A python dictionary is another mutable container model, and can store any type of object, such as strings, numbers, tuples, and other container models.First, create a dictionaryA dictionary consists of a pair of keys and corresponding values. Dictionaries are also referred to as associative arrays or hash tables. The basic syntax is as follows:Dict = {'Alice'2341'Beth ' '9102'Cecil'3258' }You can also creat

OverviewDictionnary (dictionary) is the most commonly used data type of Python, which is identified by the square brackets {}, whose elements correspond to Key-value, key and value are separated by a colon: split open, let's look at a basic dictionary creation example:Dict = {u"key1": U"value1", u"key2" : U"value2"}Or create it like this:Dict = {12:u" Blog Park ", u"cnblog": U" Gubei " }Built-in functionsTh

Python data types-tuples, commonly used dictionary operations, python data type dictionaryTuples The Python tuples are similar to the list. The difference is thatThe elements of the tuples cannot be modified.. The tuples use parentheses, And the list uses square brackets. Creating tuples is simple. You only need to add elements in brackets and separate them with commas. tp=(1,2,3,'a','b') A = 'Hello world' # This is defined as str type B = ('Hello Wor

same hash table item (or hash bucket) in order to find it. Then, a brief analysis of the search efficiency of the three (assuming the number of words N, the average length of words is D):(1) Exhaustive method, obviously, to traverse n words, each word consumes the string comparison time is O (d), so the total time complexity of O (DN);(2) The balance looks for the binary tree, looks for a word the time is O (logn), then the total lookup time complexity is O (DLOGN);(3) Hash table, calculates th

Tuple definitionA tuple is another data type, similar to a list.The tuple is identified with a "()". The inner elements are separated by commas. However, an element cannot be assigned two times, which is equivalent to a read-only list.Example:tuple = (' ABCD ', 786, 2.23, ' John ', 70.2)list = [' ABCD ', 786, 2.23, ' John ', 70.2]Tuple[2] = 1000 # tuples are illegal to applyList[2] = 1000 # is a legitimate application in the listPrint tuple * 2 # output tuple two timesDictionary definitionsThe
