List is mutable, tuple is immutable in Python.

• List is mutable, meaning its elements can be changed after creation.

• Tuple is immutable, meaning its elements cannot be changed after creation.

• List is defined using square brackets [], tuple using parentheses ().

• Example: list_example = [1, 2, 3], tuple_example = (4, 5, 6)

A number is even if it is divisible by 2, otherwise it is odd.

• Use the modulo operator (%) to check if a number is divisible by 2.

• If number % 2 == 0, then the number is even.

• For example, 4 % 2 == 0, so 4 is even; 5 % 2 != 0, so 5 is odd.

A simple program to determine if a number is even or odd.

• Use the modulo operator (%) to check if the number divided by 2 leaves a remainder

• If the remainder is 0, the number is even. Otherwise, it is odd

• Example: num = 6, 6 % 2 = 0 (even); num = 7, 7 % 2 = 1 (odd)

Python generator is a function that returns an iterator object which can be iterated over.

• Generators are created using a function with 'yield' statement instead of 'return'.

• They allow you to iterate over a sequence of items without creating the entire sequence in memory at once.

• Generators are memory efficient and can be used to generate an infinite sequence of items.

• Example: def my_generator(): for i in range(5): yield i

• Example: gen = my_generator() print(next(gen)) # Output:...read more

A generator function in Python yields values one at a time, allowing for lazy evaluation.

• Use the 'yield' keyword in a function to return values lazily

• Generators are memory efficient as they only compute values as needed

• Example: def lazy_generator(): for i in range(5): yield i

• Call the generator function using next() to get the next value
