PyCharm an integrated development environment.

The development team comes with this integrated development environment (I.D.E.) named: PyCharm.
They tell us about this integrated development environment:
Python IDE with a complete set of tools for productive development with Python programming language. In addition, the IDE provides high-class capabilities for professional Web development with Django framework and Google App Engine. It has powerful coding assistance, navigation, a lot of refactoring features, tight integration with various Version Control Systems, Unit testing, powerful all-singing all-dancing Debugger, and entire customization. PyCharm is developer driven IDE. It was developed with the aim of providing you almost everything you need for your comfortable and productive development!
I usually use it and from my point of view, it is very quick to learn and use.
Also, some features like Servers come is supported in the Professional edition only.
The menu is easy to remember and the project settings come automatically.
You can start from the main menu: File - New Project...
A little more complicated element is putting new scripts into the project File - New.
The python file can be added and the type of python version can by editing the configuration menu: Run - Edit Configurations...
The editor comes with unindent and convert fro tabs and spaces.
This I.D.E. comes with common version control operations integrations, like:

• CVS Reference
• Git Reference
• Mercurial Reference
• Perforce Reference
• Subversion Reference

Also, some official tutorials can also be found on the official website.
You can read more about this software here.

The JetBrainsTV is the official youtube channel of this I.D.E.

Python tutor - web tool for python programming.

The website comes with this intro about this web tool.
Python Tutor, created by Philip Guo, helps people overcome a fundamental barrier to learning programming: understanding what happens as the computer runs each line of source code.
Using this tool, you can write Python, Java, JavaScript, TypeScript, Ruby, C, and C++ code in your web browser and visualize what the computer is doing step-by-step as it runs your code.
Over 3.5 million people in over 180 countries have used Python Tutor to visualize over 30 million pieces of code, often as a supplement to textbooks, lectures, and online tutorials.
I tested and worked very well.
You can use python programming language 2.7 and 3.6 versions.
No need to import python modules, you will get an error.
Just programming on the fly to test and see the result.
The website comes with some example to see how to deal with this tool.
Let's see some examples:

example with factorial :

# dumb recursive factorial
def fact(n):
    if (n <= 1):
        return 1
    else:
        return n * fact(n - 1)

print(fact(6))

example with for - else:

# find primes using a for-else construct
for n in range(2, 10):
    x_range = range(2, n)
    for x in x_range:
        if n % x == 0:
            break
    else:
        # loop fell through without finding a factor
        print(n)

example with inputs:

prefix = "Hello "

n1 = raw_input("Enter your name")

n2 = raw_input("Enter another name")

res = prefix + n1 + " and " + n2
print(res)

Run your script just press: Visualize Execution or Live Programming Mode buttons and the will run step by step with:
First, Back, Forward and Last.
One good feature of this tool - with a single line of JavaScript code, you can embed a Python Tutor visualization within any webpage.
Another good feature is COLLABORATE to learn together - this allow us to give and get direction with real-time python programming.
Can be a good tool for python chat users.
Let's show you a screenshot to see how this tool working with python scripting.

The speech python module.

About this python module can be read here.
It's a little undocumented and I have not found tutorials about this python module but I tested with a simple example.
I'm sure he can do more than I tried with my example.
First, the install of this python module:

C:\Python27\Scripts>pip install speech
Collecting speech
  Downloading speech-0.5.2.tar.gz
Installing collected packages: speech
  Running setup.py install for speech ... done
Successfully installed speech-0.5.2

Let's see more about this python module:

Help on module speech:

NAME
    speech - speech recognition and voice synthesis module.

FILE
    c:\python27\lib\site-packages\speech.py

DESCRIPTION
    Please let me know if you like or use this module -- it would make my day!

    speech.py: Copyright 2008 Michael Gundlach  (gundlach at gmail)
    License: Apache 2.0 (http://www.apache.org/licenses/LICENSE-2.0)

    For this module to work, you'll need pywin32 (http://tinyurl.com/5ezco9
    for Python 2.5 or http://tinyurl.com/5uzpox for Python 2.4) and
    the Microsoft Speech kit (http://tinyurl.com/zflb).


    Classes:
        Listener: represents a command to execute when phrases are heard.

    Functions:
        say(phrase): Say the given phrase out loud.
        input(prompt, phraselist): Block until input heard, then return text.
        stoplistening(): Like calling stoplistening() on all Listeners.
        islistening(): True if any Listener is listening.
        listenforanything(callback): Run a callback when any text is heard.
        listenfor(phraselist, callback): Run a callback when certain text is heard.

Let's make a simple example with one script that tells us something:

>>> speech.say('Hello Catalin George')

The result of this line of code will be heard into your audio device like Hello Catalin George.

Python Qt4 - part 006.

Today I will deal with QFileDialog widget.
You can read the more about this widget here.
This allows us to open a dialog to load a resource - a file.
The example comes with the base PyQt4 application window with a my_example dialog from fileDialogSample python class.
Into this python class, I have some variable for the file: file_name, data and my_file_open.
The my_text_edit for text area and my_button to open the QFileDialog.
Also, the vbox variable to put all on QVBoxLayout from the application.
Let's see the example:

import sys
from PyQt4 import QtGui
from PyQt4 import QtCore

class fileDialogSample(QtGui.QWidget):
    def __init__(self):
        QtGui.QWidget.__init__(self)

        #make text area and button
        self.my_text_edit = QtGui.QTextEdit()
        self.my_button = QtGui.QPushButton('Select File', self)

        #open the showDialog
        self.my_button.clicked.connect(self.showDialog)

        #put all into application area
        vbox = QtGui.QVBoxLayout()
        vbox.addWidget(self.my_text_edit)
        vbox.addWidget(self.my_button)
        self.setLayout(vbox)

        #set title and geometry of application
        self.setWindowTitle('File Dialog example')
        self.setGeometry(50, 50, 300, 300)

    #make a function with seeting for my QFileDialog
    def showDialog(self):
        file_name = QtGui.QFileDialog.getOpenFileName(self, 'Open file', 'C://')
        my_file_open = open(file_name)
        data = my_file_open.read()
        self.my_text_edit.setText(data)
        my_file_open.close()

#run the application 
app = QtGui.QApplication(sys.argv)
my_dialog = fileDialogSample()
my_dialog.show()
sys.exit(app.exec_())

Now, just press the Select File button, take a text file and open it.

Python Qt4 - part 005.

Another example with PyQt4 that allow seeing images over the internet.
Here's another simple example with PyQt4 that allows you to view images on the internet.
You can use any image on the internet to display with this python script.
This example is done in two steps:

• take a single image from the internet - httplib python module;
• displaying - PyQt4 python module

from PyQt4 import QtGui
import sys
import httplib

def getTempPNG():
   conn = httplib.HTTPConnection("www.meteoromania.ro")
   conn.request("GET", "/sateliti/img/id814/id814_2017070718.png")
   return conn.getresponse().read()

def main():
   app = QtGui.QApplication(sys.argv)
   png = getTempPNG()
   pixmap = QtGui.QPixmap()
   pixmap.loadFromData(png)
   label = QtGui.QLabel()
   label.setPixmap(pixmap)
   label.setWindowTitle('METEOSAT-10 Thermal Infrared Channel 10.8 micrometers Glowing temperature')
   label.show()
   app.exec_()

if __name__ == '__main__':
   main()

The result can be seen in this screenshot:
