Fundamentals: step by step to learn Python

Python is one of the most popular programming languages out there, and it's a great place to start for beginners. If you're just getting started in coding, this blog post is for you! We'll go over the basic fundamentals of Python and provide some helpful tips for mastering the language. Let's get coding!

Introduction to Python Programming Language

Python is a powerful, modern, and industry-demanding coding language. It was created by Guido van Rossum in 1991 and is used for web development, software development, scripting, and more. In this guide, we'll go through the basics of Python programming language to get you started on the journey to becoming a Python power user.

First, let's take a look at what Python can do. Python can be used to store and manipulate data, automate repetitive tasks, create complex algorithms for data analysis, and more. It's also used for scripting purposes in many programming languages and platforms.

Now that you know what Python can do, let's learn about its syntax and structure. Python's syntax is relatively simple compared to other programming languages - it uses white-space indentation to denote code blocks and statements instead of brackets or keywords. This makes it easier for beginners to learn Python quickly since the code is more readable.

The next step is to learn how to use the Python standard library. The standard library contains pre-written code that can be used to quickly build applications without having to write all of the code from scratch. The standard library includes modules such as math, time, sys, and os which contain functions that can be used in your code.

Once you understand the syntax and structure of Python and know how to use the standard library, you can start learning about data science with it. Data science is an important field which involves collecting and analyzing data in order to gain insights into a certain problem or topic. With Python, you can use the numerous libraries available such as NumPy, Pandas, Scikit-Learn, TensorFlow and more to analyze data quickly and accurately.

Next up is learning about the different concepts in Python programming through online resources such as W3Schools or other tutorials.

Learn Python Basics

In this section, we’ll look at the basics of Python programming language and learn how to write code in it. You’ll learn about data types such as strings, integers, booleans and floats, as well as data structures like lists, dictionaries and tuples. We’ll also look at console output, which is the way of displaying information on the screen using print() statements.

To get started writing code in Python, all you need is a text editor or an interactive Python environment like IDLE or Jupyter Notebook. When writing your code in a text editor, make sure to save your work using the .py extension (for example:

Once you have your text editor of choice set up, it’s time to start writing code! To start off, try writing a simple ‘hello world’ program in Python:

print(‘Hello World!’)

Understand Python Syntax

Python is a powerful and versatile programming language, and its syntax is the set of rules that define how code is written and structured. Understanding Python syntax is essential if you want to learn the language and start writing code. In this section, we’ll explore some of the basic syntax of Python so you can get started with coding.

First, let's look at the structure of a Python script. A Python script is composed of lines of code that are executed in order. Each line of code must end with a semicolon (;), and each line must be indented correctly to indicate which lines should be executed together. The indentation helps keep the code readable and organized.

Next, let's look at the different types of data that can be used in Python. There are two main types: strings (text) and numbers (integers and floats). Strings are written with single or double quotes around them, while numbers are written without any quotes.

print('strings example');

//integers and floats

Now that we understand the structure of a script and the different types of data, we can look at some common Python commands. The print command is used to display text or numbers on the screen. For example, if you type print("Hello") into a script, it will display "Hello" on the screen. Other commands include input() to get text or number input from a user, if-else statements to control program flow, and for loops to execute multiple lines of code multiple times.

x = input('Enter your name:')
print('Hello, ' + x) 

//if-else statements
a = 200
b = 33
if b > a:
  print("b is greater than a")
elif a == b:
  print("a and b are equal")
  print("a is greater than b")

//for loops
fruits = ["apple", "banana", "cherry"]
for x in fruits:
  if x == "banana":

Finally, let's look at how variables work in Python. Variables are used to store data in a program, so they can be accessed later. To create a variable, simply assign a value to it by typing its name followed by an equal sign (=) followed by its value. For example, if you type  :

my_variable = 10

it will create a variable named my_variable with a value of 10 assigned to it.

Testing and debugging your code is an important part of the development process. It’s the only way to make sure your code works as expected, and that you’ve successfully completed your project.

When it comes to debugging your Python code, there are two main approaches you can take. First, you can use a Python debugger such as pdb or IPython. These tools allow you to step through your code line by line to identify any errors or issues.

The second approach is to use print statements in your code to output the values of variables. This is useful for quickly checking the state of your program and identifying any errors that might be occurring.

Whichever approach you choose, it’s important to make sure you thoroughly test and debug your code before calling it complete. Doing so will help ensure that your project runs as expected and that you don’t experience any unexpected issues down the line.

Repeat until all the tasks are completed and the project is finished

Now that you’ve broken down the project into smaller tasks, researched any concepts you didn’t understand and written code for each task, it’s time to test and debug any errors in your code. It’s important to take your time and go through the code carefully. Even though it may seem tedious, it’s worth it in the long run.

Start by testing the code for each task individually to make sure everything works as expected. Debugging usually involves making corrections to the code after it has been tested. This could involve changing syntax, adding or removing lines of code, or changing variable values.

Once all the tasks have been tested and debugged, you can combine them all together to make sure they work together properly. This is the final step in completing the project. After checking the entire program, you should be able to confidently move on to your next Python project or exercise.
