Python syntax defines a set of rules that are used to create a Python Program. Python syntax also comprises a set of rules and elements that collectively make up the Python Syntax. In this article, we will explore what are different components in syntax.
Table of contents:
Python code is composed of both physical and logical lines.
Example
Variable = 6
NOTE: A logical line that only contains spaces, comments, or tabs are called blank lines and they are ignored by the interpreter.

Python Multiline StatementsIn Python, a new line represents the beginning of a new statement. However, Python allows you to break a statement over many lines or combine numerous statements into a single logical line.
1. Explicit Line JoiningA backslash (\) is used to split a statement across multiple lines.
Example:
We can also use explicit line joining to join two or more physical lines into a logical line, using backslash.
2. Implicit Line JoiningStatements inside parentheses (), brackets [], or curly braces {} can be broken into multiple lines without using a backslash.
Example:
3. Multiple Statements on a Single LinePython allows multiple statements on a single line using a semicolon (;), but this is not recommended as it reduces code readability.
Example:
Whitespaces and IndentationUnlike most programming languages, Python enforces indentation to define blocks of code. According to PEP 8 (Python’s official style guide), the recommended indentation size is four spaces per level.
Incorrect indentation leads to errors:

IdentifiersIdentifiers in Python are nothing but user-defined names to represent programmable entities like (Python Variables, Python Functions, Python Class, Python Modules), or any other objects. But, there are a few rules that we need to follow while defining an identifier. They are:
Python has a set of reserved words (keywords) that cannot be used as identifiers. These words have predefined meanings and are case-sensitive.
False class finally is return None continue for lambda try True def from non-local while and del global not with as el if or yield assert else import pass break except in raise Python QuotationsPython supports both single (‘) and double (“) quotes for defining strings. The type of quote used at the beginning must match the one used at the end.
Example:
In this guide, we explored the fundamental elements of Python syntax, including line structure, indentation, reserved words, and quotation rules. Understanding these basics will help you write clean, efficient, and error-free Python code. If you want to learn more about the same, please check out our Comprehensive Python Course.
