Python ile Matrix Rain Etkisi Yaratmak

İncelediğimiz kod ile Matrix filmlerindeki, düşen harflerle yaratılan etkiyi yeniden oluşturuyoruz.

Orijinal kodları: https://gist.github.com/MrKioZ/c07b9377d20bab53af6ebcdfbdeabb64 adresinde bulabilirsiniz.

Aşağıdaki kodlar kısaltılmış ve bazı eklentiler yapılmış halidir.
