Here are 25 questions related to the subtopic of "indexing and slicing" using lists in Python, formatted according to the PCEP-30-0x examination style. Question 1: What will the following code output? my_list = [10, 20, 30, 40, 50] print(my_list[2]) 10 20 30 40 ▼ Question 2: ...
In this video, you’ll practice list indexing and slicing. The elements of a list can be accessed by an index. To do that, you name the list, and then inside of a pair of square brackets you use an index number, like what I’m showing right here. That…

Python Copy word[-2] # Second-to-last character.The output is:Output Copy 'o' SlicesPython supports both indexing, which extracts individual characters from a string, and slicing, which extracts a substring (or slice). To slice, you indicate a range in the format start:end. The start...
In this example, we accessed theNameand theCitycolumns ofdfusing the[]operator. It returned a DataFrame containing the values fromNameandCityofdf. The[]operator, however, provides limited functionality. Even basic operations like selecting rows, slicing DataFrames and selecting individual elements are...
TypeError: 'builtin_function_or_method' object has no attribute '__getitem__' when using partition and rpartition, Splitting Strings with Python Built-in Function Results in Exception, Unfamiliarity with 'AttributeError: __getitem__', Error in Python due
Accessing characters, whether they are single or multiple, is an essential skill for working with strings in any programming language. In Python, we do this by indexing and slicing the string. In this hands-on lab, we'll go through writing some code to demonstrate that we understand how to...
Learn the key differences between indexing and slicing in Python, including how to use them effectively for data manipulation.
In this tutorial, we will cover Indexing and Slicing in the Numpy Library of Python.To access and modify the contents of ndarray object in Numpy Library indexing or slicing can be done just like the Python's in-built container object.We...
