.loc Function

Pandas allows you to set specific conditions on the dataset without an if/else statement and loops. Look at the syntax:

DataFrame.loc[DataFrame['job_title'] == 'Data Scientist'].count()

So inside the .loc[] function, you just put the condition you need. Here you compare if 'job_title' is equal to 'Data Scientist'.

It compares each value of 'job_title' to the 'Data Scientist' string.

The ways of creating such conditions are the same as for if statements; you can use >, <, >=, =<, == with the same meaning.
