# Python Veri Tiplerine Giriş

Python isteğe bağlı olarak "tip belirteçlerini" destekler.

 **"Tip belirteçleri"** bir değişkenin <abbr title="örneğin: str, int, float, bool">tipinin</abbr> belirtilmesine olanak sağlayan özel bir sözdizimidir.

Değişkenlerin tiplerini belirterek editör ve araçlardan daha fazla destek alabilirsiniz.
