Textual content Processing in Python describes options for manipulation of textual content utilizing the Python programming language. on the broadest point, textual content processing is just taking textual info and doing anything with it. this may be restructuring or reformatting it, extracting smaller bits of data from it, or acting calculations that depend upon the textual content.
Learn IPython for interactive Python programming, high-performance numerical computing, and knowledge visualization.
• a realistic step by step educational for you to assist you to exchange the Python console with the robust IPython command-line interface;
• Use the IPython computer to modernize how you have interaction with Python;
• practice hugely effective computations with NumPy and Pandas;
• Optimize your code utilizing parallel computing and Cython.
You already use Python as a scripting language, yet were you aware it's also more and more used for medical computing and information research? Interactive programming is key in such exploratory initiatives and IPython is the fitting device for that. as soon as you’ve learnt it, you won't have the capacity to stay with no it.
Learning IPython for Interactive Computing and knowledge Visualization is a realistic, hands-on, example-driven educational to significantly increase your productiveness in the course of interactive Python classes, and indicates you ways to successfully use IPython for interactive computing and information analysis.
This e-book covers all features of IPython, from the hugely robust interactive Python console to the numerical and visualization beneficial properties which are quite often linked to IPython.
You will learn the way IPython allows you to practice effective vectorized computations, via examples masking numerical simulations with NumPy, information research with Pandas, and visualization with Matplotlib. additionally, you will observe how IPython may be with ease used to optimize your code utilizing parallel computing and dynamic compilation in C with Cython.
Learning IPython for Interactive Computing and information Visualization will let you optimize your productiveness in interactive Python sessions.

Declare the variable as global. The global statement declares one or more variables, separated by commas, to be global. See epydoc for a suggested format. Examples: class SomeClass(object): @classmethod def HelloClass(cls, arg): pass ## HelloClass = classmethod(HelloClass) @staticmethod def HelloStatic(arg): pass ## HelloStatic = staticmethod(HelloStatic) # # Define/implement a decorator. def wrapper(fn): def inner_fn(*args, **kwargs): print '>>' result = fn(*args, **kwargs) print '<<' return result return inner_fn # # Apply a decorator.
The use of classmethods and staticmethod will be explained later in the section on objectoriented programming. Remember that in order to use a function, it must be defined in the current module or imported by the current module or be a builtin. The form that explicitly calls the decorator function (commented out in the example above) is equivalent to the form using the "@" character. 2 lambda Use a lambda, as a convenience, when you need a function that both: is anonymous (does not need a name) and contains only an expression and no statements.
User defined exception classes subclasses of Exception. One answer: You want a user of your code to catch your exception and no others. The exception object (usually an instance of some exception class) is bound to exp. A more "modern" syntax is: except SomeExceptionClass as exp: So: class MyE(ValueError): pass try: raise MyE() except ValueError: print 'caught exception' will print "caught exception", because ValueError is a base class of MyE. html. Solution: class MyE(Exception): Page 50 A Python Book pass ● Write a try:except: statement that raises your exception and also catches it.
