In Chap. 2 you were introduced to the term function . A function is a set of instructions that together perform a single well-defined task. Examples of the many sorts of task that a function could perform are calculating the area of a circle, displaying a particular message on the screen...
And when it comes to reusing code in Python, it all starts and ends with the humblefunction. Take some lines of code, give them a name, and you’ve got a function (which can be reused). Take a collection of functions and package them as a file, and you’ve got amodule(which can...
The module comes with several functions. 我们将演示其中的几个。 We’re just going to demonstrate a couple of them. 例如,如果我想使用pi的值,我会键入math.pi,Python会告诉我pi的值,3.14,依此类推。 For example, if I wanted to use the value of pi, I would type math.pi and Python would ...
Building Python functions allows for the creation of reusable code and is the first step toward writing object-oriented code. In this sample chapter from Cisco Certified DevNet Associate DEVASC 200-901 Official Cert Guide, you will review working with and building Python functions. It also introduc...
Common regular expression functions: re.match(): Matches patterns at the start of strings re.search(): Finds patterns anywhere in strings re.findall(): Returns all non-overlapping matches re.sub(): Substitutes matched patterns with replacement text Threading and multiprocessing Threading and multipro...
Modules candefine functions,classes, andvariablesthat you can reference in other Python.pyfiles or via the Python command line interpreter. In Python, modules are accessed by using theimportstatement. When you do this, you execute the code of the module, keeping the scopes of the definitions so...

Examples to Import Python ModulesNow, we are implementing the operations from the module functions in the below examples:Example 1: menu.pyIn this program all the functions of both modules i.e. mycheck.py/mymath.py are get loaded in menu.py’s memory and have to use module name as ...
Python uses a pseudo-random generator based upon Mersenne Twister algorithm that produces 53-bit precision floats. Functions in this module depend on pseudo-random number generator function random() which generates a random float number between 0.0 and 1.0.random.random(): Returns a random float ...
In this article we work with Python modules. Several examples show how to create and use Python modules. Amoduleis a file containing Python code. Python modules have the.pyextension. Python code can be managed using: functions classes
