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.
