Learning python - 2nd day (Noon)

I have completed this tutorial: Python Tutorial 5

I learnt now is about variables and some String modifier functions.

The first thing I learnt is I can store a value or a string in a variable name just like java and C++.

The difference is unlike other languages, there is no need of writing the variable type before specifying. Storing data in a variable is as simple as:

myNumber=8

Well I also learnt that I can modify a String variable in several ways.

For example: 

text='Shadow'

Way 1:

Input: text[0]

Output: S

Input: text[-1]

Output: w

Well so 0,1,2,3,4,5 is the character number... Let me define it much easy way:

  S  h  a  d  o  w

  0  1  2  3  4  5

-6 -5 -4 -3 -2 -1

Just like this.

Way 2: I can extract certain part from String

Input: text[0:3]

Output: Sha

Meaning like 012 characters from String

If I put null value the character indexes will be count till end.

Like:

Input: text[2:]

Output: adow

Or like 2345

Another special function I learnt is character counting from a String

Input: len(text)

Output: 6
