You have stumbled over the general problem with encodings:

Writing a program using python to create

You should see a result something like this: You might see other suffixes than those shown here. For example, if you have debugging enabled, you'll see a -debug suffix. It's possible to set up the script so that it can be run by name without invoking Python explicitly. Under Unix, add an initial!

This tells the system what program should execute the script. Many Unix accounts are set up not to search the current directory when looking for commands. Instead, you can set up a filename association so that. Instead of using chmod to make the script executable, open the Folder Options item in the Control Panel and select its File Types tab.

File Types enables you to set up an association for files that end with.

Reading and Writing Files in Python Open takes 2 arguments, the file that we want to open and a string that represents the kinds of permission or operation we want to do on the file Here we used "w" letter in our argument, which indicates write and the plus sign that means it will create a file if it does not exist in library The available option beside "w" are "r" for read and "a" for append and plus sign means if it is not there then create it Step 2 for i in range

Getting Started with Python A print statement can output multiple things at once, each item separated by a comma.

Then you can invoke the script by name: For example, it doesn't catch exceptions or indicate what went wrong if an error occurs, and it doesn't allow for the possibility that the statement it runs might not return any results. This section shows how to address these issues using a more elaborate script, animal.

Error Handling After importing the requisite modules, animal. To allow for the possibility of connection failure for example, so that you can display the reason for the failureit's necessary to catch exceptions.

To handle exceptions in Python, put your code in a try statement and include an except clause that contains the error-handling code. The resulting connection sequence looks like this: Error in this example to obtain the database-specific error information that MySQLdb can provide, as well as a variable e in which to store the information.

If an exception occurs, MySQLdb makes this information available in e. The except clause shown in the example prints both values and exits. The complete text of animal. Methods for Issuing Statements The next section of animal.

Remember that it will be placed in a try statement; errors will trigger exceptions that are caught and handled in the corresponding except clause, which allows the main flow of the code to read more smoothly. The statements perform the following actions: Drop the animal table if it already exists, to begin with a clean slate.

Create the animal table. Insert some data into the table and report the number of rows added.3. Using Python on Windows¶. This document aims to give an overview of Windows-specific behaviour you should know about when using Python on Microsoft Windows.

Writing The Code. I like to write my python scripts using the IDLE IDE because it comes packaged with the Raspbian distribution, it's free, and it makes writing and debugging code a bit simpler than when using Python command line or a text editor.
