Python Script: Optimize mysql tables

Hello Friends,

Below is the script for optimizing database This will decrease the size of tables in most of the cases. I have used python 2.x for this:
-----------------------------------------------------------------------------------------------------------
import os
db = raw_input ( 'Enter the name of the table ')

cmd1 = 'mysql -u root -purpassword android -e "select (data_length+index_length)/power(1024,2) MB from information_schema.tables where table_schema=\'android\' and table_name=\'' + db + '\' ;"'


cmd2 = 'mysql -u root -purpassword android -e "create table ' + db +'_COPY like ' +db + '; " '


cmd3 = 'mysql -u root -purpassword android -e "alter table ' + db + '_COPY disable keys ; " '


cmd4 = 'mysql -u root -purpassword android -e "insert into '+db + '_COPY select * from ' + db + ' ; " '


cmd5 = 'mysql -u root -purpassword android -e "alter table ' +db+ '_COPY enable keys; " '


cmd6 = 'mysql -u root -purpassword android -e "RENAME TABLE ' +db+ ' TO ' +db+'_delete ; " '


cmd7 = 'mysql -u root -purpassword android -e "RENAME TABLE ' +db +'_COPY TO ' +db+ ' ; " '


print 'The size before optimization'
os.system(cmd1)
os.system(cmd2)
os.system(cmd3)
os.system(cmd4)
os.system(cmd5)
os.system(cmd6)
os.system(cmd7)

print 'The size after optimization'
os.system(cmd1)

---------------------------------------------------------------------------------------------

Notes:

1. Replace your password with urpassword
2. android is database name
3. 'db' is the variable where your tables name is stored.

Python: Rename all files in a folder with names as numbers in ascending order

Hi Friends,

This script will rename files as 1.zip, 2.zip, 3.xls etc for all files in same folder as scripts:

import os
x = 0
for filename in os.listdir(os.path.dirname(os.path.abspath(__file__))):
    ext = filename.split('.')
    extension = ext[1]
    os.rename(filename, str(x) + '.' + extension)
    x = x + 1

=====================================================================

Explanation:

1. extension = ext[1] collects the extension of file. If you skip this line, the files will be renamed without any extension.

2. Script should be in same folder as files. There should not be any folder in the folder.

Tunneling through putty: Accessing a internal website or service outside the network

Hello friends, there are many situation where you have to open a service or website that is neither in your network nor running with a public IP. The site or service is running properly inside the network, but you have to use it outside the network. Is it simple? Yes. 

First you need to download putty.exe. Go, download and then read further. 

All right, let us assume you are working on a local PC, lets say its IP is 192.168.1.50.  There is another website 192.168.3.33, which you cannot open on your local PC, as this is on different network. If you can access it directly, because of something you have already done, then no need to read further. Lets say you have another server, 192.168.3.110,  be it different or same as the website hosting server, but it must be on 192.168.3.x network. Then do as below figures:




You will use the port as per the website. In my experience, even if you use any different port, it will work.
Now, put IP of website in destination, port in source port and then add…

Python: Send mail with attachment ( Any file format)

So you want to send mail with any file as attachment. This script works with any type of attachment. I have given the example of .kml file, an unusual one. You can use pdf, docx etc.



import mimetypes
import email
import email.mime.application
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEImage import MIMEImage
import smtplib

# Create a text/plain message
msg = email.mime.Multipart.MIMEMultipart()
msg['Subject'] = 'Groove'
msg['From'] = 'mysender@gmail.com'
msg['To'] = 'receiver@gmail.com'

# The main body is just another attachment
body = email.mime.Text.MIMEText("""Hello, how are you? """)
msg.attach(body)

# KML attachment
filename='cache/20140210204804.kml'
fp=open(filename,'rb')
att = email.mime.application.MIMEApplication(fp.read(),_subtype="kml")
fp.close()
att.add_header('Content-Disposition','attachment',filename=filename)
