  Python Module A moduleis a logical organization of Python code. Related code are grouped into a module which makes the code easier to understand and use. Any python module is an object with different attributes which can be bind and referenced. Simply, it is a file containing a set of functions which can be included in our application. Python provide inbuilt standard modules, like math, random etc. Visit : python.mykvs.in for regular updates

  import - Pythonmodules can get access to code from another module by importing the file/function using import. import math print(math.pi) from - pi as a whole can be imported into our initial code, rather than importing the whole module. from math import pi print(pi) In the above code module, math is not imported, rather just pi has been imported as a variable. All the functions and constants can be imported using *. from module_name import * print(pi) print(factorial(6)) Python Module Visit : python.mykvs.in for regular updates

  math module The mathmodule is a standard module in Python and is always available. To use mathematical functions under this module, we have to import the module using import math statement. How to use math function import math math.sqrt(4) Python Module Visit : python.mykvs.in for regular updates

  math.sqrt() The math.sqrt() methodreturns the square root of a given number. >>>math.sqrt(100) 10.0 >>>math.sqrt(3) 1.7320508075688772 The ceil() function approximates the given number to the smallest integer, greater than or equal to the given floating point number. The floor() function returns the largest integer less than or equal to the given number. >>>math.ceil(4.5867) 5 >>>math.floor(4.5687) 4 math.pow() The math.pow() method receives two float arguments, raises the first to the second and returns the result. In other words, pow(2,3) is equivalent to 2**3. >>>math.pow(2,4) 16.0 Python Module Visit : python.mykvs.in for regular updates
• 6.
  math.fabs() Returns the absolutevalue of x >>> import math >>> math.fabs(-5.5) 5.5 The math module contains functions for calculating various trigonometric ratios for a given angle. The functions (sin, cos, tan, etc.) need the angle in radians as an argument. >>> math.sin(270) -0.1760459464712114 Python Module Visit : python.mykvs.in for regular updates
• 7.
  Random Module The randommodule provides access to functions that support many operations.Perhaps the most important thing is that it allows us to generate random numbers. random.randint() Randint accepts two parameters: a lowest and a highest number. import random print (random.randint(0, 5)) This will output either 1, 2, 3, 4 or 5. random.random() Genereate random number from 0.01 to 1.If we want a larger number, we can multiply it. import random print(random.random() * 100) Python Module Visit : python.mykvs.in for regular updates
• 8.
  randrange() generate random numbersfrom a specified range and also allowing rooms for steps to be included. Syntax : random.randrange(start(opt),stop,step(opt)) import random # Using randrange() to generate numbers from 0-100 print ("Random number from 0-100 is : ",end="") print (random.randrange(100)) # Using randrange() to generate numbers from 50-100 print ("Random number from 50-100 is : ",end="") print (random.randrange(50,100)) # Using randrange() to generate numbers from 50-100 # skipping 5 print ("Random number from 50-100 skip 5 is : ",end="") print (random.randrange(50,100,5)) OUTPUT Random number from 0-100 is : 27 Random number from 50-100 is : 48 Random number from 50-100 skip 5 is : 80 Python Module Visit : python.mykvs.in for regular updates

  statistics module This moduleprovides functions for calculating mathematical statistics of numeric (Real- valued) data. statistics.mean(data) Return the sample arithmetic mean of data which can be a sequence or iterator.The arithmetic mean is the sum of the data divided by the number of data points(AVERAGE). import statistics print(statistics.mean([5,3,2])) OUTPUT 3.3333333333333335 statistics.median(data) Return the median (middle value) of numeric data, using the common “mean of middle two” method. If data is empty, StatisticsError is raised. import statistics print(statistics.median([5,5,4,4,3,3,2,2])) OUTPUT 3.5 Python Module Visit : python.mykvs.in for regular updates
• 10.
  statistics.mode(data) Return the mostcommon data point from discrete or nominal data. The mode (when it exists) is the most typical value, and is a robust measure of central location.If data is empty, or if there is not exactly one most common value, StatisticsError is raised. import statistics print(statistics.mode([1, 1, 2, 3, 3, 3, 3, 4])) OUTPUT 3 Python Module Visit : python.mykvs.in for regular updates
