The primary benefit of using tuples as keys in dictionaries is that tuples are immutable, while lists are not. This immutability ensures that the keys won't change, making tuples suitable for use as dictionary keys. Lists can't be used as keys because they can change.

The import statement is used to dynamically load a module into the current Python namespace. It allows you to access functions, classes, and variables defined in the imported module. This dynamic loading is crucial for code modularity and reusability, enabling you to use code from different modules in your Python programs.

To overload the less than (<) operator for a class, you define the __lt__ (less than) method in your class. This method is called when the "<" operator is used with objects of the class.

The primary difference is that class attributes are shared among all instances of a class, whereas instance attributes are specific to each instance. This affects how data is stored and accessed in Python classes.

A function defined inside another function in Python is called an 'Inner function' or 'Nested function.' They have access to the variables of the enclosing function.

In Python, the 'if' keyword is used to check a condition. It allows you to execute a block of code if the condition is true.

The 'readlines()' method reads the entire file into memory, which can be inefficient for large files, as it can lead to memory consumption issues. It's better to use methods like 'readline()' or iterate over the file to process it line by line.

The 'continue' statement is used to skip the remaining code in the current iteration of a loop and move to the next iteration without exiting the loop. So, you would use 'Continue.'

Python is available by default on Windows, macOS, and Linux. However, it is not available by default on Android operating systems.

The 'continue' keyword is used to stop the execution of the current iteration in a loop and proceed to the next iteration. It allows you to skip specific iterations.
