👉 What is Python Data Structures?
You can think of a data structure as a way of organizing and storing data such that we can access and modify it efficiently.
We have primitive data types like integers, floats, Booleans, and strings.

👉 What is Python List?
A list in Python is a heterogeneous container for items. This would remind you of an array in C++, but since Python does not support arrays, we have Python Lists.

👉 Python Tuple
This Python Data Structure is like a, like a list in Python, is a heterogeneous container for items.
But the major difference between the two (tuple and list) is that a list is mutable, but a tuple is immutable.
This means that while you can reassign or delete an entire tuple, you cannot do the same to a single item or a slice.

👉 Python Dictionaries
Finally, we will take a look at Python dictionaries. Think of a real-life dictionary. What is it used for? It holds word-meaning pairs. Likewise, a Python dictionary holds key-value pairs. However, you may not use an unhashable item as a key.
To declare a Python dictionary, we use curly braces. But since it has key-value pairs instead of single values, this differentiates a dictionary from a set.

What is Python Loop?
When you want some statements to execute a hundred times, you don’t repeat them 100 times.
Think of when you want to print numbers 1 to 99. Or that you want to say Hello to 99 friends.
In such a case, you can use loops in python.
Here, we will discuss 4 types of Python Loop:
Python For Loop
Python While Loop
Python Loop Control Statements
Nested For Loop in Python
Python While Loop
A while loop in python iterates till its condition becomes False. In other words, it executes the statements under itself while the condition it takes is True.
Python For Loop
Python for loop can iterate over a sequence of items. The structure of a for loop in Python is different than that in C++ or Java.
That is, for(int i=0;i<n;i++) won’t work here. In Python, we use the ‘in’ keyword.
Nested for Loops in Python
You can also nest a loop inside another. You can put a for loop inside a while, or a while inside a for, or a for inside a for, or a while inside a while.
Or you can put a loop inside a loop inside a loop. You can go as far as you want.
Loop Control Statements in Python
Sometimes, you may want to break out of normal execution in a loop.
For this, we have three keywords in Python- break, continue, and Python

Source Code of Getting WiFi Passwords 👇👇-

# importing subprocess
import subprocess
 
# getting meta data
meta_data = subprocess.check_output(['netsh', 'wlan', 'show', 'profiles'])
 
# decoding meta data
data = meta_data.decode('utf-8', errors ="backslashreplace")
 
# splitting data by line by line
data = data.split('\n')
 
# creating a list of profiles
profiles = []
 
# traverse the data
for i in data:
     
    # find "All User Profile" in each item
    if "All User Profile" in i :
         
        # if found
        # split the item
        i = i.split(":")
         
        # item at index 1 will be the wifi name
        i = i[1]
         
        # formatting the name
        # first and last character is use less
        i = i[1:-1]
         
        # appending the wifi name in the list
        profiles.append(i)
         
 
# printing heading       
print("{:<30}| {:<}".format("Wi-Fi Name", "Password"))
print("----------------------------------------------")
 
# traversing the profiles       
for i in profiles:
     
    # try catch block begins
    # try block
    try:
        # getting meta data with password using wifi name
        results = subprocess.check_output(['netsh', 'wlan', 'show', 'profile', i, 'key = clear'])
         
        # decoding and splitting data line by line
        results = results.decode('utf-8', errors ="backslashreplace")
        results = results.split('\n')
         
        # finding password from the result list
        results = [b.split(":")[1][1:-1] for b in results if "Key Content" in b]
         
        # if there is password it will print the pass word
        try:
            print("{:<30}| {:<}".format(i, results[0]))
         
        # else it will print blank in front of pass word
        except IndexError:
            print("{:<30}| {:<}".format(i, ""))
             
     
             
    # called when this process get failed
    except subprocess.CalledProcessError:
        print("Encoding Error Occurred")
