Python Operators and Conversions

 Python Operator :

Operator are very necessary for any programming language for do mathematical function . With out mathematical function you can not add any logic into programming code .Logic of any programming language is the main portion which is soul of any programming language . There is similar operator in python like other programming language .

• Arithmetic Operator

      + : plus

      - : minus

      / : slash

      * : asterisk

      % : percent

     There is another arithmetic operators which are ** , // .

• ** returns exponentiation .
• // returns quotient after discarding fractional part .   
• % returns remainder . It is also called modulus operator .
• = is called assignment operator .

 Input :  
 >>>print(5+2) #Adding  
 >>>print(5-2) #substraction  
 >>>print(5*3) #multiplication  
 >>>print(5/3) #division  
 >>>print(5**3)  
 >>>print(5//3)  
 >>>print(5%3) 

 Output :  
 >>>7  
 >>>3  
 >>>15  
 >>>1.6666666666666667  
 >>>125  
 >>>1  
 >>>2  

• Compound assignment Operator

       +=  ,  -=  , *=  ,  //=  ,  /=  , **=   

1.  a += 3 means a= a+3
2. a **=3 means a=a**3

Python Conversion :

         We can easily convert one data type to another data type in python . Python provides very useful tool to do this operation like integer to float , integer to string , float to integer and vice-versa .

• int(float) : Convert float number to integer .
• float(int) : Integer to float

 Input :  
 >>>print(int(5.6)) # float to integer  
 >>>print(float(5)) #integer to float  
 >>>print(int('2')) #from numeric string to integer  
 >>>print(int('100',2)) #convert from binary to decimal int  
 >>>print(int('341',8)) #convert from octal to decimal int  

 Output :  
 >>>5  
 >>>5.0  
 >>>2  
 >>>4  
 >>>225
