Python Syntax

Python is a high-level programming language known for its simplicity and readability. Here are some fundamental aspects of Python syntax:

Statements and Indentation:

• Python uses indentation to define blocks of code instead of brackets or braces like other programming languages. It is recommended to use 4 spaces for indentation.
• Statements in Python are typically written on separate lines.

Example:

if x > 7:
    print("x is greater than 7")

Comments:

• Comments are used to add explanatory notes to code and are ignored by the Python interpreter.
• Single-line comments start with the # symbol, while multi-line comments are enclosed between triple quotes (''' or """).

Example:

# This is a single-line comment
'''
This is a
multi-line comment
'''

Variables and Data Types:

• Variables are used to store values. In Python, you can assign a value to a variable using the = operator.
• Python is dynamically typed, meaning you don’t need to declare the data type explicitly. It is inferred based on the assigned value.
• Common data types in Python include integers (int), floating-point numbers (float), strings (str), booleans (bool), and more.

Example:

x = 10
name = "John"
is_valid = True

Operators:

• Python supports various operators, such as arithmetic operators (+, -, *, /, %, **), comparison operators (==, !=, >, <, >=, <=), logical operators (and, or, not), assignment operators (=, +=, -=, *=, /=, %=), and more.

Example:

x = 10 + 5
y = (x > 5) and (x < 20)

Conditional Statements:

• Python has if, elif, and else statements for conditional execution.
• Indentation is crucial to define the block of code executed under each condition.

Example:

if x > 10:
    print("x is greater than 10")
elif x == 10:
    print("x is equal to 10")
else:
    print("x is less than 10")

Loops:

• Python provides for and while loops for iterative execution.
• Again, indentation is essential to define the block of code inside the loop.

Example:

for i in range(5):
    print(i)
while x < 10:
    print(x)
    x += 1

These are just some of the basic syntax elements of Python. Python offers a vast set of libraries and advanced features to accomplish various programming tasks.
