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 .
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);
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 .
OPERATORS :
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 .
