Python Literalleri: Detayl\u0131 Anlat\u0131m<\/p>\n
Merhaba Python severler! Bu makalede, Python programlama dilinin temel yap\u0131 ta\u015flar\u0131ndan biri olan literaller<\/strong>i (literal) detayl\u0131 bir \u015fekilde ele alaca\u011f\u0131z. Literaller, kodunuzda do\u011frudan yaz\u0131lan sabit de\u011ferlerdir. \u00d6rne\u011fin, say\u0131lar (10, 3.14), metinler (“Merhaba D\u00fcnya!”), ve Boolean de\u011ferler (True, False) literallerdir. Ancak, i\u015fin i\u00e7ine listeler, tuple’lar ve s\u00f6zl\u00fckler de girdi\u011finde durum biraz daha karma\u015f\u0131kla\u015f\u0131r. Bu makalede, t\u00fcm bu durumlar\u0131 ayr\u0131nt\u0131l\u0131 olarak inceleyece\u011fiz.<\/p>\n Python, farkl\u0131 say\u0131 tiplerini destekler. Bunlar aras\u0131nda tam say\u0131lar (integers), ondal\u0131kl\u0131 say\u0131lar (floating-point numbers) ve karma\u015f\u0131k say\u0131lar (complex numbers) bulunur. \u00d6rne\u011fin:<\/p>\n Tam say\u0131lar (integers) herhangi bir b\u00fcy\u00fckl\u00fckte olabilir. Ondal\u0131kl\u0131 say\u0131lar ise, ondal\u0131k noktas\u0131ndan sonra virg\u00fclden sonraki basamaklar\u0131 g\u00f6sterir. Karma\u015f\u0131k say\u0131lar ise, ger\u00e7ek ve sanal k\u0131s\u0131mdan olu\u015fur. Bunlar\u0131n hepsi, kodumuzda do\u011frudan yaz\u0131labilen ve belirli bir de\u011feri temsil eden literallerdir. Ayr\u0131ca, farkl\u0131 tabanlardaki (\u00f6rne\u011fin, onalt\u0131l\u0131k, sekizlik) say\u0131lar\u0131 da ifade edebiliriz.<\/p>\n Metinler, tek t\u0131rnak (\u2018 \u2019) veya \u00e7ift t\u0131rnak (\u201c \u201d) i\u00e7inde yaz\u0131l\u0131r. \u00d6rne\u011fin:<\/p>\n \u00dcstelik, \u00fc\u00e7l\u00fc t\u0131rnaklar (”’ ”’ veya “”” “””) kullan\u0131larak \u00e7ok sat\u0131rl\u0131 metinler de tan\u0131mlanabilir. Bu, \u00f6zellikle uzun metinleri okunabilir bir \u015fekilde yazmak i\u00e7in faydal\u0131d\u0131r. Ayr\u0131ca, escape karakterleri (\\n, \\t vb.) metin i\u00e7inde \u00f6zel karakterleri temsil etmemize olanak tan\u0131r.<\/p>\n Boolean (mant\u0131ksal) de\u011ferler, True (do\u011fru) ve False (yanl\u0131\u015f) olarak tan\u0131mlan\u0131r. Bu de\u011ferler, ko\u015fullu ifadelerde ve mant\u0131ksal i\u015flemlerde kullan\u0131l\u0131r.<\/p>\n Python, \u00e7e\u015fitli veri yap\u0131lar\u0131na sahiptir ve bunlar da literallerle ifade edilebilir. Listeler k\u00f6\u015feli parantezler ([ ]), tuple’lar yuvarlak parantezler (( )) ve s\u00f6zl\u00fckler s\u00fcsl\u00fc parantezler ({ }) kullan\u0131larak olu\u015fturulur.<\/p>\n Listeler de\u011fi\u015ftirilebilir, s\u0131ral\u0131 veri yap\u0131lar\u0131d\u0131r. Tuple’lar ise de\u011fi\u015ftirilemez, s\u0131ral\u0131 veri yap\u0131lar\u0131ndand\u0131r. S\u00f6zl\u00fckler ise anahtar-de\u011fer \u00e7iftlerinden olu\u015fan, s\u0131ras\u0131z veri yap\u0131lar\u0131ndan biridir.<\/p>\n Python’daki literaller, programlamada temel yap\u0131 ta\u015flar\u0131d\u0131r. Bu makalede, farkl\u0131 literal tiplerini ve nas\u0131l kullan\u0131ld\u0131klar\u0131n\u0131 inceledik. Umar\u0131m bu bilgiler Python yolculu\u011funuza yard\u0131mc\u0131 olmu\u015ftur.
