How do you declare a variable in Python?

• value = variable_name

• variable_name : value

• variable == value

• variable_name = value

What is the difference between '==' and 'is' in Python?

• The '==' operator compares values, while the 'is' operator compares identities.

• The '==' operator compares references, while the 'is' operator compares values.

• The '==' operator compares identities, while the 'is' operator compares values.

• The '==' operator is used for assignment, while the 'is' operator is used for comparison.

Explain the 'if' statement in Python with an example.

• Example: x = 0 if x > 5 else 10

• Example: x = 10 if x > 5 else 0

• Example: x = 10 if x < 5 else 0

• Example: x = 5 if x > 10 else 0

What is the purpose of 'elif' in Python?

• It allows for multiple conditional branches to be evaluated in sequence.

• It is a keyword used to create a loop in Python.

Explain the concept of 'recursion' in Python.

• Recursion in Python is a programming technique where a function calls a built-in Python module in its own definition.

• Recursion in Python is a programming technique where a function calls itself in a loop.

• Recursion in Python is a programming technique where a function calls another function in its own definition.

• Recursion in Python is a programming technique where a function calls itself in its own definition.

What is the difference between 'global' and 'local' variables in Python?

• Global variables are defined using 'let' keyword, while local variables use 'var'.

• Global variables are accessible throughout the entire program, while local variables are only accessible within the function where they are defined.

• Global variables are only accessible within the function where they are defined.

• Local variables are accessible throughout the entire program.

How do you pass arguments to a function in Python?
