Syntax (Rules and Structure)

Question 1

What is Syntax in python

Answer 1

Syntax is a fixed set of rules that defines the correct structure, order, and format of Python code.
So that Python interpreter can parse and execute code without errors.

Question 2

Types of Syntax

Answer 2

• Indentation
• Variable Names and Assignment
• Operators and Expressions
• Function Definition and Calls

Question 3

Indentation

Answer 3

Unlike many other programming languages, Python uses indentation to define code blocks (loops, conditionals, functions, etc.), not braces {}.

def example_function():
for i in range(5):
print(i) # Indented to show it’s part of the loop

def example_function():
for i in range(5): # Missing indentation
print(i)
# Results in: IndentationError: expected an indented block

Question 4

Variable Names and Assignment

Answer 4

Variable names must follow specific rules (e.g., cannot start with numbers or use special characters like @, $).

my_variable = 10

1st_variable = 10 # SyntaxError: invalid syntax

Question 5

Operators and Expressions

Answer 5

Python has strict rules for how operators and expressions should be written.

result = 5 + 3

result = 5 + # SyntaxError: invalid syntax

Question 6

Function Definition and Calls

Answer 6

Functions must have parentheses and colons in their definitions.

def greet(name):
return f”Hello, {name}!”

def greet name: # SyntaxError: invalid syntax (missing parentheses)
return f”Hello, {name}!”
