An warware: Don canza kwanan wata dtypes daga Abun zuwa ns%2CUTC tare da Pandas

Pandas kayan aiki ne mai mahimmanci a cikin duniyar sarrafa bayanai da bincike yayin aiki tare da Python. Sassaucinsa da sauฦ™in amfani ya sa ya dace da ayyuka masu yawa da suka shafi sarrafawa da nazarin bayanai. Matsala ษ—aya ta gama gari da ake fuskanta lokacin aiki tare da Pandas shine canza nau'in kwanan wata daga Abu zuwa ns tare da yankin lokacin UTC. Wannan juyawa ya zama dole saboda, a wasu bayanan bayanai, ba a gane ginshiฦ™an kwanan wata azaman dtypes ta tsohuwa kuma a maimakon haka ana ษ—aukar abubuwa. Wannan na iya haifar da al'amura yayin ฦ™oฦ™arin yin ayyuka kamar rarrabawa, tacewa, da haษ—awa. A cikin wannan labarin, za mu bincika wannan batu na musamman da kuma samar da mafita don sauฦ™in sauya dtype na ginshiฦ™an kwanan wata daga Object zuwa ns (UTC) ta amfani da Pandas, yana rufe mataki-mataki mataki don fahimtar lambar.

Gabatarwa zuwa Pandas da Aiki tare da Kwanan Wata

Pandas babban ษ—akin karatu ne mai buษ—e ido wanda ke ba da damar sauฦ™in jujjuyawa, magudi, da nazarin bayanai. Yana ba da tsarin bayanai, kamar DataFrame da Series, waษ—anda ke sa aiki tare da bayanai a Python ya fi dacewa da fahimta. Lokacin da ake hulษ—a da bayanan jerin lokaci, Pandas yana zuwa tare da ayyuka iri-iri da aka tsara don yin aiki tare da kwanan wata, lokuta, da bayanan lokaci-ฦ™ididdiga.

Koyaya, lokacin shigo da irin wannan bayanan daga tushe daban-daban, kamar fayilolin CSV ko Excel, Pandas bazai gane ginshiฦ™an kwanan wata da kyau ba. Wannan yana haifar da ษ—aukar kwanakin a matsayin abubuwa, iyakance ayyukansu da sanya su rashin dacewa don ฦ™arin ฦ™ididdiga da ayyuka masu alaฦ™a da kwanan wata.

Magani: Canza kwanan wata dtypes daga Object zuwa ns (UTC) tare da Pandas

Maganin wannan matsalar ita ce canza ginshiฦ™an kwanan wata a sarari daga Abu zuwa tsarin kwanan wata da ake so (a wannan yanayin, ns tare da yankin lokacin UTC) ta amfani da Pandas. Ana iya samun wannan ta hanyar pd.zuwa_kwanan lokaci() aiki, wanda ke ba da damar sauฦ™in sauyawa na ginshiฦ™an kwanan wata.

import pandas as pd

# Load the CSV file
data = pd.read_csv('data.csv')

# Convert the date column from Object to ns (UTC)
data['date_column'] = pd.to_datetime(data['date_column'], utc=True, format='%Y-%m-%d')

# Print the DataFrame with the updated dtype for the date column
print(data.dtypes)

Bayanin mataki-mataki na Code

  • Shigo da ษ—akin karatu na Pandas tare da laฦ™abi pd.
  • Load da fayil ษ—in CSV mai ษ—auke da bayanan tare da pd.read_csv() aiki.
  • Maida ginshiฦ™in kwanan wata ta amfani da pd.zuwa_kwanan lokaci() aiki, wucewa ginshiฦ™in sha'awa tare da yankin lokaci da ake so (utc=Gaskiya) da tsari (idan ya cancanta).
  • Buga dtypes na DataFrame don tabbatar da cewa an sami nasarar sauya ginshiฦ™in kwanan wata daga Abu zuwa ns (UTC).

ฦ˜arin Nasiha da Mafi kyawun Ayyuka

Pandas yana ba da hanyoyi da ayyuka da yawa don sarrafa ranaku da lokuta. Anan akwai ฦ™arin nasiha da mafi kyawun ayyuka da ya kamata a bi yayin mu'amala da ginshiฦ™an kwanan wata:

  • Koyaushe bincika dtypes na ginshiฦ™an ku bayan shigo da saitin bayanai don tabbatar da suna cikin tsari daidai.
  • Idan aiki tare da lokutan lokaci, yi la'akari da amfani da pytz ษ—akin karatu don ฦ™arin zaษ“uษ“ษ“ukan gudanarwa na yankin lokaci.
  • Don shari'o'in amfani na yau da kullun, ba koyaushe ya zama dole don canza dtype ษ—in ginshiฦ™in kwanan wata zuwa nanoseconds (ns). Tsoffin dtype da Pandas ke amfani da shi (datetime64[ns]) yakan isa.

Ta bin wannan jagorar da fahimtar tsarin jujjuya dtypes na kwanan wata daga Object zuwa ns (UTC) ta amfani da Pandas, zaku iya tabbatar da cewa an tsara bayanan jerin lokutanku yadda yakamata kuma a shirye don ฦ™arin magudi da bincike. Wannan ba kawai yana sauฦ™aฦ™a lokacin ฦ™addamar da bayanai ba amma kuma yana ba da damar ฦ™arin ingantaccen bincike mai inganci. Tare da ฦ™waฦ™ฦ™waran fahimtar waษ—annan fasahohin, za ku kasance da wadatattun kayan aiki don magance jerin lokaci a ayyukanku na gaba.
