Recall Loops

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.

Завдання

Follow the algorithm:

Create a for loop that iterates through the 'job_title' column in the df.
Within the for loop, implement the if statement that checks if i is equal to 'Data Scientist'.
Within the if statement, increase the count variable by 1.

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 pandas offer you.
