Python Temelleri: De\u011fi\u015fkenler, Veri T\u00fcrleri ve Temel Operat\u00f6rler<\/p>\n
Python, d\u00fcnyada en pop\u00fcler programlama dillerinden biridir ve geni\u015f bir uygulama alan\u0131na sahiptir. Bu makalede, Python programlaman\u0131n temel ta\u015flar\u0131n\u0131 ele alarak, de\u011fi\u015fkenleri, veri t\u00fcrlerini ve temel operat\u00f6rleri ke\u015ffedece\u011fiz. Bu konular\u0131 anlamak, Python yolculu\u011funuza sa\u011flam bir temel sa\u011flayacakt\u0131r.<\/p>\n
De\u011fi\u015fkenler, program\u0131m\u0131zda de\u011ferleri depolamak i\u00e7in kullan\u0131lan isimlerdir. De\u011fi\u015fkenler, verileri organize etmek ve kodun okunabilirli\u011fini art\u0131rmak i\u00e7in olmazsa olmazd\u0131r. Python’da de\u011fi\u015fken tan\u0131mlamak olduk\u00e7a basittir. Sadece de\u011fi\u015fken ad\u0131n\u0131 yaz\u0131p, e\u015fitlik (=) i\u015fareti ile ard\u0131ndan de\u011ferini yazar\u0131z.<\/p>\n
“`python
\nname = “Fatih”
\nage = 30
\nis_programmer = True

Yukar\u0131daki \u00f6rnekte, `name`, `age` ve `is_programmer` de\u011fi\u015fkenlerini tan\u0131mlad\u0131k. `name` de\u011fi\u015fkeni bir string de\u011ferini, `age` de\u011fi\u015fkeni bir tam say\u0131 de\u011ferini ve `is_programmer` de\u011fi\u015fkeni bir boolean de\u011ferini temsil eder.<\/p>\n
Veri t\u00fcrleri, program\u0131m\u0131zda kullan\u0131lan de\u011ferlerin t\u00fcrlerini tan\u0131mlar. Python, farkl\u0131 veri t\u00fcrlerini destekler. En s\u0131k kullan\u0131lanlar\u0131 \u015funlard\u0131r:<\/p>\n
