For instance, when we perform text pattern matching in Python, we create pattern objects, and when we perform network scripting, we use socket objects. These other kinds of objects are generally created by importing and using modules and have behavior all their own. As we’ll see in later ...
A GUI program for fast analysis of powder X-ray diffraction Images. It provides the capability of calibrating, creating masks, having pattern overlays and showing phase lines. Maintainer Clemens Prescher (clemens.prescher@gmail.com) Requirements ...
Initialization: A trait has a default value, which is automatically set as the initial value of an attribute before its first use in a program. Validation: The type of a trait attribute is explicitly declared. The type is evident in the code, and only values that meet a programmer-...

(limit) Set the maximum depth of the Python interpreter stack to limit. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python. The highest possible limit is platform-dependent. A user may need to set the limit higher when she has a program that ...
It isn’t always necessary to compile the regular expression, but it is good practice because doing so can significantly increase a program’s speed. The re.I function ensures that the pattern is case-insensitive and will match both “The” and “the” in the string. The raw string ...
With this setup, if you call your program with$ python main.py -ll DEBUGit will run with the logging level set to DEBUG (so all logger messages will be shown), whereas if you run it with$ python main.py -ll WARNINGit will run at the WARNING level for logging, so all INFO and ...
