Python syntax

Python is a popular programming language with a clear and concise syntax. Here are some of the basic syntax rules for Python:

Comments: Use the '#' symbol to add comments in your code. Everything after the '#' symbol is ignored by the interpreter.

Code

# This is a comment

Indentation: Python uses indentation to define code blocks. Use four spaces or a tab to indent code within a block.

Code

if x > 5: print("x is greater than 5") else: print("x is less than or equal to 5")

Variables: Python does not require you to specify the data type of a variable. You can assign any value to a variable and Python will determine the data type automatically.

Code

x = 5 y = "Hello, world!"

Operators: Python supports a wide range of operators, including arithmetic, comparison, logical, and assignment operators.

Code

# Arithmetic operators

x + y

x - y

x * y

x / y

x % y

# Comparison operators

x == y

x != y

x > y

x < y

x >= y

x <= y

# Logical operators

x and y

x or y

not x

# Assignment operators

x = y

x += y

x -= y

x *= y

x /= y

Functions: You can define functions in Python using the 'def' keyword.

code

def my_function(x, y): z = x + y return z result = my_function(3, 4) print(result)

These are just a few examples of the syntax rules in Python. Python has a rich set of features and capabilities that make it a versatile and powerful programming language.
