Python is a high-level, interpreted, interactive and object-oriented scripting language. Frozen sets in Python are immutable objects that only support methods and operators that produce a result without affecting the frozen set or sets to which they are applied. #!/usr/bin/python var1 = 100 if var1: print "1 - Got a true expression value" print var1 else: print "1 - Got a false expression value" print var1 var2 = 0 if var2: print "2 - Got a true expression value" print var2 else: print "2 - Got a false expression value" print var2 print "Good bye!" Python was officially made available to public in 1991, so that the official data of birth of Python Language is : Feb 20 1991. These operators compare the values on either sides of them and decide the relation among them. Raise KeyError if the set is empty, Updates a set with the union of itself and others, Returns the difference of two or more sets as a new set, Removes all elements of another set from this set, Removes an element from set if it is a member.

This tutorial is designed for software programmers who are willing to learn python and want to do practical examples on python language.

Python is a general-purpose interpreted, interactive, object-oriented, and high-level programming language. Python is a Beginner's Language − Python is a great language for the beginner-level programmers and supports the development of a wide range of applications from simple text processing to WWW browsers to games. Python is designed to be highly readable.

GUI Programming − Python supports GUI applications that can be created and ported to many system calls, libraries and windows systems, such as Windows MFC, Macintosh, and the X Window system of Unix. It can be used as a scripting language or can be compiled to byte-code for building large applications. It is a standard Python interface to the Tk GUI toolkit shipped with Python. Order of elements in a set is undefined and is unchangeable.

It uses English keywords frequently where as other languages use punctuation, and it has fewer syntactical constructions than other languages. Langton’s Ant is a 4-state two-dimensional universal Turing machine.

You do not need to compile your program before executing it. However, unlike else, for which there can be at most one statement, there can be an arbitrary number of elif statements following an if.

These modules enable programmers to add to or customize their tools to be more efficient. Python – How to merge two dict in Python ? It was created by Guido van Rossum during 1985- 1990. Elements of a set can be added and deleted, elements of the set can be iterated, various standard operations (union, intersection, difference) can be performed on sets. Python is a programming language. Python is a general purpose high level programming language. Send your feedback at contact@tutorialspoint.com Thanks tutorialspoint Databases − Python provides interfaces to all major commercial databases. Note – If the set is unordered then there’s no such way to determine which element is popped by using the pop() function.

Python Comparison Operators Example. Set in Python is equivalent to sets in mathematics. The syntax of the if...else statement is −, When the above code is executed, it produces the following result −. Python is designed to be highly readable.

Portable − Python can run on a wide variety of hardware platforms and has the same interface on all platforms. Python is Object-Oriented − Python supports Object-Oriented style or technique of programming that encapsulates code within objects. What is the maximum possible value of an integer in Python ? Extendable − You can add low-level modules to the Python interpreter. Write and run Python code using our online compiler (interpreter).

It was developed by Guido Van Rossam in 1989 while working in National Research Institute at Netherlands. It is basically an ant, sitting on a square lattice of cells, which are initially white.

Only one element at a time can be added to the set by using add() method, loops are used to add multiple elements at a time with the use of add() method whereas for addition of two or more elements Update() method is used. Use Code "COMPUTER" to GET EXTRA FLAT 15% OFF Ends In Categories This tutorial is designed for software programmers who are willing to learn python and want to do practical examples on python language. Python is Object-Oriented − Python supports Object-Oriented style or technique of programming that encapsulates code within objects.

Reading an excel file using Python Using xlrd module, one can retrieve information from a spreadsheet. It supports functional and structured programming methods as well as OOP.

Besides that, the major advantage of using a set, as opposed to a list, is that it has a highly optimized method for checking whether a specific element is contained in the set. Please refer to this link for our Python 2 tutorial. Hence the Python Language consider to be a combination of all these programming features.

A basic understanding of any of the programming languages is a plus. Previous Page. What are the different ways to Sort Objects in Python ? The order of elements in a set is undefined though it may consist of various elements. Out of all the GUI methods, tkinter is most commonly used method.
