(iv) Operators, Expressions, and Python Statements
Assignment statements, expressions, Arithmetic, Relational, Logical, Bitwise operators and their precedence, Conditional statements: if, if-else, if-elif-else; simple programs, Notion of iterative computation and control flow –range function, While Statement, For loop, break statement, Continue Statement, Pass statement, else, assert.
(v) Sequence Data Types

Lists, tuples, and dictionary, (Slicing, Indexing, Concatenation, and other operations on Sequence data type), concept of mutability, Examples to include finding the maximum, minimum, and mean; linear search on the list/tuple of numbers, and counting the frequency of elements in a list using a dictionary.
