Lists are mutable while tuples are immutable in Python.

• Lists use square brackets [] while tuples use parentheses ().

• Elements in a list can be added, removed, or modified while tuples cannot be modified.

• Lists are used for collections of homogeneous items while tuples are used for heterogeneous items.

• Lists are slower than tuples in terms of performance.

• Example: my_list = [1, 2, 3] and my_tuple = (4, 'hello', True)

PEP 8 is a style guide for Python code.

• PEP stands for Python Enhancement Proposal.

• PEP 8 provides guidelines for writing readable and maintainable Python code.

• It covers topics such as naming conventions, code layout, and programming practices.

• Examples include using snake_case for variable names and indenting with four spaces.

• Adhering to PEP 8 can make code more consistent and easier to understand for other developers.

Namespace is a way to organize code and avoid naming conflicts in Python.

• Namespaces are implemented as dictionaries.

• Python uses namespaces to support modularity and avoid naming conflicts.

• Namespaces can be nested within other namespaces.

• The global namespace is the namespace that is visible throughout the entire program.

• The local namespace is the namespace that is visible only within a particular function or code block.

Lambda expression is a concise way to represent anonymous functions in programming languages.

• Lambda expressions are used to create functions without a name.

• They are often used in functional programming languages.

• Lambda expressions can be used to pass functions as arguments to other functions.

• They can also be used to create closures, which are functions that capture variables from their surrounding environment.

• Lambda ex...read more

Pickling is the process of converting a Python object into a byte stream, while unpickling is the reverse process.

• Pickling is used to store Python objects in a file or transfer them over a network.

• The pickle module in Python is used for pickling and unpickling.

• The pickled file can be opened in any Python environment and the object can be retrieved.

• Unpickling can also be used to create a deep copy of an object.

• Security ...read more
