Python is a high-level, interpreted programming language known for its simplicity and readability.

• Python is dynamically typed and garbage-collected.

• It supports multiple programming paradigms like procedural, object-oriented, and functional programming.

• Python has a large standard library and a thriving community of developers.

• Example: print('Hello, World!')

The # symbol is used to add comments in Python code, which are ignored by the interpreter.

• Comments are used to explain the code and make it more readable for other developers.

• Comments start with the # symbol and continue until the end of the line.

• Comments can also be used to temporarily disable code without deleting it.

• Example: # This is a comment in Python code.

Docstring in Python is a string literal that occurs as the first statement in a module, function, class, or method definition.

• Docstrings are used to document code and provide information about the purpose and usage of the code.

• They are enclosed in triple quotes (either single or double) and are accessible through the __doc__ attribute.

• break is used to exit a loop prematurely

• continue is used to skip the current iteration and continue to the next one

• pass is a null operation, used when a statement is required syntactically but you do not want any command or code to execute

Remove the N-th node from the end of a linked list efficiently using two-pointer technique.

• Use two pointers: 'fast' and 'slow'.

• Move 'fast' pointer N steps ahead.

• Then, move both pointers until 'fast' reaches the end.

• The 'slow' pointer will be at the node before the N-th from end.

• Adjust pointers to remove the target node.

This task involves removing duplicates from a sorted list, ensuring each element appears only once.

• Iterate through the list: Use a loop to traverse the sorted list and compare each element with the next one.

• Use a new index: Maintain a separate index for the unique elements, copying over only the distinct values.

• Example: For a sorted list [1, 1, 2, 3, 3], the result should be [1, 2, 3].

• In-place modification: If required...read more
