BLU04 - Advanced data wrangling

What is in this BLU?

This is the first BLU in the Data Wrangling specialization. In this specialization you'll learn how to get data from multiple data sources and how to transform raw data into clean enough data so that you can begin your data science workflow.

In this BLU, we'll start by learning some Jupyter notebooks magics, that can be very useful. Then, we'll learn about file formats and how to read them efficiently into pandas DataFrames. Finally, we'll practice some data cleaning, using string methods and other tools.

Exercises Notebook Q1

When assigning a value to variable num_lines, just copy and paste the number of lines that you found with the ! command.
No need to apply any logic here.

Remember that nbgrader may not be running the same operative system as you are, and thus it won't understand the shell command you're running locally to determine the number of lines.

Minor language mariquices

A sintaxe do nome do ficheiro, do nome do diretório ou da etiqueta do volume é incorreta.

Am I the only one to have this issue in the learning notebooks? Trying to run as admnistrator won't solve it.
