Imagine that you want to count how many 'Data Scientist' jobs are in the dataset. You are already familiar with the loops and if/else statements. Try it.

Follow the algorithm:
- Create a
forloop that iterates through the'job_title'column in thedf. - Within the
forloop, implement theifstatement that checks ifiis equal to'Data Scientist'. - Within the
ifstatement, increase thecountvariable by 1.
Soluzione
In this chapter, you count values in a straightforward but irrational way. Imagine that you have thousands of rows in the dataset; such a loop may take even an hour to process, depending on the dataset's size and the computer's power. Thus, in the next section, you will learn how to do the same thing but in a way that
pandasoffer you.
