Basic Troubleshooting: Common Errors and Fixes

2. Control Flow

Conditional Statements: if, else, elif
Comparison and Logical Operators
Loops:
- for loops
- while loops
- Loop control statements: break, continue, pass

4. Data Structures

Lists:
- Indexing, Slicing, and Methods (append, insert, remove, etc.)
Tuples:
- Immutability and Use Cases
Dictionaries:
- Key-Value Pairs, Methods (get, keys, values, etc.)
