2. The second line initializes a dictionary of lists, with two keys (Name and Age) and four values for each key. 3. The third line creates a DataFrame object from the data dictionary created in the previous step. 4. The fourth line creates a new column called ‘Combined’ by concatenat...
While you could choose any way to distinguish these files, here are two of the easiest ways: Create a unique prefix on all of the files that you want to import at once. Create a separate folder in your working directory and only include those files in that folder....
have multiple (two or more) indexlevelson an axis. Another way of thinking about it is that it provides a way for you to work with higher dimensional data in a lower dimensional form. Let’s start with a simple example: create a Series with a list of lists (or arrays) as the index...
This setup ensures the script is self-sufficient in managing its required resources. File loading: The script lists all files in the input directory and begins processing each one that matches the expected file extension (defined in step 1 as .raw). For each valid input file, the code: ...
numbers) that are unique in that set. For example, if you were to do a set operation on the array[1,1,2,3]Ruby will filter out that second 1, even though 1 may be in the resulting set. So be aware that these set operations are different than list operations. Sets and lists are...
