Introduction To Python
Python is a widely-used, interpreted, object-oriented, and high-level programming language with dynamic semantics, used for general-purpose programming. It was created by Guido van Rossum, and first released on February 20, 1991.
Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. It is also used to create various machine learning algorithm, and helps in Artificial Intelligence. Python is a general purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today. A survey conducted by industry analyst firm RedMonk found that it was the most popular programming language among developers in 2020.

Word Order in python – HackerRank Solution
You are given n words. Some words may repeat. For each word, output its number of occurrences. The output order should correspond with the input order of appearance of the word. See the sample input/output for clarification.
Note: Each input line ends with a “\n” character.
- 1 <= n <= 10^5
The sum of the lengths of all the words do not exceed 10^6
All the words are composed of lowercase English letters only.
Input Format :
The first line contains the integer, n.
The next n lines each contain a word.
Output Format :
Output 2 lines.
On the first line, output the number of distinct words from the input.
On the second line, output the number of occurrences for each distinct word according to their appearance in the input.
Sample Input :
4 bcdef abcdefg bcde bcdef
Sample Output :
3 2 1 1
There are 3 distinct words. Here, “bcdef” appears twice in the input at the first and last positions. The other words appear once each. The order of the first appearances are “bcdef”, “abcdefg” and “bcde” which corresponds to the output.
