1. Basic Syntax and Structure
- Python is an interpreted, high-level, general-purpose programming language.
- Indentation is crucial in Python; it defines the scope of code blocks.
- Python uses whitespace for code organization, making it more readable than other languages.
- Common data types: integers, floats, strings, lists, tuples, dictionaries, and sets.
- Control structures: if-else, for, while, and break/continue.
2. Functions and Modules
- Define functions using the def keyword.
- Pass arguments to functions and return values using the return statement.
- Import modules using the import keyword.
- Use the import syntax to import all functions and variables from a module.
- Use the from module import name syntax to import specific functions or variables.
3. Object-Oriented Programming (OOP)
- Define classes using the class keyword.
- Use the __init__ method to initialize class attributes.
- Inherit from a base class using the inheritance syntax.
- Override methods and use super() to call base class methods.
- Use encapsulation to protect class attributes.
4. Exception Handling
- Use try-except blocks to handle exceptions.
- Use the finally block to execute code that should run regardless of whether an exception occurred.
- Customize exception handling by defining your own exception classes.
5. File Handling
- Use the open() function to open a file.
- Read and write files using the read(), write(), and seek() methods.
- Use the with statement to ensure that files are properly closed after use.
6. Common Python Libraries
- NumPy: For numerical computations.
- Pandas: For data manipulation and analysis.
- Matplotlib: For data visualization.
- Scikit-learn: For machine learning algorithms.
- Flask and Django: For web development.
By familiarizing yourself with this Python interview cheat sheet, you’ll be well-equipped to tackle the most challenging questions during your interview. Good luck, and happy coding!
