Multiple Choice Questions on Python for Online Safety Games

📚 Quick Study Guide

🔑 Key Concepts:
• 🌐 Input Sanitization: Cleaning user inputs to remove potentially harmful characters or code.
• 🛡️ Authentication: Verifying the identity of users to prevent unauthorized access.
• 🔒 Encryption: Converting data into a secure format that can only be read with a decryption key.
• ⚠️ Avoiding Eval(): Never use the `eval()` function with user-provided input, as it can execute arbitrary code.
• 🛑 Rate Limiting: Restricting the number of requests a user can make in a given time frame to prevent abuse.
• 📝 Data Validation: Ensuring user inputs conform to expected formats and ranges.
• 🔥 Cross-Site Scripting (XSS) Prevention: Encoding user inputs to prevent malicious scripts from running in other users' browsers.
