Puthon

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.
