Python String Methods

1. `upper()` and `lower()`


s = "Hello, World!"
print(s.upper())  # Output: HELLO, WORLD!
print(s.lower())  # Output: hello, world!

2. `strip()`, `lstrip()`, and `rstrip()`


s = "   Hello, World!   "
print(s.strip())  # Output: "Hello, World!"
print(s.lstrip()) # Output: "Hello, World!   "
print(s.rstrip()) # Output: "   Hello, World!"

3. `split()` and `join()`


s = "Hello, World!"
words = s.split(", ")
print(words)  # Output: ['Hello', 'World!']
print(" - ".join(words))  # Output: Hello - World!

4. `find()`, `rfind()`, `index()`, and `rindex()`


s = "Hello, World!"
print(s.find("o"))  # Output: 4
print(s.rfind("o"))  # Output: 8
print(s.index("World"))  # Output: 7

5. `replace()`


s = "Hello, World!"
print(s.replace("World", "Python"))  # Output: Hello, Python!

MultiProcessing in Python

  Learning Sections          show MultiProcessing in Python Multiprocessing in Python involves using the multiprocessing module to run multiple processes concurrently, taking advantage of multiple CPU cores. This module provides a higher level of concurrency than threading and is especially useful for CPU-bound tasks. Creating Processes You can create and start a new process by using the multiprocessing module: import multiprocessing def print_numbers (): for i in range ( 10 ): print ( i ) p1 = multiprocessing.Process ( target = print_numbers ) p1 . start () p1 . join () # Wait for the process to complete Using Process Pools The multiprocessing module provides a Pool class, which allows you to manage a pool of worker processes: from multiprocessing import Pool def square ( n ): return n * n with Pool ( 4 ) as pool : result = pool.map ( square , range (...

Conclusion and where to go after this

  Conclusion and Where to Go After This Congratulations on completing your Python learning journey! You've covered a wide array of topics, from the basics of syntax and data types to advanced concepts like multithreading, multiprocessing, and decorators. But learning doesn't stop here. Python is a versatile language with many specialized fields where you can apply your skills. Here are some potential paths you can explore next: Machine Learning Machine Learning (ML) is one of the most exciting fields you can dive into. Python's libraries like TensorFlow, Keras, scikit-learn, and PyTorch make it an ideal language for building ML models. You'll learn about supervised and unsupervised learning, deep learning, neural networks, and more. Start with the basics of linear regression and classification, then move on to more complex models like convolutional neural networks (CNNs) and recurrent neural networks (RNNs). Data Structures and Algorithms (DSA)...
