You can use F5 / F6, F7 and F8 to step through your coding. Debugging Key bindings Command Description F5 Goes to the next step in your program. If the next step is a method / function this command will jump into the associated code. F6 F6 will step over the call, e.g. It will call a method / function without entering the associated code.
F7 F7 will go to the caller of the method/ function. So this will leave the current code and go to the calling code. F8 Use F8 to go to the next breakpoint. If no further breakpoint is encountered then the program will normally run. Python allows the following String operations. String Operations Operations Description len(s) Returns the length of string s si Gets the element on position i in String s, position start with zero s-i Get the i-tes Sign of the string from behind the string, e.g.1 returns the last element in the string 'abcdefg'0:4 Gets the first 4 elements (abcd) 'abcdefg'4: Gets the elements after the first 4 elements (abcd) a+ b + c Concatenates the int varibles a, b,c, e.g.
If a=1, b=2, c=3 then the result is 123. S.lower Result will be s in lower cases s.upper Result will be s in upper cases s.startswith(t) True, if s startsWith t s.rstrip Removes the end of line sign from the string.
I'm a newbie trying to learn Cython. My operating system is Windows 7 and I'm using Eclipse PyDev as my IDE for Python development.
This article describes how to set up Eclipse for Django development on Windows. The software used is as follows:.
Python 3.4. Django 1.7.1. PyDev 3.8.0. Eclipse Luna JEE 64-bit Windows Edition. Windows 7 To set up Eclipse for Django on Windows, use the following steps:. Install Python. Download and install Python from here:.
Modify Your Path. Modify your path to include the location of Python as well as it’s Scripts and Tools Scripts directories.
![]()
For example, if python was installed to C: Python34, your path should contain the directories shown below: Path=.;C: Python34;C: Python34 Scripts;C: Python34 Tools Scripts. Set Up a Python Virtual Environment. Python 3.4 comes with pyvenv that can be used to set up a virtual environment, which creates a separate Python environment, so that you can modify it without affecting the system Python environment. For more information, see;. Use the following command: pyvenv directoryname For example:. Activate the Virtual Environment. Go to the virtual environment’s Scripts directory and execute the activate command.
This will prepend the path for the virtual environment to your path, so that the virtual environment’s Python commands will be used. Here is an example:. Install Django. Use pip (a package management too that is included with Python 3.4) to install django.
In your Python virtual environment directory, with the virtual environment activated, execute the following command: pip install django For example:. Install Eclipse. Download Eclipse from here:. I downloaded the JEE version of Eclipse, because it supports web apps, and I also develop in Java. Other versions could be used.
To install, unzip the downloaded file to a directory of your choice. Install PyDev. Install the PyDev plug-in for Eclipse, which supports Python and Django development. In Eclipse:. Select Help → Install New Software.
From the menu bar. In the Install dialog that should come up, enter the text below for the “Work with” field and then click on the Next button. An Install Details dialog should come up that lists PyDev Eclipse as the item to be installed. Click on the Next button.
A Review Licenses dialog should come up. Accept the terms of the license and click on the Finish button. A dialog should come up asking you if you trust the PyDev certificates. Select the certificate and click on the OK button.
You will need to restart Eclipse after the PyDev install, and a dialog should come up asking you if you want to do that. Click on the Yes button. Create a Django Project.
After restarting Eclipse with a new workspace specified:. Select File → New → Other from the menu bar.
In the Select a wizard dialog that should come up, select PyDev → PyDev Django Project and click on the Next button:. In the PyDev Django Project dialog that should come up:. Enter a project name, for example: mysite. Select the closest Grammar Version to 3.4 (3.0 was the closest available with the version of PyDev used).
Click on the Please configure an interpreter before proceeding. In the Configure interpreter dialog that should come up, click on the Manual Config button. In the Preferences dialog that should come up, click on the New button in the Python Interpreters section of the dialog.
In the Select interpreter dialog that should come up, enter an interpreter name, and select the Python executable in the virtual environment that you created, and click on the OK button. For example:. A dialog should come up where you select the directories to add to the SYSTEM pythonpath/.
Click the OK button. You should come back to the Preferences dialog.
Use drag and drop to reorganize the library directories, so that the virtual environment directories are listed before the system directories. Your preferences dialog should look something like what is shown below. When done, click on the OK button. You should now come back to the Python Django Project dialog.
For the interpreter, select the one that you just created and then click on the Next button. A Reference page dialog should come up. Just click on the Next button.
A Django Settings dialog should come up. Sqlite should be the default database system specified, so to use sqlite, just click on the Finish button. If you want to use another database system, enter the appropriate information in this dialog and then click on the Finish button. A dialog should come up asking if you want to use the PyDev perspective. Click on the Yes button. Run the Django Project. In Eclipse, click on the Run button:.
A Run As dialog should come up. Select PyDev: Django and click on the OK button. You should see the following in your Console view:. Check your site by accessing.
You should see something like the following.
Python 3 as interpreter in Eclipse The PyDev plugin adds support for working with Python files to Eclipse. However, it is only auto-configured to work with a Python 2.x interpreter. Furthermore, Ubuntu installs Python 2.x by default and needs some manual work to work with Python 3.x. To use Python 3.x for your Python files in Eclipse:.
First install Python 3.x: $ sudo apt install python3. This installs the Python 3.x interpreter as /usr/bin/python3. We will use this in Eclipse.
In Eclipse, open Preferences - PyDev - Interpreters - Python Interpreter. Click Add and add /usr/bin/python3. The Libraries and other settings will be auto-discovered by PyDev. That is it! When you create a new Python project, in its dialog remember to pick Grammar version as 3.0 and the Interpreter as Python3. Tried with: Python 3.4.0, PyDev 3.9.0, Eclipse Luna 4.4.1 and Ubuntu 14.04.

Due to its power, simplicity, and complete object model, Python has become the scripting language of choice for many large organizations, including Google, Yahoo, and IBM. In Python 3 Essential Training, Bill Weinman demonstrates how to use Python 3 to create well-designed scripts and maintain existing projects. This course covers the basics of the language syntax and usage, as well as advanced features such as objects, generators, and exceptions. Example projects include a normalized database interface and a complete working CRUD application. Exercise files accompany the course.

In here we have the Python download page. And I've already downloaded the Python 3.1.2 Windows X86 MSI installer. That's the 32 bit version. And even if you're on a 64 bit capable machine, I'm probably going to recommend that you run the 32 bit version, and we'll get to why in a moment.
First we're going to look at the eclipse download page. Eclipse is an integrated development environment, an IDE. It's written in Java, and it's designed for Java, but it works well with a number of languages. You'll notice that there's all kinds of different packages for different types of development work here on the Eclipse download page. Now, if you're doing development in Eclipse and you're using a different version of Eclipse, PHP version or the C version, or the Java version, that's fine. You can go ahead and use that and install the PyDev development environment inside of that and that will work just fine.
