These options are variable, textvariable, onvalue, offvalue, and value.

Its primary purpose is to act as a spacer or container for complex window layouts. Font sizes with positive numbers are measured in points; sizes with negative numbers are measured in pixels. Would you like to open it in a new window? The file worked well with linux, and I should like it does the same with windows. The standard library is included as pre-compiled and optimized. It is designed for making plan before developing a product or service.
An example variable could look like this assuming the first two entries already existed : New in version 3. This means that when you double-click on one of these files from Windows explorer the launcher will be used, and therefore you can use the same facilities described above to have the script specify the version which should be used. Import statements other than to site are not permitted, and arbitrary code cannot be specified. The output directory may be changed from.

Shebang Lines If the first line of a script file starts with! Drove me crazy for a while. From file associations The launcher should have been associated with Python files i. Third-party packages should be installed by the application installer alongside the embedded distribution.

The long term goal is to use this as the basis for other instruments like a tachometer, rms voltmeter, wattmeter, tachometer, lock in amplifier, capacitance and inductance meters, etc. To completely override , create a.

This is for backward compatibility and for compatibility with Unix, where the command python typically refers to Python 2.

The return value of these calls is a dictionary whose key is the name of the option as a string for example, 'relief' and whose values are 5-tuples. The source tree contains a build solution and project files for Microsoft Visual Studio 2015, which is the compiler used to build the official Python releases.
