Did you mean Python? I can help with Python exam prep. Tell me a bit more to tailor it: - What level is the exam (intro CS, data structures, algorithms, data science)? - Which topics do you need to review (basics, control flow, functions, OOP, data structures, file I/O, testing, libraries)? - Do you want explanations, practice problems with answers, or debugging help? If you want something right away, here’s a quick Python refresher with tiny examples: - Print and basics: print("Hello, Python!") - Variables: x = 5, y = 2.7, name = "Alice" - Types: int, float, str, bool - Data structures: - Lists: nums = [1, 2, 3]; nums.append(4) - Tuples: t = (1, 2, 3) - Dictionaries: d = {"a": 1, "b": 2}; d["a"] = 10 - Sets: s = {1, 2, 3} - Control flow: - If: if x > 0: print("positive") - For: for n in nums: print(n) - While: while x < 10: x += 1 - Functions: - def add(a, b): return a + b - Default args: def greet(name, msg="Hello"): print(f"{msg}, {name}") - List/dict/set comprehensions: - squares = [i*i for i in range(10)] - kv = {i: i*i for i in range(5)} - File I/O: - with open("data.txt", "r") as f: data = f.read() - Exceptions: - try: risky(); except ValueError: handle() - Classes (OOP): - class Dog: def __init__(self, name): self.name = name - Common gotchas: - Mutable default args: def add_to_list(x, lst=None): if lst is None: lst = []; lst.append(x); return lst - Avoid shadowing built-ins (e.g., list, dict) - Useful libraries (standard): math, random, itertools, functools - Quick quiz idea (practice): write a function to count vowels in a string; write a function that returns the factorial of n without recursion; sort a list of dictionaries by a key. Would you like me to: - generate a set of practice questions (with solutions)? - create a 3- or 7-day study plan tailored to your topics? - walk through specific topics or debug a piece of Python code you’re stuck on? Tell me your preferences and any topics you want covered first.
