We will learn :: + + * How to create lists + * Structure of lists + * Access list elements + * Append elements to lists + * Deleting elements from lists + +List is a compound data type, it can contain data of other data +types. List is also a sequence data type, all the elements are in +order and there order has a meaning. + +We will first create an empty list with no elements. On your IPython +shell type :: + + empty = [] + type(empty) + + +This is an empty list without any elements. + +* Filled lists + +Lets now define a list, nonempty and fill it with some random elements. + +nonempty = ['spam', 'eggs', 100, 1.234] + +Thus the simplest way of creating a list is typing out a sequence +of comma-separated values (items) between square brackets. +All the list items need not have the same data type. + + + +As we can see lists can contain different kinds of data. In the +previous example 'spam' and 'eggs' are strings and 100 and 1.234 +integer and float. Thus we can put elements of heterogenous types in +lists. Thus list themselves can be one of the element types possible +in lists. Thus lists can also contain other lists. Example :: + + list_in_list=[[4,2,3,4],'and', 1, 2, 3, 4] + +We access list elements using the number of index. The +index begins from 0. So for list nonempty, nonempty[0] gives the +first element, nonempty[1] the second element and so on and +nonempty[3] the last element. :: + + nonempty[0] + nonempty[1] + nonempty[3] + +We can also access the elememts from the end using negative indices :: + + nonempty[-1] + nonempty[-2] + nonempty[-4] + +-1 gives the last element which is the 4th element , -2 second to last and -4 gives the fourth +from last element which is first element. + +We can append elements to the end of a list using append command. :: + + nonempty.append('onemore') + nonempty + nonempty.append(6) + nonempty + +As we can see non empty appends 'onemore' and 6 at the end. + + + +Using len function we can check the number of elements in the list +nonempty. In this case it being 6 :: + + len(nonempty) + + + +Just like we can append elements to a list we can also remove them. +There are two ways of doing it. One is by using index. :: + + del(nonempty[1]) + + + +deletes the element at index 1, i.e the second element of the +list, 'eggs'. The other way is removing element by content. Lets say +one wishes to delete 100 from nonempty list the syntax of the command +should be :: + + a.remove(100) + +but what if their were two 100's. To check that lets do a small +experiment. :: + + a.append('spam') + a + a.remove('spam') + a + +If we check a now we will see that the first occurence 'spam' is removed +thus remove removes the first occurence of the element in the sequence +and leaves others untouched. + + +{{{Slide for Summary }}} + + +In this tutorial we came across a sequence data type called lists. :: + + * We learned how to create lists. + * How to access lists. + * Append elements to list. + * Delete Element from list. + * And Checking list length. + + + +{{{ Sponsored by Fossee Slide }}} + +This tutorial was created as a part of FOSSEE project. + +I hope you found this tutorial useful. + +Thank You + + + * Author : Amit Sethi + * First Reviewer : + * Second Reviewer : Nishanth diff --git a/getting-started-with-lists/quickref.tex b/getting-started-with-lists/quickref.tex new file mode 100644 index 0000000..b26d168 --- /dev/null +++ b/getting-started-with-lists/quickref.tex @@ -0,0 +1,8 @@ +Creating a linear array:\\ +{\ex \lstinline| x = linspace(0, 2*pi, 50)|} + +Plotting two variables:\\ +{\ex \lstinline| plot(x, sin(x))|} + +Plotting two lists of equal length x, y:\\ +{\ex \lstinline| plot(x, y)|} diff --git a/getting-started-with-lists/slides.tex b/getting-started-with-lists/slides.tex new file mode 100644 index 0000000..df1462c --- /dev/null +++ b/getting-started-with-lists/slides.tex @@ -0,0 +1,106 @@ +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +%Tutorial slides on Python. +% +% Author: FOSSEE +% Copyright (c) 2009, FOSSEE, IIT Bombay +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% + +\documentclass[14pt,compress]{beamer} +%\documentclass[draft]{beamer} +%\documentclass[compress,handout]{beamer} +%\usepackage{pgfpages} +%\pgfpagesuselayout{2 on 1}[a4paper,border shrink=5mm] + +% Modified from: generic-ornate-15min-45min.de.tex +\mode<presentation> +{ + \usetheme{Warsaw} + \useoutertheme{infolines} + \setbeamercovered{transparent} +} + +\usepackage[english]{babel} +\usepackage[latin1]{inputenc} +%\usepackage{times} +\usepackage[T1]{fontenc} + +\usepackage{ae,aecompl} +\usepackage{mathpazo,courier,euler} +\usepackage[scaled=.95]{helvet} + +\definecolor{darkgreen}{rgb}{0,0.5,0} + +\usepackage{listings} +\lstset{language=Python, + basicstyle=\ttfamily\bfseries, + commentstyle=\color{red}\itshape, + stringstyle=\color{darkgreen}, + showstringspaces=false, + keywordstyle=\color{blue}\bfseries} + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% Macros +\setbeamercolor{emphbar}{bg=blue!20, fg=black} +\newcommand{\emphbar}[1] +{\begin{beamercolorbox}[rounded=true]{emphbar} + {#1} + \end{beamercolorbox} +} +\newcounter{time} +\setcounter{time}{0} +\newcommand{\inctime}[1]{\addtocounter{time}{#1}{\tiny \thetime\ m}} + +\newcommand{\typ}[1]{\lstinline{#1}} + +\newcommand{\kwrd}[1]{ \texttt{\textbf{\color{blue}{#1}}} } + +% Title page +\title{Your Title Here} + +\author[FOSSEE] {FOSSEE} + +\institute[IIT Bombay] {Department of Aerospace Engineering\\IIT Bombay} +\date{} + +% DOCUMENT STARTS +\begin{document} + +\begin{frame} + \maketitle +\end{frame} + +\begin{frame}[fragile] + \frametitle{Outline} + \begin{itemize} + \item + \end{itemize} +\end{frame} + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +%% All other slides here. %% +%% The same slides will be used in a classroom setting. %% +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% + +\begin{frame}[fragile] + \frametitle{Summary} + \begin{itemize} + \item + \end{itemize} +\end{frame} + +\begin{frame} + \frametitle{Thank you!} + \begin{block}{} + \begin{center} + This spoken tutorial has been produced by the + \textcolor{blue}{FOSSEE} team, which is funded by the + \end{center} + \begin{center} + \textcolor{blue}{National Mission on Education through \\ + Information \& Communication Technology \\ + MHRD, Govt. of India}. + \end{center} + \end{block} +\end{frame} + +\end{document} |
