In python, variables are just names that can be attached to objects in memory. This is in sharp contrast with languages like C, where a variable is a named region of memory where data can be stored. Assignment to a variable name - T in this case - simply changes which object the name refers to, without altering the underlying object in any way.

If you are coming from other programming languages (like C), most likely  Jul 24, 2018 In this tutorial, you will learn exclusively about the index() function. Python also provides many functions or methods that you can use to work with lists. [i for i, n in enumerate(list_numbers) if n == 3] # List comprehension Zero-based numbering or index origin = 0 is a way of numbering in which the initial element of The indexing expression for a 1-based index would then be: a ′ + s × i. Hence, the efficiency benefit at run time of zero-based indexing is not  Python 3 - List index() Method - The index() method returns the lowest index in list that obj appears. A list is a Python data type that can store multiple pieces of information, in order, and In general, if you write del some_list[i:j] , you delete the items from index i

Indices in python start counting from zero. So the index of letter e in "Hello" is 1. Try to run this line of code: print "Hello".find("e"); It should return you 1. You can further play with it an run it again what it does. Try to replace "e" with "H", next try something that isn't in "Hello". A Computer Science portal for geeks. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Python List Index() A data structure is a way to organize and store data that enables efficient access and modification. Lists are a type of data structure that store a collection of heterogeneous items. Python String index() The index() method returns the index of a substring inside the string (if found). If the substring is not found, it raises an exception. Also note that zip in Python 2 returns a list but zip in Python 3 returns a lazy iterable. In Python 2, itertools.izip is equivalent to the newer Python 3 zip function. Looping cheat sheet. Here’s a very short looping cheat sheet that might help you remember the preferred construct for each of these three looping scenarios. Python string method index() determines if string str occurs in string or in a substring of string if starting index beg and ending index end are given. This method is same as find(), but raises an exception if sub is not found. Syntax str.index(str, beg = 0 end = len(string)) Parameters. str − This specifies the string to be searched.
