Q.11: Data items having fixed values are called Literals

Q.12:Operators are  tokens that trigger some computation when applied to variables  and other objects in an expression.

 

Q.13:Output :

Answer : 15

                13   22

 

Q.14:Output

Q.15: How are string-literals represented and implemented in Python ?

Answer : A string-literal is represented as a sequence of characters surrounded by quotes (single, double or triple quotes). String-literals in Python are implemented using Unicode.

 

Q.16: What do you mean by dynamic typing ?

Answer : A variable pointing to a value of a certain type , can be made to point to a value of different type . This is called dynamic typing

.

Q.17:What is the use of indentation in Python ?

Answer :  Python uses indentation to create block of code. Statements at same indentation level are part of same block/suite.

 

Q.18: What is typecasting? Explain with example

Answer: Converting one datatype into another is known as type casting or, type-conversion. For example, if you want to store a ‘long’ value into a simple integer then you can type cast ‘long’ to ‘int’. You can convert the values from one type to another explicitly using the cast operator as follows − (type_name) expression.

 

Q.19: What are operators ? What is their function ? Give examples of some unary and binary operators.

Answer :  Operators are tokens that trigger some computation/action when applied to variables and other objects in an expression. Unary plus (+), Unary minus (-), Bitwise complement (~), Logical negation (not) are a few examples of unary operators. Examples of binary operators are Addition (+), Subtraction (-), Multiplication (*), Division (/).

 

Q.20: Define:

a) Expressions

Answer: Expressions is any legal combination of symbols that represent value

 

b) Statements

Answer: A statement is a programming instruction that does something i.e. some action takes place

 

c) Comments

Answer : Comments are the additional readable information to clarify the source code, which is read by the programmers but ignored by the interpreter.
