Zurfafa Zurfafa cikin Python Vs Perl Muhawara - Menene zan Koyi Python ko Perl?

Sau da yawa idan aka bullo da wani sabon harshe na shirye-shirye, akan yi muhawarar da ke farawa tsakanin wasu masu hazaka a cikin masana'antar da ake kwatanta harshen da wanda ya riga ya yada tushensa. Wani nau'i na buzz sau da yawa yana yaduwa a cikin masana'antar IT kuma ana kwatanta sabon sau da yawa akan kowane fanni yana iya zama fasali, syntax ko core CPU da abubuwan ƙwaƙwalwar ajiya ciki har da lokacin GC da duka, tare da wanzuwar irinsa.

Python vs Perl - Abubuwan da aka kwatanta

Bari mu nutse cikin wannan muhawara kuma mu yi ƙoƙari mu gano gaba ɗaya abubuwan da waɗannan harsuna biyu suka bambanta da juna. Har ila yau, bari mu gwada gano tushen gaskiya ga yawancin cliches waɗanda za a iya ji a cikin masana'antu suna cewa Python is Perl with training wheels ko Python yana kama da Perl amma ya bambanta don mu gwada mu ƙare tare da ingantacciyar mafita ga wannan muhawarar da ba ta karewa.

Python yana ɗaukar babbar fa'ida akan Perl idan ya zo ga karanta lambar. Lambar Python ta fi bayyana a fili fiye da na Perl koda lokacin karanta lambar bayan shekaru.

Tare da shigar da ke wakiltar toshe lambar, da ingantaccen tsari, lambar Python ta fi tsafta. A gefe guda, Perl yana aro tsarin haɗin gwiwa daga harsunan shirye-shirye daban-daban kamar C, sed filters idan ya zo ga maganganun yau da kullun.

Baya ga wannan, tare da '{' da '}' suna wakiltar shingen lamba da ƙari mara amfani na ';' a ƙarshen kowane layi, lamba a cikin Perl na iya zama matsala don gane idan kun karanta ta bayan watanni ko shekaru saboda izinin rubutun mummuna.

Harshen Perl yana aro tsarinsa daga C da sauran umarnin UNIX kamar sed, awk, da sauransu saboda wanda yake da ƙarfi da ginanniyar tallafin regex ba tare da shigo da kowane nau'ikan ɓangare na uku ba.

Hakanan, Perl na iya sarrafa ayyukan OS ta amfani da ayyukan ginanniyar. A gefe guda kuma, Python yana da ɗakunan karatu na ɓangare na uku don duka ayyukan biyu wato re for regex da os, sys don ayyukan os waɗanda ke buƙatar tabbatar da su kafin yin waɗannan ayyukan.

Ayyukan Perl's regex suna da 'sed' kamar syntax wanda ke sauƙaƙa ba kawai don ayyukan bincike ba amma har ma maye gurbin, maye gurbin da sauran ayyukan akan kirtani za a iya yi cikin sauƙi da sauri fiye da python inda mutum ke buƙatar sanin da tuna ayyukan da ke kula da su. bukata.

Misali: Yi la'akari da shirin don nemo lambobi a cikin kirtani a cikin Perl da Python.

Import re
str = ‘hello0909there’
result = re.findall(‘\d+’,str)
print result

$string =  ‘hello0909there’;
$string =~ m/(\d+)/;
print “$& \n”

Kuna ganin rubutun ga Perl yana da sauƙi kuma yana da wahayi ta hanyar sed umarni wanda ke cin gajiyar tsarin Python wanda ke shigo da tsarin ɓangare na uku 're'.

Ɗayan fasalin da Python ya mamaye Perl shine haɓakar shirye-shiryenta na OO. Python yana da babban tallafin shirye-shiryen da ya dace da abu tare da tsaftataccen tsari mai tsafta yayin da abin OOP a cikin Perl ya tsufa inda ake amfani da kunshin a madadin azuzuwan.

Har ila yau, rubuta OO code a cikin Perl zai ƙara daɗaɗa da yawa ga lambar, wanda a ƙarshe zai sa lambar ta yi wahalar fahimta, hatta ƙananan abubuwan da ke cikin Perl suna da matukar wahala a tsara su kuma a ƙarshe suna da wuyar fahimta daga baya.

A gefe guda, Perl ya fi dacewa don masu layi guda ɗaya waɗanda za a iya amfani da su akan layin umarni don yin ayyuka daban-daban. Hakanan, lambar Perl na iya ƙarshe yin ayyuka daban-daban a cikin ƙananan layin lamba fiye da Python.

Misalin gajeriyar lambar yarukan biyu wanda ke nuna ikon Perl na yin ƙari a cikin ƙasan LOC:

open(FILE,”%lt;inp.txt”) or die “Can’t open file”;
while(<FILE>) {

Ribobi da Fursunoni - Python vs Perl

A cikin wannan sashe, za mu tattauna Ribobi da Fursunoni na Python da Perl.

  1. Yana da tsattsauran ra'ayi mai kyau wanda ya sa wannan yaren ya zama babban zaɓi a matsayin yaren shirye-shirye na farko ga novice waɗanda ke son yin amfani da kowane yaren shirye-shirye.
  2. Yana da ci gaba sosai kuma na asali OO Programming, kuma zaren shirye-shirye a Python ya fi Perl.
  3. Akwai wuraren aikace-aikacen da yawa da Python ya fi so kuma har ma ya fi Perl. Kamar: An fi son Perl don rubutun CGI amma a zamanin yau Python's Django da web2py kamar harsunan rubutun yanar gizo sun zama sananne kuma suna da sha'awar masana'antu.
  4. Yana da SWIG wrappers da yawa don harsunan shirye-shirye daban-daban kamar CPython, IronPython da Jython kuma ci gaban waɗannan ya riga ya haɓaka SWIG wrappers don Perl.
  5. Python code yana da kyau koyaushe kuma yana da sauƙin karantawa da fahimta ko da kuna karanta lambar wani ko ma lambar ku bayan shekaru.
  6. Python yana da kyau ga aikace-aikace daban-daban kamar Big Data, Infra Automation, Injin Learning, NLP, da dai sauransu, yana da babban tallafi na al'ummomin da ke aiki saboda kasancewar Buɗe tushen.

  1. Akwai ƴan wuraren da aiwatar da aiwatarwa a Python yawanci yakan yi hankali fiye da na Perl ciki har da regex da ayyukan tushen kirtani.
  2. Wani lokaci yana da wahala a sami nau'in variable a Python kamar yadda a lokuta na manyan code, dole ne ku tafi har zuwa ƙarshe don samun nau'in canjin da ke daɗaɗaɗawa da rikitarwa.

    Perl yana da masu yin layi ɗaya masu ƙarfi kuma har ma yana tabbatar da bututun UNIX kamar syntax wanda za'a iya amfani dashi akan layin umarni don aiwatar da ayyuka daban-daban, kuma Unix da shirye-shiryen layin umarni sun rinjayi shi don haka yana haɗa umarni da yawa na UNIX a cikin coding ɗin sa. . Perl sananne ne don regex mai ƙarfi da ayyukan kwatanta kirtani kamar yadda sed da awk ke tasiri kamar kayan aikin UNIX masu ƙarfi. A cikin yanayin regex da ayyukan kirtani kamar maye gurbin, daidaitawa, sauyawa, Perl ya fi Python wanda zai ɗauki ƴan layukan lamba don cimma iri ɗaya. Hakanan yawancin ayyukan I/O na fayil, ban da kulawa ana yin sauri akan Perl.
  1. Lokacin da ya zo ga harshe don samar da rahoto, Perl ya kasance sananne tun lokacin da aka gabatar da shi a matsayin daya daga cikin manyan dalilan da ya sa marubucin ya bunkasa harshe kamar Perl ya kasance don samar da rahoto.
    2. Yawancin wuraren aikace-aikacen da Perl ya sami amfani da shi shine Network Programming, System Administration, CGI Scripting (a nan Python yana cin nasara akan Perl tare da Django da web2py), da sauransu.

    Perl yana da hadadden lamba wanda ke sa ya zama da wahala a fahimta ga novice. Subroutines, har ma da sauran alamomin kamar: '$\', '$&' da sauransu suna da wahalar fahimta da kuma tsara shirye-shirye don ƙarancin ƙwararrun mawallafi. Har ila yau, Perl code lokacin da karantawa zai yi wuya da wuyar fahimta sai dai idan kuna da kwarewa mai inganci.
  1. OO Programming in Perl ya ɗan ƙare saboda ba a taɓa saninsa da shirye-shiryen OO ba kuma yawancin ayyuka kamar zaren zaren suma ba a bayyana su akan Perl.

Kamar yadda aka gani a sama inda duka harsunan biyu suke da kyau a kan su dangane da aikace-aikacen da suka yi niyya, Python yana ɗaukar ɗan fa'ida akan Perl a matsayin zaɓi na farko ga novice saboda tsabta da sauƙin fahimtar lambar, yayin da a gefe guda Perl ya zarce Python. idan ya zo ga ayyukan magudin kirtani da wasu ci-gaba ɗaya-liners don UNIX kamar OS da sauran ayyuka daban-daban da aka san shi da su.
