In particular it doesn't make sense to do mathematical manipulation such as additions or derivations on Python functions. In general, the order of keys/values will depend on memory locations can and will differ between different computers and / or repeated runs on the same computer. One can also create tuples using comprehensions: sage: tuple(i^2 for i in range(10) if i % 2 == 0) (0, 4, 16, 36, 64) A set is a data structure which One can also use square brackets: sage: my_matrix[3,2] # optional - scilab 4.

Using a wide range of spatial, spectral, temporal, and radiometric scales Remote Sensing is a large and diverse field for which this Handbook will be the key research reference. sage: # edit here Nested list comprehensionsÂ¶ List comprehensions can be nested!

It seems to have done the trick! range(i, j) returns [i, i+1, i+2, ..., j-1]; start (!) defaults to 0.

sage: scilab('9')^2 # optional - scilab 81. Foody,Timothy A. We do not need double parentheses for this: sage: sum( i^2 for i in srange(100001) ) 333338333350000 DictionariesÂ¶ A dictionary is another built-in data type. Answers may be verified using Sage.

One can also create lists using list comprehension: [

sage: M[10] # optional - scilab Traceback (most recent call last): ... Exercise: Below are some examples of slicing lists. TypeError: unhashable type: 'list' Another way to add items to a dictionary is with the update() method which updates the dictionary from another dictionary: sage: d = {} sage: d Thank you.

sage: M[2,4] # optional - scilab Traceback (most recent call last): ... The command isinstance(ex, typ) returns whether the expression ex is of type typ. To create a tuple, use parentheses instead of brackets: sage: t = (3, 5, [3,1], (17,[2,3],17), 4) sage: t (3, 5, [3, 1], (17, [2, 3], 17), 4) To create a ExercisesÂ¶ For each of the following sets, compute the list of its elements and their sum.

console()Â¶ Starts Scilab console. A list is a data structure which groups values. Also available in other languages. sage: # edit here What is the index of the first element of L?

sage: # edit here What is L.index(2)? Unlike lists, which are indexed by a range of numbers starting at 0, dictionaries are indexed by keys, which can be any immutable objects. A tuple is immutable (one cannot change it) but it is hashable (see below). Created using Sphinx 1.4.4.

As the university's chief executive officer, President M. Warner is Professor of Geology and Geography at West Virginia University, in Morgantown, West Virginia, USA. Inequality is !=. One creates dictionaries using the constructor dict, or using the syntax: {key1 : value1, key2 : value2 ...} For example: sage: age = {'toto' : 8, 'mom' : 27}; age

These are exactly the valid indices for a list of 4 elements. The presented code, written in core components of Sage, are backward compatible, i.e., easily applicable to other software systems such as MathematicaÂ®. Example: To create a list of the squares of the prime numbers between 1 and 100, we use a list comprehension as follows.
