I created a fun password cracker using literal brute force, searching each character to see if it matches an ASCII character
0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ . The password is randomly generated and will vary from 100,000 to 250,000 characters long. I use a wrapper timeit function to time the function and the output is a basic print statement using .format() :

An example output (without the password):

In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password.

Dec 22, 2014 Brute force password cracking algorithm. Brute force password cracking algorithm challenge. Let us celebrate Christmas with friendly rivalry. The Rules - 1) Must be written in C 2) Program must compile, run and work before posting your solution 3) Program must be documented, not excessively, but why you went for that approach. I am doing an assignment for class which I have to create a brute force password cracker in java. Write a function using Recursion to crack a password. The password is of unknown length (maximum 10) and is made up of capital letters and digits. Sep 27, 2019 Password cracking is the process of attempting to gain Unauthorized access to restricted systems using common passwords or algorithms that guess passwords. In other words, it’s an art of obtaining the correct password that gives access to a system protected by an authentication method. Password cracking employs a number of techniques to achieve its goals.

I'll answer your first question separately. However, since your second and third questions are closely related, I'll give the same answers to both questions.
Am I following coding standards for Python 2 (like PEP8)
For the most part, your code complies with PEP8,
The only thing I'd suggest is to break some of your longer statements up - such as your
print statement at the end of your script - onto separate lines, with each separate line being indented.
However, even if sometimes you choose not to comply with a certain coding standard, make sure you are consistent with your naming conventions. I've seen Python code which is written Java style, but is still easy to read because the author was consistent in their style.

Is there any way to make my code more 'Pythonic' (like a native Python coder)? and Is there anyway to improve performance, readability, etc.

Password Cracking Algorithm Python
Whenever you are doing string addition in Python, you are probably doing it wrong. It is very slow, due to strings being immutable. Because of this Python will have to create a new string everytime you do string addition and copy over the content of the two strings you are adding.
As a fix, just use
list and str.join . Also, creating a password from a possible list of characters is something you might want to do again, so I would put it into a function.
This can be even further simplified using
random.sample :
