OverTheTopTechniquesInPython

UNDER PROGRESS

Simplifying commonly used techniques for more optimized representation.

Python is a God's boon for the programmer's who belong to c,c++,java background. Similarly very easy to learn if you're trying to learn programming as a beginner.

You would've already figured out what's the purpose of this repo,
yes it's about simplified approaches toward daily use case techniques and methodology.
I've previously posted some repository's regarding the similar use case like

• swapping-numbers
• pattern-printing which consists of a total 6 repos as per today (day this repo is posted).
• Removing duplicates from a list program inside the given python file.
  BTW you can check out the Python_Data_Structure_Cheat_Sheet created by me for more detailed view of how they work.

Let's get to the topics I covered in this repo,

concatenating strings

string reverse

combining lists using ZIP() function

list to dict using zip()

The _ operator

Multiple user input

The Walrus(:=) operator

Passing N no.of arguments in a function

passing values into tuples

concatenating strings

When we take input from user and store every char as a seperate element in a list we don't have to use a loop to join them all. using join() command we can achieve that easily

my_input = ["h","e","l","l","o"]
my_output = "".join(my_input)
print(my_output)

output: hello

That's how it's done.

string reverse

This : is the Slice operator in python. lemme shoe how to reverse a string using it.

    my_string = "im healthy and happy"
    print(my_string[::-1])
    
    output: yppah dna yhtlaeh mi

Using ZIP() function for list

We can add multiple lists together if they all have the same length.

    list_1 = ["you","so"]
    list_2 = ["are","smart"]
    for list_1,list_2 in zip(list_1,list_2):
        print(list_1,list_2)
        
        output:     you are
                    so smart

Walrus operator

Note: In order to make this operator work you need to have the latest python version, which is availabe on official python website.

The walrus operator is used to assign value and initialize at the same time while condition checking, therefore optimizing the code.

    my_list = [1,2,3,4,5]
    if (n:=len(my_list)>4):
        print(n)
        
        Output: True
