Python : String functions



Hi all , I will show how to use some string related function and operations on list datastructure in python

String function

Length of string 

len(string)  - > This will bring the length of the string passed to it.

Check if a character in string is upper case of lower case

string[i].isupper() - > This is for checking upper case
sttring[i].islower() - > this is for checking lower case

Convert a character to upper case or lower case

a = string[i].upper() - > This is for converting a character to upper case
a = string[i].lower() - > This is for converting a character to lower case

Please note here i means the index of the character in the string.

Split a line of words 

k = string.split(" ")

Here the string is split and words a assigned to a list. The delimited used is " "

List operations

Initialize as list

K = []

This will initialize a list

Add or append a value to list

k.append("a") - > This will add character a to list K.

Mount an iso image in ubuntu using no GUI

We can easily mount an iso image file in our system to a directory in linux.We need not require an GUI application to do this.It is easy to do from the terminal itself. We use the mount command for that. The steps are as follows  1. Open the terminal in ubuntu (Shortcut press ctrl+Alt+t) 2. Create a directory to mount the iso image              $sudo mkdir /media/myimage 3. Then type the following command     $sudo modprobe loop 4.After that go to the location of the iso image file and type     $sudo mount /media/myimage -t iso9660 -0 loop     The iso file is mounted to the specified directory To unmount it give the command   sudo unmount /media/myimage That all.Cool isn't! sudo modprobe loop will loads the module for loopback file system iso9660 is the file system used by CD-ROM -t specify the file system type -o loop additional option used by a loopback filesystem

UNIX : How to get record count from zipped file

Sometimes we may need to get records count from file . For that we can use wc -l , command with file name. In some situation the file will be in compressed format . wc -l will not directly work with zipped files . In this case we can do zcat the file and pipe the word count command with it. Example : Let say we have a file cricketData.dat.gz To get word count from the file use : zcat cricketData.dat.gz | wc -l This will give the record count.
