I hope whatever you do today you have a great day. I was going to fish but will wait until tomorrow. In my case it will be a nice quiet day at home with the Boss at work saving lives, popping pimples, and everything in between. My plan will be to do a little reorganization of the tackle room and of course to watch some football.
Various ways to iterate over sequences The sequence functions illustrated in 4. We can randomize the contents of a list s before iterating over them, using random. We can convert between these sequence types.
For example, tuple s converts any kind of sequence into a tuple, and list s converts any kind of sequence into a list. We can convert a list of strings to a single string using the join function, e. Some other objects, such as a FreqDist, can be converted into a sequence using list or sorted and support iteration, e.
We can omit the parentheses because the comma has higher precedence than assignment. It is equivalent to the following traditional way of doing such tasks that does not use tuples notice that this method needs a temporary variable tmp. There are also functions that modify the structure of a sequence and which can be handy for language processing.
Thus, zip takes the items of two or more sequences and "zips" them together into a single list of tuples. Given a sequence s, enumerate s returns pairs consisting of an index and the item at that index.
For some NLP tasks it is necessary to cut up a sequence into two or more parts. To do this we decide the location where we want to cut the datathen cut the sequence at that location.
We can also verify that the ratio of the sizes of the two pieces is what we intended. Combining Different Sequence Types Let's combine our knowledge of these three sequence types, together with list comprehensions, to perform the task of sorting the words in a string by their length.
A simple string is actually an object with methods defined on it such as split. We use a list comprehension to build a list of tupleswhere each tuple consists of a number the word length and the word, e.
We use the sort method to sort the list in-place. Finally, we discard the length information and join the words back into a single string. The underscore is just a regular Python variable, but we can use underscore by convention to indicate that we will not use its value. We began by talking about the commonalities in these sequence types, but the above code illustrates important differences in their roles.
First, strings appear at the beginning and the end: Lists and tuples are used in the middle, but for different purposes. A list is typically a sequence of objects all having the same type, of arbitrary length. We often use lists to hold sequences of words. In contrast, a tuple is typically a collection of objects of different types, of fixed length.
We often use a tuple to hold a record, a collection of different fields relating to some entity. This distinction between the use of lists and tuples takes some getting used to, so here is another example: An individual entry is represented as a tuple because it is a collection of objects with different interpretations, such as the orthographic form, the part of speech, and the pronunciations represented in the SAMPA computer-readable phonetic alphabet http: Note that these pronunciations are stored using a list.The Longest Memory is historical fiction depicting life on a Virginian plantation between and The story is told from the viewpoint of several different people using different formats.

As a memory region, a text segment may be placed below the heap or stack in order to prevent heaps and stack overflows from. South Asian arts, the literary, performing, and visual arts of India, Pakistan, Bangladesh, and Sri Lanka..
Despite a history of ethnic, linguistic, and political fragmentation, the people of the Indian subcontinent are unified by a common cultural and ethical outlook; a wealth of ancient textual literature in Sanskrit, Prākrit, and regional languages is a major unifying factor.
