An warware: NumPy trim_zeros Misali lokacin datsa%3D%27b%27

NumPy babban ษ—akin karatu ne mai buษ—ewa a cikin Python wanda ke sauฦ™aฦ™e ฦ™ididdige ฦ™ididdigewa ta hanyar samar da ฦ™aฦ™ฦ™arfan tsarin ayyuka da kayan aiki don aiwatar da ayyukan lissafi akan manyan tsararru da matrices masu girma dabam. Daga cikin ayyuka daban-daban da ake da su a cikin NumPy, ษ—ayan ฦ™arancin sanannun amma fasali mai fa'ida shine ikon cire jagora da/ko sifilin sifili daga tsararraki. Wannan fasalin zai iya zama mai taimako musamman a duniyar salon, inda daidaito da inganci ke da mahimmanci wajen ฦ™ira da gina riguna, tsarin launi, da alamu.

A cikin wannan labarin, za mu nutse cikin cikakken misali na yadda ake amfani da NumPy's datsa_zeros aiki tare da takamaiman mayar da hankali kan datsa ='b' siga. Bugu da ฦ™ari, za mu tattauna aikin lambar kuma za mu ba da cikakken bayani game da ษ—akunan karatu da ayyukan da ke cikin matsala.

Da farko, bari mu yi la'akari da matsalar da muke son warwarewa. A ce kuna da ma'aunin ma'aunin tufa, inda kowane kashi yana wakiltar takamaiman tsayi ko faษ—i cikin santimita. ฦ˜imar da ke cikin tsararrun ฦ™ila ta ฦ™unshi sifili masu jagora da masu bin diddigi saboda rashin daidaiton aunawa ko kuskuren ษ—an adam. Manufar ita ce a cire waษ—annan sifilai marasa mahimmanci daga ma'auni don ฦ™irฦ™irar ingantaccen tsarin bayanai.

Mu dauki wannan tsararru a matsayin misali:

import numpy as np

measurements = np.array([0, 0, 25, 42, 55, 0, 60, 0])

Yanzu, muna so mu cire duka biyun jagora da sifili ta amfani da aikin trim_zeros da aka yi amfani da shi tare da sigar datsa ='b'. Maganin wannan matsala shine kamar haka.

trimmed_measurements = np.trim_zeros(measurements, trim='b')

print(trimmed_measurements)

Da fitarwa zai zama:

array([25, 42, 55, 0, 60])

Fahimtar Code

Bari mu zurfafa zurfafa cikin yadda lambar ke aiki don ฦ™arin fahimtar abubuwan da ke cikin tushe da ayyukan da ke ciki. Abu na farko da muka yi shi ne shigo da ษ—akin karatu na NumPy da ฦ™irฦ™irar tsarar ma'aunin misali.

Bayan haka, mun yi amfani da aikin trim_zeros tare da sigar 'b'. Ma'aunin datsa yana ษ—aukar ษ—aya daga cikin ฦ™ima guda uku masu yiwuwa: 'f' (don cire sifilai masu jagora), 'b' (don cire sifilai masu biyo baya), da 'fb' (don cire duka biyun jagora da sifili). A cikin yanayinmu, mun zaษ“i 'b' saboda muna son cire sifilin da ke biyo baya kawai.

A ฦ™arshe, bayan aiwatar da aikin trim_zeros, yana sabunta tsararrun ma'auni ba tare da sifili masu biyo baya ba kuma yana buga tsararrun da aka gyara.

Ayyukan NumPy da Laburaren da ke da alaฦ™a

Yanzu da muka fahimci matsalar da muka warware da kuma yadda lambar ke aiki, bari mu ษ—an duba ayyukan NumPy da ษ—akunan karatu masu alaฦ™a waษ—anda ke da alaฦ™a da aikin trim_zeros.

  • nupy.asarray(): Wannan aikin yana kama da numpy.array(), amma yana da ฦดan zaษ“uษ“ษ“uka kuma baya yin kwafin bayanan shigarwa idan bayanan shigarwa ya riga ya zama ndarray ko pandas.Series.
  • numpy.concatenate(): Yana ba ka damar haษ—a nau'i biyu ko fiye tare da axis data kasance.
  • nupy.delete(): Ana amfani da wannan aikin don share abubuwa daga tsararru tare da ฦ™ayyadadden axis bisa ga fihirisar element.

Baya ga ษ—akin karatu na NumPy, akwai wasu ษ—akunan karatu na Python waษ—anda za su iya taimakawa wajen magance irin waษ—annan matsalolin, kamar Pandas don sarrafa bayanai da Scikit-koyi don algorithms koyon injin.

Ta wannan misalin da bayanin, muna fatan kun sami kyakkyawar fahimtar yadda ake amfani da aikin NumPy's trim_zeros tare da ma'aunin 'b', da kuma yadda za'a iya amfani da shi a fagen sarrafa bayanan salo. Ta hanyar ฦ™ware waษ—annan mahimman shirye-shiryen Python da dabarun SEO, zaku iya haษ“aka ฦ™warewar coding ษ—in ku kuma ฦ™irฦ™irar ingantacciyar mafita, ingantacciyar mafita ga ษ—imbin matsaloli.
