Python Random Module

 

Python Random Module

Python has a built-in module that you can use to make random numbers.

The random module has a set of methods:

MethodDescription
seed()Initialize the random number generator
getstate()Returns the current internal state of the random number generator
setstate()Restores the internal state of the random number generator
getrandbits()Returns a number representing the random bits
randrange()Returns a random number between the given range
randint()Returns a random number between the given range
choice()Returns a random element from the given sequence
choices()Returns a list with a random selection from the given sequence
shuffle()Takes a sequence and returns the sequence in a random order
sample()Returns a given sample of a sequence
random()Returns a random float number between 0 and 1
uniform()Returns a random float number between two given parameters
triangular()Returns a random float number between two given parameters, you can also set a mode parameter to specify the midpoint between the two other parameters
betavariate()Returns a random float number between 0 and 1 based on the Beta distribution (used in statistics)
expovariate()Returns a random float number based on the Exponential distribution (used in statistics)
gammavariate()Returns a random float number based on the Gamma distribution (used in statistics)
gauss()Returns a random float number based on the Gaussian distribution (used in probability theories)
lognormvariate()Returns a random float number based on a log-normal distribution (used in probability theories)
normalvariate()Returns a random float number based on the normal distribution (used in probability theories)
vonmisesvariate()Returns a random float number based on the von Mises distribution (used in directional statistics)
paretovariate()Returns a random float number based on the Pareto distribution (used in probability theories)
weibullvariate()Returns a random float number based on the Weibull distribution (used in statistics)

Python Tuples

  Python  Tuples mytuple = ( "apple" ,  "banana" ,  "cherry" ) Tuple Tuples are used to store multiple items in a single variable. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and  unchangeable . Tuples are written with round brackets. Example Create a Tuple: thistuple = ( "apple" ,  "banana" ,  "cherry" ) print (thistuple) Tuple Items Tuple items are ordered, unchangeable, and allow duplicate values. Tuple items are indexed, the first item has index  [0] , the second item has index  [1]  etc. Ordered When we say that tuples are ordered, it means that the items have a defined order, and that order will not change. Unchangeable Tuples are unchangeable, meaning that we cannot change, add or remove items after the tuple has been created. Allow Duplicates Since tuples...

Python Strings

  Python  Strings  Strings Strings in python are surrounded by either single quotation marks, or double quotation marks. 'hello'  is the same as  "hello" . You can display a string literal with the  print()  function: Example print ( "Hello" ) print ( 'Hello' ) Assign String to a Variable Assigning a string to a variable is done with the variable name followed by an equal sign and the string: Example a =  "Hello" print (a) Multiline Strings You can assign a multiline string to a variable by using three quotes: Example You can use three double quotes: a =  "" "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua." "" print (a) Or three single quotes: Example a =  '' 'Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.' '' print (a) Note:  in the res...

Python Arrays

  Python  Arrays Note:  Python does not have built-in support for Arrays, but  Python Lists  can be used instead. Arrays Note:  This page shows you how to use LISTS as ARRAYS, however, to work with arrays in Python you will have to import a library, like the  NumPy library . Arrays are used to store multiple values in one single variable: Example Create an array containing car names: cars = [ "Ford" ,  "Volvo" ,  "BMW" ] What is an Array? An array is a special variable, which can hold more than one value at a time. If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this: car1 =  "Ford" car2 =  "Volvo" car3 =  "BMW" However, what if you want to loop through the cars and find a specific one? And what if you had not 3 cars, but 300? The solution is an array! An array can hold many values under a single name, and you can access the values by referring to an index nu...
