba daidai ba.

Domin amfani da aikin asarray_chkfinite, dole ne ka fara shigo da ɗakin karatu na NumPy ta hanyar gudanar da lambar mai zuwa:

import numpy as np

Tare da shigo da NumPy, yanzu zaku iya amfani da aikin asarray_chkfinite:

input_list = [1, 2, 3, 4, 5]
output_array = np.asarray_chkfinite(input_list)

Bayanin mataki-mataki na Code

Yanzu bari mu rushe lambar don ƙarin fahimtar yadda aikin ke aiki:

1. Da farko, shigo da ɗakin karatu na NumPy ƙarƙashin sunan 'np' don sauƙin shiga:

import numpy as np

2. Na gaba, ayyana lissafin shigarwa, wanda, a cikin wannan misali, ya ƙunshi ƙididdiga masu ƙima daga 1 zuwa 5:

input_list = [1, 2, 3, 4, 5]

3. A ƙarshe, yi amfani da aikin asarray_chkfinite zuwa lissafin shigarwa don canza shi zuwa tsararrun NumPy, kuma adana sakamakon a cikin madaidaicin da ake kira 'output_array':

output_array = np.asarray_chkfinite(input_list)

Yanzu kuna da tsarin NumPy, 'output_array', mai ɗauke da abubuwan asalin lissafin. Idan da akwai wasu ƙima marasa iyaka a cikin lissafin, shirin zai ɗaga Kuskuren Ƙimar, yana faɗakar da ku batun.

Ayyuka masu alaƙa a cikin Laburaren NumPy

Laburaren NumPy yana fasalta ayyuka iri-iri masu alaƙa da sarrafa tsararru, wasu daga cikinsu suna da alaƙa da aikin asarray_chkfinite:

• asara: Wannan aikin shine aikin tushe don canza lissafin shigarwa ko tuples zuwa tsararrun NumPy. Bambanci tsakanin asarray da asarray_chkfinite shine cewa asarray baya duba ko abubuwan suna da iyaka.
• asscalar: Wannan aikin yana jujjuya tsararrun abubuwa guda ɗaya na NumPy zuwa ƙimar sikeli. Zai iya zama taimako idan kuna buƙatar cire ƙima ɗaya daga cikin tsararru don ƙididdigewa ko kwatance.
• kwafi: Wannan aikin yana ƙirƙirar sabon tsarin NumPy dangane da wanda yake akwai, tare da kwafi abinda ke ciki. Wannan yana da amfani lokacin da kake son ƙirƙirar sabon tsararru daga wanda yake da shi yayin da yake tabbatar da cewa asalin tsararrun ya kasance ba a gyara ba.

A taƙaice, ɗakin karatu na NumPy yana ba da ɗimbin kayan aiki don aiki tare da tsararru da matrices. Ayyukan asarray_chkfinite, musamman, hanya ce mai ƙarfi don juyar da jeri zuwa tsararru yayin tabbatar da amincin bayanai ta hanyar bincika ƙima mai iyaka. Ta hanyar ƙware waɗannan ayyukan, zaku iya sarrafa tsararraki da kyau a cikin ayyukan Python ɗin ku kuma tabbatar da cewa bayananku suna da tsabta kuma abin dogaro, a ƙarshe yana haifar da ingantaccen bincike da ƙarshe.
