Assignment Operators in Python   Assignment operators : Assignment operators are used to assign the value to the variable. Operators Description Syntax = Is used to assign value to the variable. a = 5 += Add left operand to right operand and assign value to left operand. b += a -= Subtract right operand from left operand and assign value to left operand. b -= a *= Multiply left operands with right operands and assign value to left operand. b *= a /= Divide left operand by right operand and assign value to left operand. b /= a **= Calculate power of left operand to right operand and assign value to left operand. b **= a //= It perform floor division as it divide left operand by right operand , it return the value of quotient and a...

  Arithmetic Operators in Python Python programming has collection of operators to perform various operations.an operators is a symbols which operates on value or variables. Arithmetic Operator     : Arithmetic operators are the binary operators. Arithmetic operators are used to perform mathematical operations. Addition , Subtraction ,Multiplication ,Division are the basic operation performed by the arithmetic operators. Operator Name Syntax + Addition : Use to add two operands X + Y - Subtraction: Use to subtracts two operands. X – Y * Multiplication : Use to multiply two operands. X * Y / Division : Use to divide two operands. X / Y % Modulus : Use to returns the value of remainder after dividing two operands. X % Y ** Exponentiation (power) : Use for calculating...

    Python Data types Data types is the value which we want to store in variables .In which variable are store in different data types Python provide the type() function to Identify the type of variable .In Python there are some standard data types which are used to define storage method .In Python there is no need to define the type of variable in the statement of variable declaration .when the value is assigned to the variable , the interpreter set the data type of variable. There are five types of data types provide by Python        1. Number    2. String 3. List  4. Tuple          5. Dictionary Number :  Number are used to store numeric value .Number object is generated by Python when a number assigned to a variable. In Python there are four types of numeric data. integer (int) : signed integer such as 5,10,15,etc. long : used for high range value like 1234567890 Float : used for point number such as 1.21,3...

  Comments in python The comments are the statement in the code which are ignored by the python interpreter.  Comments are used to add additional information about the program and the statement to understand by the people. Comment can written anywhere in the program and it is good to write comments in code. The comments in python begin with the # (Hash) character.  Anything written in the # is considered as single line comment in a python.   # This is the comment in python. Types of comment : In python there are two types of comments . 1.Single-line comments. 2. Multi-line comments. Single-line comments : The single line comments start with the # character.it can write inline with code and also in an individual line. Example :  # the print() function use to print message on the screen or output device  print("Comment in the python")  output : Comment in python we see the one more example a=2 # value of a is integer b=2.5 # Value of b is float c= ...
