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

Show the Outline Slide }}} + +Here we will discuss plotting Experimental data. + +1. We will see how we can represent a sequence of numbers in Python. + +2. We will also become fimiliar with elementwise squaring of such a +sequence. + +3.

We shall be plotting L and T^2 values. + + +First we will have to initiate L and T values. We initiate them as sequence +of values. To tell ipython a sequence of values we write the sequence in +comma seperated values inside two square brackets. This is also called List +so to create two sequences + +L,t type in ipython shell. :: + + In []: L = [0.1, 0.2, 0.3, 0.4, 0.5,0.6, 0.7, 0.8, 0.9] + + In []: t= [0.69, 0.90, 1.19,1.30, 1.47, 1.58, 1.77, 1.83, 1.94] + + + +To obtain the square of sequence t we will use the function square +with argument t.This is saved into the variable tsquare.:: + + In []: tsquare=square(t) + + array([ 0.4761, 0.81 , 1.4161, 1.69 , 2.1609, 2.4964, 3.1329, + 3.3489, 3.7636]) + + +Now to plot L vs T^2 we will simply type :: + + In []: plot(L,t,.) + +'.' here represents to plot use small dots for the point. :: + + In []: clf() + +You can also specify 'o' for big dots.:: + + In []: plot(L,t,o) + + In []: clf() + + +{{{ Slide with Error data included }}} + + +Now we shall try and take into account error into our plots . The +Error values for L and T are on your screen.We shall again intialize +the sequence values in the same manner as we did for L and t :: + + In []: delta_L= [0.08,0.09,0.07,0.05,0.06,0.00,0.06,0.06,0.01] + + In []: delta_T= [0.04,0.08,0.11,0.05,0.03,0.03,0.01,0.07,0.01] + + + +Now to plot L vs T^2 with an error bar we use the function errorbar() + +The syntax of the command is as given on the screen. :: + + + In []: errorbar(L,tsquare,xerr=delta_L, yerr=delta_T, fmt='b.') + +This gives a plot with error bar for x and y axis. The dots are of blue color. The parameters xerr and yerr are error on x and y axis and fmt is the format of the plot. + + +similarly we can draw the same error bar with big red dots just change +the parameters to fmt to 'ro'. :: + + In []: clf() + In []: errorbar(L,tsquare,xerr=delta_L, yerr=delta_T, fmt='ro') + + + +thats it. you can explore other options to errorbar using the documentation +of errorbar.:: + + In []: errorbar? + + +{{{ Summary Slides }}} + +In this tutorial we have learnt : + +1. How to declare a sequence of number , specifically the kind of sequence we learned was a list. + +2. Plotting experimental data extending our knowledge from mathematical functions. + +3. The various options available for plotting dots instead of lines. + +4. Plotting experimental data such that we can also represent error.
