Python Functions: In python, function is a group of related statements that perform a specific task. A function is a block of organized, reusable cod that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing. Types of Functions: i)Built in Functions ii) User defined Functions Built in Functions: You already know, Python gives you many built in functions like print(). User defined Function You can also create your own functions. These functions are called user defined function. Example: def swap(x,y): '''creating user temp=x define swap x=y function''' y=temp return x,y x=2 y=3 print(swap(x,y)) #calling function Outupt: (3,2) Defining a Function: Function Definition provides the information about function name, parameters and the definition what operation is to be performed. 'def...

Python Comments: A comment in python starts with the hash character(#). Comments are in the source code for humans to read, not for computers to execute. Example: #This is a comment Types of Python comments: 1)Single lined comment 2)Multi lined comment 3)Inline comments Single lined comment: In case user want to specify a single line comment,then comment must start with #. Example: int a=10 #here a is a variable. print("Hello,world") print(a) Output: Hello,world 10 Multi lined comments: Multi lined comment can be given inside triple quotes. Example: ''' This is multiline comment in python''' Inline comments: If a comment is placed on the same line as a statements,it is called an inline comments. Similar to the block comments, an inline comments beigns with a single hash(#) sign and followed by a space and comment. Example: N=10 n+=1 # increase n by 1

Operator: Operators are special symbol in python that carry out arithmatic or logical computation, Used to perform specific operation. For Example: >>>2+3 5 Types of Operator: 1. Arithmatic operator 2. Assignment operator 3. Comparison operator 4. Logical operator 5. Bitwise operator 6. Identity operator 7. Membership operator Arithmatic operator: Arithmatic operators are used to perform mathematical operation like addition,subtraction ,multiplication etc. Addition(+): Adds value on either of the operators. Example: a=10 b=20 print(a+b) Output: 30 Subtraction(-): Subtracts right hand operands form left hand oprand. Example: a=20 b=10 print(a-b) Output: 10 Multiplication(*): Multiply values on either side of the operators. Example: a=20 b=10 print(a*b) Output: 200 Division(/): divides left hand operand by right hand operand. Example: a=20 b=10 print(a/b) Output: 2 Module(%): Divides left hand operan...

Literls:- Literal is a raw data given in a variable or consatant. In python, there are various type of literls. Type of Literls:- 1. String 2. Numeric 3. Boolean 4. Special String: String is an immutable data type. String formed by enclosing a text in the qutoes. Both single and double quotes can be used. Example: string='This is python' char="C" print(string) print(char) Output: This is python C Numeric Literls: Numeric literals are immutable data type. Numeric literals can belong to four different Numeric type. Types of Numeric Literls: .Integer .Long .Float .Complex integer(signed integer): Number( can be +ve and -ve) with nuber fractional part. Example: 230 Long(long integer): Integer of unlimited size followed by lower case or uppercase. Example 8703285L Float(folating point): Real numer with both integer and fractional part. Example 35.2 Complex(complex): In the form ...
