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                                                           ...

Hello Guys ,Today i am uploading  questions related to our post i hope that you learnt something new concept from this post. also Comment your answer below my post 1.Which of these is not a variable?    a.    abc    b.    x_y    c.    123    d.   _a12 2.Which of the following is an invalid statement?    a.    abc=1    b.    a   b   c= 1 2  3    c.    a,b,c  =1000,2,3    d.    a_b_c=1,000,000

Data Types in Python:                              From the name it refers that " Data Types "  Here Data Means "information" and types  means "Kinds" we can say that Data Types means Kinds of Data. Why data?           Actually our main Motto of making Program is to processing some data.Ex-Lets us we have to stored some data related to some students  (like marks) and also we have to perform some operation on that data . so that it can easily perform some operation .Like we have to find the average of the marks,percentage of the marks etc. On what factors data is categorized? 1.Memory 2.Operation 3.Internal Representation. But In python We don't have to declare the types of the data while using. like C,C++,Java. ex- a=6 Here,  "="   Don't read it as equal to ,it a assignment operator or simply assign.   ...

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.

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)
