timberlake | Timberlake is a Job Tracker for Hadoop

I am learning how to parse through different files (xml, json, csv) and grabbing specific values in Python. However, I do not know how to go about writing code to find things such as which movie summary has the most characters or the total number of movies. I was wondering if somebody could please point me in the right direction or if there is a video that helps with grabbing info from a json file.

Here's the json file:

I have created a project in Java called Music and there is a file called music.txt within the NetbeansProjects, I would like to sort all the data, for example, the singer, song name, year, duration in minutes, and genre into the Music project.

I have used collections.sort, however for that I have copied and pasted all the data and wrote:

I have a dataset with discrets distances and Months (The months are interpolated as 1, 1.1, 1.2, etc.) and a z variable. Months are numeric, not dates here. I interpolate using a loess function and want to plot it using ggplot, geom_tile.

I looked all the similar questions on the web but nothing turned useful to me. I have a string which I receive from server i.e.

'Justin Timberlake - Can't Stop the Feeling'

It has single quotes in it. Before passing it to NSPredicates, it gets changed to

"text = \'\'Justin Timberlake - Can\'t Stop the Feeling\'\'"

I tried everything, i.e. replacing single quote with \' etc. But nothing helped. What else should I do.

I am trying to create a string of the artist's names from the artists array shown below (i.e. "Taylor Swift, Rihanna, Justin Timberlake"), but the artist_obj is undefined and I get the error "TypeError: Cannot read property 'name' of undefined". How do I fix this?
