*Hello and welcome to this tutorial on Basic Python using Python.
This tutorial formally introduces Python as a language . Through this tutorial we will be able to understand Basic Data types like number , Boolean and strings .Some basic operators , simple input/output and basic conditional flow .
In numbers Python supports three kinds of data types ,
floats,integers and complex numbers
An integer can be defined as follows :
a=13
This make a an integer variable with value 13 .
You can also type 9 around 20 times
a=99999999999999999999999 . as you can see Python does not have a limit on how long an integer has to be . Isn't that great .
Now will try a float.
let's type
p=3.141592 if you type out p now you will notice that it is not absolutely equal to p you typed in . The reason for that is how a computer saves decimal values .
Apart from integer and float, Python has an in-built support for complex numbers. Now we try to assign a complex value to a variable .
Type:
c = 3+4j
As you can see ,the notation for complex numbers is similar to the one used in electric engineering.
We will now try some operations on complex numbers . First we will try to get the absolute value of the complex number . For this we will use the abs built in function . For this do :
abs in parenthesis c .
Do get the imaginary part of c you can do :
c.imag
and similarly for real part do :
c.real
Python also has Boolean as a built-in type .
Try it out just type ..
t=True , note that T in true is capitalized .
