It returns the original text if the string already contains a capital letter at the beginning. If we don't have an empty list as the second value, it will start off with an empty list, which we then append. Note that 2 indicates that only the first two values will be split. Dictionary is one of Python's built-in datatypes. float64 , NumPyrange, arangelinspacestep, array Unpickling is the process of recovering original Python objects from a stored text representation. Python also includes a built-in garbage collector, which recycles all unused memory and makes it available to the heap space. Decorators are typically defined prior to the function they are enhancing. It's a command-line utility that creates a unified interface for installing various Python modules.

Then we write the function to which it is applied, simply placing the decorator function above the function to which it must be applied. The Python Global Interpreter Lock doesn't allow more than one thread to hold the Python interpreter at that particular point in time. This step can also be skipped. Encapsulation is demonstrated through a Python class. Therefore, Python must check the data type of each element every time it uses it. NumPy provides both the flexibility of Python and the speed of well-optimized compiled C code. 1D2D Weban object describing the type of the elements in the array.

Seaborn is a Python library built on top of matplotlib and pandas to ease data plotting. Shallow copy creates a different object and populates it with the references of the child objects within the original object. Inheritance allows one class to gain all of another class's members (for example, attributes and methods). The function returns a 2-d matrix with all non-diagonal terms equal to 0. 5.
