Learning the Enumerate()


After, the list lets learn about the intriguing enumerate function in python. Python is the favorite programming language of many developers; contrary to popular belief, it isn’t merely a “technology for newbies” its power and functionality make it an excellent tool for a plethora of tasks. Python is renowned for its collection of libraries, modules, and functions that it comes packaged with and enumerate() is something we should learn in detail.


          So, what is enumerate function?

          Python's enumerate function is tool that allows us to create a counter alongside values we're iterating over: as part of a loop, for example.

Enumerate takes an iterable type as its first positional argument, such as a list, and returns an enumerate object containing a number of tuples: one for each item in the iterable. Each tuple contains an integer counter, and a value from the iterable.

If we ever have to iterate through a list while keeping track of the index of each element, enumerate will come in handy.

Let’s see through an example:

words = ['all', 'your', 'base']
for idx, word in enumerate(words):
    print(idx, word)
print(list(enumerate(words)))# Output:
# 0 all
# 1 your
# 2 base
# [(0, 'all'), (1, 'your'), (2, 'base')]

 Enumerate returns an iterator object instead of a list. The iterator serves to save memory, especially when your input list is large.

So, this is how enumerate function comes handy when we need to keep the count of iteration when dealing with lot of iterations.

Further into the lists..

So, let's continue our learnings about the lists in python!      Why and how  to use list comprehension ? List is one of the most useful collection data type in python.It is a collection which is ordered and changeable.It Allows duplicate members.   Many of us would have thought of what if we want to manipulate each and every  list element? Suppose you are given a list of numbers and you want to add 1 to each element in your list: my_list = [1, 3, 3, 7] my_list_plus_one = my_list + 1  and if you have thought of some code like above then its not gonna  work. You would get this error:   TypeError : can only concatenate list (not "int") to list.  Python thinks that you want to add a list and an integer together, which doesn’t make any sense. So how do we manipulate the list? The answer is using list comprehension syntax. Example: my_list_plus_one = [num + 1 for num in my_list] print(my_list_plus_one)  # Output: [2, 4, 4, 8] Essentially...

Journey towards Creating Hangman.

I love when people take a sophisticated tool and use it to play video games. Take Unity for example. I first saw my friends created a game in Unity, which was an Virtual reality game. My friends Vivek and Payas then inspired me to more efficiently waste time in creating something of my own like their VR game. Rather than jumping directly to a VR game so we thought to start something from the basics. So, the other day I had an immense amount of college work to do and decided it was the perfect time to make a hangman game.  So, What is hangman? In its purest form, hangman is a word game played between two people. One person selects a secret word, and the other tries to determine the word by guessing it letter-by-letter. The player with the secret writes a series of dashes, one representing each letter in the solution. Initially, no information is known about the target word, other than its length. The solver calls out letters, one-by-one. If a called letter appears in the solutio...
