Python Syntax and Basic Output

Python is a high-level, interpreted language known for its simplicity and readability. Understanding syntax and output is essential for all Python programs.

1. Python Syntax Rules

Python uses indentation instead of braces {} to define code blocks.
Statements end automatically at newline; no semicolons needed (optional).
Python is case-sensitive: Variable and variable are different.
Comments start with # for single-line comments, or ''' ''' / """ """ for multi-line comments.

# Single-line comment
"""
Multi-line comment
explaining code
"""

2. Python Statements

Single-line statement:

x = 5
print(x)

Multiple statements on a single line (use ;):

a = 1; b = 2; c = a + b
print(c)

3. Indentation

Indentation is mandatory for defining blocks like loops, conditionals, and functions.

if True:
    print("This is indented correctly")
# Wrong indentation will cause IndentationError

4. Python Output Using `print()`

print() displays information to the console.

# Simple output
print("Hello, Python!")

# Printing variables
name = "Alice"
age = 25
print(name, age)

# Formatted output (f-strings)
print(f"My name is {name} and I am {age} years old.")

# Using separator and end
print("Python", "is", "fun", sep="-", end="!\n")
# Output: Python-is-fun!

5. Escape Characters

Escape Sequence	Meaning
`\n`	New line
`\t`	Tab
`\\`	Backslash
`\'`	Single quote
`\"`	Double quote

print("Hello\nPython")  # Hello (new line) Python
print("Column1\tColumn2")  # Tab space

6. Key Points

Python emphasizes readability and simplicity.
Indentation defines code blocks.
print() is used for basic output, supports variables, formatting, and escape sequences.
Python statements can span multiple lines using backslash \ if needed.
Proper syntax is crucial to avoid runtime errors.
