Python Syntax

Python is designed by its creators to be human readable and easy for programmers to write. Python is known for its simple and readable syntax.

Here is an example of a simple Python program that prints “Hello, World!” to the console:

# This is a comment in Python
# The print function is used to print output to the console
print("Hello, World!")


Indentation is used to indicate blocks of code, instead of curly braces which are used in many other programming languages. This helps to make Python code easy to read and understand, as indentation is used consistently throughout the code.

Dynamic Typing

In Python, variables do not have to be declared before they are used, and they do not have a fixed type. This is called “dynamic typing”. For example:

x = 10  # x is an integer
x = "Hello"  # now x is a string

Python also has a wide range of built-in data types, including integers, floating-point numbers, complex numbers, strings, lists, tuples, and dictionaries. We will see them in the coming articles.

I hope this helps to give you a basic understanding of Python syntax!

Syntax Error

In Python, a syntax error is an error in the source code of a program that prevents the interpreter from parsing it. Syntax errors are usually easy to fix, as they are typically caused by a typo or a missing character in the code.

Here is an example of a syntax error in Python:

def greeting(name):
  print("Hello" + name


In this example, the interpreter will raise a syntax error because there is a missing closing parenthesis on the print statement. To fix the error, you would need to add the missing parenthesis:

def greeting(name):
  print("Hello" + name)


There are several types of syntax errors that can occur in Python. Here are a few common ones:

  • Incorrect indentation: In Python, If a block of code is not properly indented, the interpreter will raise an IndentationError.
  • Missing or extra characters: Syntax errors can also occur when there are missing or extra characters in the code, such as a missing colon at the end of a for loop, or an extra comma in a list.
  • Mismatched parentheses or brackets: Syntax errors can also occur if there are mismatched parentheses or brackets in the code. For example, if you forget to close a parenthesis or square bracket, the interpreter will raise a SyntaxError.
  • Invalid keywords or variables: Syntax errors can also occur if you try to use a Python keyword as a variable name, or if you try to use an undefined variable.

PEP 8 – Style Guide for Python Code

A style guide is a set of guidelines for writing and formatting code in a specific programming language. In the Python community, there is a widely recognized style guide called “PEP 8 – Style Guide for Python Code,” which provides a set of rules for how to write and format Python code. You must go through once from whole doc Here

Some of the guidelines in PEP 8 include:

  • Use 4 spaces for indentation, rather than tabs
  • Limit lines of code to a maximum of 79 characters
  • Use blank lines to separate functions and class definitions
  • Use single quotes for string literals, unless you need to use a string literal that contains a single quote, in which case you should use double quotes

Do not use spaces around the = operator when assigning values to variables

Adhering to a style guide can help make your code more readable and easier to understand for others who may be reading or working with your code. It can also help you write more consistent code and avoid common formatting mistakes.
