You can run one of the files created in the examples by double-clicking it. The Python script for this section, Listing 1, illustrates a very basic approach to retrieving historical prices and volumes for the nvda ticker.

This ticker represents the Nvidia Corporation, which is a manufacturer of computer processors for such application areas as gaming, professional visualization, datacenters, and artificial intelligence. Reading the comments in Python scripts throughout this article will help you understand the function of code or other special issues about the code. The hash sign in a Python script denotes a comment similarly to the way that T-SQL denotes a comment with a double-dash —.

This method is used to import data from a handful of Internet sources, so it is very useful for extracting stock market data. Commentary on the other aspects of the script are reserved for the next section so that this section can highlight primarily the DataReader method for collecting historical price and volume data. A dataframe object is a construction that is generally like a SQL Server table for storing data in a tabular format. In this script, constants are used to specify start and end dates September 1, and December 31, , respectively.

Data are returned for stock market exchange trading days only. Therefore, weekends and a select set of holidays on which the markets are closed do not have historical prices associated with their dates. By using constants for specifying start and end dates, the code sets fixed limits for the date range for collecting data. The script gets data for trading days from the start date through the end date. If the end date is more recent than the current date, then the last row of data will be for the current date.

If the script is run on multiple days in December , before the end of the month, then its output can reflect fresh data for each successive distinct day on which the script runs.

However, once December concludes, the script always returns the same data for September through December unless, of course, there is a data revision, such as for a stock split. You can think of the output from the script as a snapshot of the historical data in Yahoo Finance. The argument inside the method specifies the name for the new file. NOTE: You can run the script by double-clicking it. Figure 1 shows Yahoo Finance historical data for the nvda ticker for the first three trading days of September from the Yahoo Finance user interface that was set to display data from September 1 through 6 in The Python script accesses a programmatic interface instead of the user interface shown in Figure 1.

By comparing the two images, you can confirm that the Python script can generate the same results as the Yahoo Finance user interface. The Python script in this section, Listing 2, adds a couple of enhancements to the original script. Instead of using a fixed date range from the beginning of September through the end of December in , this script allows the collection of historical prices and volumes over a dynamic date range.

Additionally, this new script also includes code for designating a specific folder for saving the csv file instead of accepting the default option which saves it in the same folder as the script file. This section will also drill down into selected features of Python scripting features not covered in the preceding section.

The script starts with two import statements. An import statement allows a Python script to reference code from an external or built-in library. The remaining code within the script to refers to methods in the library by web. The second import statement in the script references the built-in datetime library.

Python has multiple code containers with some overlap between types of containers. For example, a library and a module are sometimes used interchangeably as code containers. Therefore, you can find documentation referring to the built-in datetime library as well as the datetime module. The datetime library and datetime module refer to the same body of internal Python code. The datetime internal library enables dynamic date values for the start and end date arguments for the DataReader method.

Each user attribute in your organization's Percipio site has a column. Enter the values you want to associate to a user. String attribute values retain their case "Location" is considered a different value than "location" or "LOCation". List attribute values use the first instance of a value for all subsequent values "Location" is the same as "location" and "LOCation".

The fields below do not appear when you download a batch template. You can manually add a column to the batch template anywhere after the loginName and externalUserID columns, if needed. If you do not want to require a user to change her password, the following values are acceptable:. If your users are accessing Percipio directly with their Percipio login name, and you are sending a welcome email, we recommend having users reset their password.

If you specify a password and send a welcome email without requiring users to reset their password, the user will not know their password for subsequent logins. Specify a new password for the user. If you leave the field blank, the user retains their existing password. Percipio does not notify the user of the password change. If you are resetting passwords for multiple users and using the same password for all, for security reasons, add the mustResetPassword field to your batch file to force users to create their own password upon sign-in.
