Hi Friends,

Here I am again with you guys after a long time . Sorry for the delay, but i was caught up in office work for a long time and was extremely busy.

So, let us delve further into python, without waiting any further .

Think about arrays (feisty little boxes i call them) . Lists are very much like them . They can contain any and all types of variables and as many as you wish.

We will declare a list first . Let's call it Klist .

Klist = [] ; //declaring a list

//Let's build the list

Klist.append(K);

Klist.append(B);

Klist.append(C);

So the list now contains 3 elements A,B,C .

Lets print the elements inside the list now :

for i in Klist :

print i // Prints K, B C

Now beware . This is very important .

This list contains 3 elements . So if you try to print an index, for which there is no element in the list .

Hence,

print Klist[12] ; // This generates an error as, for the index 12 , there is no element in the list .

All arithmetic operations are supported in python .

Addition, Subtraction , multiplication you name it , everything's there .

To return remainder from a division you can use the modulo operator (%) .

To make a squared relationship , you can use double * operators.

a = 7 ** 2 ; // that's actually 49

To concatenate strings you can add them up .

kunalBhowmick = "Kunal" + "Bhowmick" ;

To concatenate a string multiple times :

Kstring = kunalBhowmick * 10 ;

That makes the list Kstring contain 10 repetitive sequences of the string "kunalBhowmick " .

To join two lists you can use addition (+) operator .

New lists can be made with a repeating sequence using the multiplication operator (*) .

For example:

print Klist * 3 ;

This prints the elements of the list Klist 3 times .

That's it friends for today . Next we will go through loops and conditions .

**LISTS :**Think about arrays (feisty little boxes i call them) . Lists are very much like them . They can contain any and all types of variables and as many as you wish.

**Consider this scenario :**We will declare a list first . Let's call it Klist .

Klist = [] ; //declaring a list

//Let's build the list

Klist.append(K);

Klist.append(B);

Klist.append(C);

**OPERATORS :**All arithmetic operations are supported in python .
