Python Overview and Benefits

Ease of use and readability, which facilitate faster development.

Guido Van Rossum created Python in 1991.

An interpreted language executes code line by line using an interpreter. An advantage is easier debugging since errors are identified during execution.

<p>Compiled languages run directly on hardware since they are already converted into machine code, leading to faster execution.</p> Signup and view all the answers

<p>Interpreted languages can lead to runtime errors if types are misused, as type consistency is harder to enforce.</p> Signup and view all the answers

<p>C is a compiled language that results in platform-specific machine code and provides fast execution as well as error checking during compilation.</p> Signup and view all the answers

<p>Compiled languages detect errors during the compilation process, which prevents the program from running until it is error-free.</p> Signup and view all the answers

<p>Compiled machine code is tailored for the specific operating system and hardware it was compiled for, making it incompatible with others.</p> Signup and view all the answers

<p>Compiled languages typically offer better performance due to optimization for speed and more effective error checking during compilation.</p> Signup and view all the answers

<p>Compiled languages have a slower development cycle due to the compilation step that adds extra time to the process.</p> Signup and view all the answers

<p>Compiled languages typically have better performance as they are translated to machine code before running, while interpreted languages are slower due to line-by-line execution.</p> Signup and view all the answers

<p>Debugging in compiled languages is harder because errors are caught during compilation, often making it difficult to trace their origins.</p> Signup and view all the answers

<p>A statically typed language requires the programmer to specify the data type of a variable at the time of declaration.</p> Signup and view all the answers

<p>A shallow copy shares references to nested objects, while a deep copy creates independent copies of all nested objects.</p> Signup and view all the answers

<p>You can create a shallow copy using the <code>copy()</code> method or the <code>copy.copy()</code> function from the copy module.</p> Signup and view all the answers

<p>Modifying a nested object in a shallow copy will affect the original object since they share the same references.</p> Signup and view all the answers

<p>You would use the <code>copy.deepcopy()</code> function from the copy module to create a deep copy.</p> Signup and view all the answers

<p>The output would be [[99, 2, 3], [4, 5, 6]], as the nested objects are shared between the original and shallow copy.</p> Signup and view all the answers

<p>You would choose a deep copy to ensure that all objects are independent and changes to the copy do not affect the original.</p> Signup and view all the answers

<p>A shallow copy creates a new list, but the inner lists are references to the same inner lists in the original.</p> Signup and view all the answers

<p>The Timsort algorithm is used by both the sort() and sorted() functions in Python.</p> Signup and view all the answers

<p>list.sort() sorts the list in-place, modifying the original, while sorted() returns a new sorted list without altering the original.</p> Signup and view all the answers

<p>A shallow copy is preferred when the nested objects are large or immutable and you want to avoid duplicating them for performance.</p> Signup and view all the answers

<p>The list.sort() method outputs the sorted original list, while sorted() outputs a new sorted list, leaving the original unchanged.</p> Signup and view all the answers
