Variable Naming Rules

-

  • Variable name can be a combination of alphabet,number and underscore( _ ).
  • Variable name can't start with digits.
  • Variable names are case-Sensitive language.(means that ex- pramod and PRAMOD are treated as differently.
  • Keywords can't be used as Variable Name.
Dynamically Typed Language

  • Other language like c ,c++,java is statically typed language.but python is a dynamically typed language.(Let us understand by an example
  • x=5 (int type)
  • After some line of code we also write x=6.4( float type)
  • After some code we can change the the value x="Pramod"

 Important Points
  •        Not only the value of a variable, we can also  change the data type of a variable .
             ex-x=5
                  x=3.5
              Now,Here at first we assign the int type value in x.After some we assign the float value in the same variable x in the same program.

We have already Learnt on the previous post that there is 14 Built in data types in python. Today's Agenda type() int() float() ord() complex() Now ,                   If you have to make a variable x i.e.x=5 then On run -time,the interpreter decides its type after considering the content of that variable . we can also verify it by using a function called type() in IDLE. Note:  IDLE is a short form of Integrated Development and learning Environment. Type Conversion:                                   At first ,we understand that why do we type conversion in python by an example. let us consider that a variable x=6                                                           ...

What's Comments?????? ? Comments in your python Scripts are statements that you want to ignore by the interpreter. Why Comments?? To make the code more understandable. Types of comments Two types                  -To indicate what a section of code perform. (usually for programmers)                  -Multi-line comment serve as documentation for others. Ways to write comments 1.Single line comments are created simply by starting a line with hash(#)character. 2 .Multi line comments are created by adding delimiter("""   """) or('''    ''') on each    end of the comment .      Ex-Comments shown below in IDLE(as a editor in python)

KEYWORDS in  PYTHON Predefined or Reserved words are called keywords.         Note :They can't be used as variable name as their meaning is already reserved. There are 33 Keywords in python 3. If you want to see the list of keywords in python Just go to IDLE       FILE->New->save as test.py code:     import keyword     print(keyword.kwlist)                               1.Three keywords True,False,None start with capital letter while other keyboard start with small letter. 2.In python ,                     do while loop,switch expression is not available like C,C++ etc. 3.In python,                    if  else,while for,and or not is available as keyword.
