Sentiment analysis is a method of deriving meaning from text. It is a type of natural language processing method which determines whether a word, sentence, paragraph, document is positive or negative. Each document is given a positive or negative score based on the number of positive and negative words The ability to categorize opinions expressed in the text of tweets—and especially to determine whether the writer's attitude is positive, negative, or neutral—is highly valuable. In this guide, we will use the process known as sentiment analysis to categorize the opinions of people on Twitter towards a hypothetical topic called #hashtag Step 3: Getting Tweets With Keyword or Hashtag #Sentiment Analysis def percentage(part,whole): return 100 * float(part)/float(whole) keyword = input(Please enter keyword or hashtag to search: ) noOfTweet = int(input (Please enter how many tweets to analyze: )) tweets = tweepy.Cursor(api.search, q=keyword).items(noOfTweet) positive = 0 negative = 0 neutral = 0 polarity = 0 tweet_list =  neutral_list =  negative_list =  positive_list =  for tweet in tweets: #.

In general, hash tables store key-value pairs and the key is generated using a hash function. Hash tables or has maps in Python are implemented through the built-in dictionary data type. The keys of a dictionary in Python are generated by a hashing function. The elements of a dictionary are not ordered and they can be changed It's the important reason why Hash tables are utilized as the look-up table data structure. This is due to the reliability and faster act during the storage of key-value pairs. Hashmaps or Hash Tables in Python are implemented via the built-in data type. The keys of the built-in data type are generated with the help of a hashing function Few data-structures are more ubiquitous in real-world development than the hash table. Nearly every major programming features an implementation in its standard library or built into the runtime. Yet, there is no conclusive best strategy to implement one and the major programming languages diverge widely in their implementations! I did a survey of the Hash map implementations in Go, Python.
hashID is a tool written in Python 3 which supports the identification of over 220 unique hash types using regular expressions. A detailed list of supported hashes can be found here.

Hash tables are based on the concept of hash, which means using a hash function used to map key and values. Since it is used to map key and value pairs, it is commonly known as a hashmap. Hash Tables using Python. The hash table implementation is based on the concept of key and value mapping just like dictionaries in Python Hashing Strings with Python. A hash function is a function that takes input of a variable length sequence of bytes and converts it to a fixed length sequence. It is a one way function. This means if f is the hashing function, calculating f (x) is pretty fast and simple, but trying to obtain x again will take years Hashids is a small open-source library that generates short, unique, non-sequential ids from numbers. It converts numbers like 347 into strings like yr8, or array of numbers like [27, 986] into 3kTMd. You can also decode those ids back To perform this analysis, the Center first queried Twitter's Gnip API for a 20% sample of tweets mentioning four hashtags related to these topics (the specific hashtags include #BlackLivesMatter, #AllLivesMatter, #BlueLivesMatter and #BLM) during five specific high-volume points in time between 2014 and 2018 that coincided with major increases in the use of these hashtags
