Python boleh digunakan dalam banyak arah, seperti perangkak, analisis ramalan, GUI, automasi, pemprosesan imej, visualisasi, dll. Ia mungkin hanya memerlukan sedozen baris kod untuk mencapai fungsi yang hebat.
Oleh kerana Python ialah bahasa skrip dinamik, logik kod adalah jauh lebih mudah daripada Java, dan lebih sedikit kod perlu ditulis untuk mencapai fungsi yang sama. Selain itu, ekosistem Python mempunyai banyak perpustakaan alat pihak ketiga yang merangkum fungsi dalam pakej Anda hanya perlu memanggil antara muka untuk menggunakan fungsi yang kompleks.
Berikut ialah beberapa contoh skrip yang mudah dan menyeronokkan Pemula boleh mengikuti kod dan menguasai sintaks python dengan cepat.
