METODLAR
Ilovalarni Python dasturlash tilida ishlab chiqish jarayonida uning imkoniyatlaridan toʻliq foydalanish maqsadida bir qator savollarga javob topish zaruriyati yuzaga keladi:

1. 
   Python qanday modullari oʻz ichiga oladi?
   
2. 
   Har bir modul qanday sohaga xizmat qiladi?
   
3. 
   Har bir modul qanday metod va funksiyalarni oʻz ichiga oladi?
   

Dastlabki ikkita savolga javob berish uchun Pythom modullarini sinflashtirish talab qilinadi. Uchinchi savolga dasturchilar soha va modul nomi ma’lum boʻlgani uchun, ehtiyojariga ko’ra osongina javob topa oladilar.
Predmetga yoʻnaltirligan dasturlash nuqtai nazaridan sinflashtirish yuzasidan olib borgan tahlillarimiz Python dasturlash tilining ichki modullari 24 ta sohaga mansub oid tipik masalalarni qamrab olganini koʻrsatdi. Bunda sinflashtirish D. Xellmanning “Стандартная библиотека Python 3: справочник с примерами” nomli kitobi [2], pypi.org [3], kite.com [4] saytlari va IDLE ning yordamchi tizimida bayon etilgan ma’lumotlar asosida amalga oshirildi.
Python tili standart modullarini sinflashtirish uchun D. Xellman taklif qilgan gʻoyalar asos sifatida qabul qilindi. D. Xellman oʻz kitobida 117 ta modullarni tahlil qilib, ularni 19 ta sinfga ajratgan va har bir sinfga kirgan metod va funksiyalar bayon qilgan. Bu sinflar qolgan 200 ga yaqin modullar ustidagi shaxsiy tahlillar asosida boyitildi va qoʻshimcha 5 ta sinf hisobiga kengaytirildi (1.1-jadval).
