A variable in a program gives data to the computer. EXPRESSIONS  An Expression is a combination of values, variables and operators. STATEMENTS  A Statement is an instruction that a python interpreter can execute.IN python end of a statement is marked by a newline character.  c=a+b  Multiline statement can be used in single line using semicolon(;) Difference between a Statement and an Expression  A statement is a complete line of code that performs some action, while an expression is any section of the code that evaluates to a value.  Expressions can be combined ―horizontally into larger expressions using operators, while statements can only be combined vertically by writing one after another, or with block constructs.  Every expression can be used as a statement, but most statements cannot be used as expressions COMMENTS  Comments are non-executable statements which explain what program does. There are two ways to represent a comment.  Single Line Comment  Begins with # hash symbol  Multi Line Comment  Multi line comment begins with a double quote and a single quote and ends with the OPERATORS:  Operators are the construct which can manipulate the value of operands. Types of Operator:  1. Arithmetic Operator  2. Comparison Operator (or) Relational Operator  3. Assignment Operator  4. Logical Operator  5. Bitwise Operator  6. Membership Operator  7. Identity Operator If more than one operator exists in the same group. These operators have the same precedence. When two operators have the same precedence, associativity helps to determine which the order of operations. Associativity is the order in which an expression is evaluated that has multiple operator of the same precedence. Almost all the operators have left-to-right associativity. For example, multiplication and floor division have the same precedence. Hence, if both of them are present in an expression, left one evaluates first
