• Variables (Types & Calculation)
• Control flow statements (if, while, for, pass, continue, break, return)
• Functions (Built-in functions, how to write and use a function)

This notebook is mainly about Data Structures of Python, which contains:

• Tuple (definition, indexing, function)
• Set (definition, function)
• Dictionary (definition, indexing with keys, function)
• Summary (Sequence(List, tuple, string) - indexing & Slicing, Reference (Direct Reference & Indirect Reference), Functions of strings)
