• Variables: initialization (int, float, string), overriding variables with the same name, execution of arithmetic operations (* / - +), support order of operations.
• Dictionaries: initialization(keys: primitive types, values: everything), implementation of items() and setdefault(keyname, value=None) functions.
• print(): implementation of the function. Fully compatible with variables and dictionaries.

• Comments
• Modules Import
• Classes: definition, constructor definition, object creation.
• Functions: definiction, call.
• Conditional Statements: if, elif, else.
• For Loops
• Lambda Functions
