Python Terms
Python uses many of the same concepts as JavaScript, but with cleaner syntax. Here are the Python-specific terms.
| English | Türkçe |
|---|---|
| printprint('Hello') shows text on screen. | yazdırmakprint('Hello') ekranda metin gösterir. |
| defdef means 'define a function'. | tanımladef, 'fonksiyon tanımla' anlamına gelir. |
| listA list is like a JavaScript array: [1, 2, 3]. | listeListe, JavaScript'teki dizi (array) gibidir: [1, 2, 3]. |
| dictionaryA dictionary stores key-value pairs: {'name': 'Elif'}. | sözlükDictionary (sözlük), anahtar-değer (key-value) çiftlerini tutar: {'name': 'Elif'}. |
| indentPython uses indentation (spaces) instead of curly braces. | girintiPython, süslü parantezler yerine girintileme (boşluklar) kullanır. |
| importimport lets you use code from other files. | içe aktarmakimport, başka dosyalardaki kodları kullanmanı sağlar. |
| rangerange(5) creates numbers 0, 1, 2, 3, 4. | aralıkrange(5), 0, 1, 2, 3, 4 sayılarını oluşturur. |
| inputinput() asks the user to type something. | girdiinput(), kullanıcıdan bir şey yazmasını ister. |
Why Python?
Python is the world's most popular programming language. It's used for:
• Web development (Instagram, Spotify)
• Data science and AI (ChatGPT, TensorFlow)
• Automation (scripts that do tasks for you)
• Game development
• Scientific research
Python is known for being easy to read — it looks almost like English:
if age >= 18:
print("You can vote")
No curly braces { }, no semicolons ; — just clean, simple code.
Challenge 1: Variables and Print
Challenge 2: Functions with def
Challenge 3: Lists and Loops
Challenge 4: Dictionaries
Challenge 5: Build a Student Report Card
Now actually practise it
Reading a lesson is the easy half. A free account unlocks the parts that make it stick — listen to every word in a British accent, and use it in a live conversation with James. Your progress is saved and the words come back for review before you forget them.
