PyDev - the Python IDE to Use

Image via Wikipedia

If you have been following this blog, you know that I have been evaluating which Integrated Development Environment (IDE) for Python is best for me. My co-worker found PyDev which runs in the Eclipse environment. Upon trying it out and both of us evaluating, PyDev is going to be what we are going to use to convert an AML project to Python. We chose this IDE for the following reasons:

1. IDE is based on Java - this means that Eclipse run on almost any platform: Windows - Mac - Linux - Unix
2. Free - Costs nothing to install or use
3. Python works in Eclipse and IronPython (a .Net Framework platform) and Jython (a Completely Java platform).
4. Can be pointed to any version of Platform that we need including Python 2.5 used by ArcGIS.
5. Good textual editor
6. Excellent debugging tools
7. Not too difficult to install.

I just learned how to install it today in Windows. It must be installed and then configured correctly.
0. Get the Python libraries and interpreter from
1. Make sure you have the latest JVM (Java Virtual Machine) installed on your computer. If you don't have it, get it free from http://www.java.com/en/download/index.jsp
2. Download Eclipse by downloading eclipse-jee-galileo-win32.zip
3. Unzip it into any folder on your c:\ drive that you want.
4. Download PyDev from http://sourceforge.net/projects/pydev/files/pydev/Pydev%201.5.0/org.python.pydev.feature-1.5.0.1251989166.zip/download
5. org.python.pydev.feature-1.5.0.1251989166.zip is a zip file that contains all you need to complete the installation. You just unzip the files in the Features folder and put them in the Features folder installed by the Eclipse zip file and you do the same with the files in the plugins folder.
6. Start Eclipse by double clicking on Eclipse.exe Choose the location for your worksapce



7. Start at the top menu and select Windows - > Preferences



8. Hit the "New"button and select the python executable for the version you want to use. For me I picked the 2.5 version of python and select all the libraries. Then hit "Apply" then "OK"



9. Select File -> New -> PyDev Project. Enter the required information. Make sure that the "Grammar Version" matches the Interpreter you chose for the project. It is 2.5 In my Case.

10 Add source code to Project. If you are writing a new module, right-click on project name and choose New. Select the type of file you want to add and to what folder.



11. Alternatively, you can import a file into the project from omne folder to another folder. Right-click on project name and choose Import.



12. Now that your project has code to run, Right click on project name -> Properties and select Run/Debug settings on the left.



13. Select the new button and select "Python Run" and then name your configuration whatever you want. On the main tab, browse for the name of the project to run asnd the name of main module



14. On the Arguments tab is where you enter your input arguments of the scripts and for the interpreter



In this example I'm testing a script that take a string of temperatures converts them from Fahrenheit to Celsius and then Celsius to Fahrenheit

15 Hit the apply button
16. The select Run -> Run to run the script!

Python Tutorial

Image via Wikipedia

I've been learning Python and here is what I have learned so far:

1. Python is a scripted language

2. In Python, indentation matters because it's how logic blocks are grouped together

3. Python is not strongly typed like C++, C#, and Java

4. Python has the following data types - dynamic

a. Lists - dynamic array can be appended, sorted, and all kinds of goodies; defined by []

b. Tuples - array that can't be changed

c. Dictionaries - ie {'key': 'value', 'a' : 'b'}, d['k'] = 'v‘

d. integer

e. float

f. string

g. Special statements

i pass,del, raise, assert, exec
ii global
iii break
iv continue
v try

5. For loops

for item in sequence:

Statements

else:

statements

– Example:

for item in (1,3,5,7,9,15,2003):

print item

for item in xrange (1, 50):

sum += item

6. While loops
While ... [else]

while a == b:

work ()

else:

finalize ()

7. If statements
If ... [elif ... else]

if a == c:

print “a equals c”

else:

print “a and c are different”

8. Functions and Procedures
def name(arg1, arg2, ...):
"""documentation""" # optional doc string
statements

return # from procedure
return expression # from function

9. Exception
def foo(x):
return 1/x

def bar(x):
try:
print foo(x)
except ZeroDivisionError, message:
print "Can’t divide by zero:", message

bar(0)

10 File Input/output

f = open(filename[, mode[, buffersize])
mode can be "r", "w", "a" (like C stdio); default "r"
append "b" for text translation mode
append "+" for read/write open
buffersize: 0=unbuffered; 1=line-buffered; buffered

methods:
read([nbytes]), readline(), readlines()
write(string), writelines(list)
seek(pos[, how]), tell()
flush(), close()
fileno()

Creating Free Flash Websites

I have heard about a service that allows you to build flash websites and widgets for free. You just go to Wix.com and it allows you to pull almost any popular flash trick you have seen using drag and drop technique. It makes it really simple! Here is an example:

Adding Polls to Web Site/Blog

I have found 2 ways to put polls in your blogger post. Most tools allow you to put polls into the side bar of your site, but if you want to put it in your post you have to go through a little work.

1. Method One -
I like this method just fine. You just use the widget for installing a poll into the blog and then copy and past the HTML for generating into the post that you want.

2. Use a service like PollDaddy. You get a free account, design the poll, and then get the code to make the poll as a flash object. Then you can paste it where you want it. This my preferred method!

Tweetstream

Here is a cool tool that allows users to add near real-time twitter stream to any website or blog. You can get it at TweetSteam.

I've just come across another Twitter tool designed to allow users to share files with one another. This one is pretty cool. Just login using your twitter account, browse for the file on your computer you want to send, and then send it. The homepage is at Tweetafile.

Addendum to Summarizing Blog Posts

As I mentioned in the previous post there is a way to automatically summarize your blog posts with thumbnails. However I found the problem that when you go to the full post, you can't return back to the listing without hitting the "back" button on your browser. So I added a code to add a link to allow the user to return to the main pages. Add the following to the next line after the the steps proscribed.

<p><a href="[URL]">Return to main page</a></p>

Summarizing Posts on a Landing Page

I have looked at some ways of trying to change my blog to make it more user-friendly. One suggestion made by friend Mariano suggested that I add the function of summarizing my blog posts on the main page and giving the reader the option of reading further. The idea is to make the blogs load faster and make it more easier to use.

Mariano suggested a method where each post is summarized in the HTML using small changes in the blog's template and in the post itself. This method is great because it give you so much control over what the post looks like when the blog loads. The problem is that in order to take advantage all older posts will have to be augmented but every new post will have the structure in place and I am too lazy to add the HTML to the older posts because I have blogs containing more than 500 posts. Here is the code on how to make it happen from Mariano himself and you can visit Mariano's blog, Atheism is Dead, to see it in action.



I have found another alternate method to do something similar. I like this method a little better because it automatically summarizes the posts and puts a thumbnail of the first image in the post in the summary. In order to pull it off, you just need to follow the steps in the following website: Automatic Post Summaries for Blogger with Thumbnails. You have control over how many words are in the summary as well as quite a few other things.
