海外TECH	DEV Community	Learning Python-Basic course: Day 20, HashTables via Dictionaries	https://dev.to/aatmaj/learning-python-basic-course-day-20-hashtables-via-dictionaries-3nf1	Learning Python Basic course Day HashTables via Dictionaries Hashtables and information retrievalThe central theme behind hash tables is smart information storage and retrieval The data must be stored in such a manner that it becomes very easy to search it Suppose we want to store a data of any thousand numbers ranging from one to a million Using hashtables we can efficiently store these numbers in a way which makes it easy for searching This is possible only if we map the values to keys The idea of hash table is to allow different possibilities of keys that might over to be mapped to the same location in an array This is done with the help of hashfunctions The hash function takes in a value and maps it to a key Example we might take the hash function as taking only the last three digits of the number So will go to the position while will go to In case of two numbers have same set of last three digits we can use different algorithms to resolve collision One way to do that is using chained hashtables or linked hash tables In this lists are present in the hashtables instead of numeric values where the values can be appended The example below will make things more clear In case you are not familiar with hashtables please visit the following references Dev toGeeks For GeeksHacker EarthYoutubeJava pointProgramitzTutorials PointWikipediaIf anyone has more references then please comment below Simple hashtableLet us now see how to make a simple hashtable from using a dictionary The user enters say five values and we map them to a table of length ten If the values of the keys overlap then error message is generated and new value is ignored This collisionj management will be handled by the next version of hashtable i e linked hashtables For this program we use a simple hashfunction given be the modulus operator as key value lengtha for i in range b int input Please enter an integer key b very simple hash function for length try int a key to check if the element is already present in the position or not print error value occupied except a key b print a OUTPUT Please enter an integer Please enter an integer Please enter an integer Please enter an integer error value occupied Please enter an integer Exercise Modify the above code to map Unicode characters to the hashtable Linked hashtable We now create a linked hashtable i e hashtable of lists This way we solve the issue of the keys in the same position If there are multiple values for the same list then the values are appended on a list rather than ignoring them This method is used for fast data retrievala for i in range b int input Please enter a number key b try append to original list exists if key not in a key a key append b except make a new list a key b print a Please enter a number Please enter a number Please enter a number Please enter a number Please enter a number Please enter a number Please enter a number Please enter a number Please enter a number Please enter a number retrieving data from the hashtableWe can retrieve the data from the hashtable very efficiently In the same way as we added the data we now will remove and display it b int input Please enter the value key b print a key pop b Answers as usual in the learning python repositoryHashtables are one of the many many data structures present For more information related to data structures and algorithms please visit this series of blogs Data structures blog series by Aya Bouchiha on Dev to️So friends that s all for now Follow me on GitHub for updates	2021-07-22 04:44:54
