Assignment - 3 - 4th question

assignment 3 (4th question) - In this question first using sort_values for ascending order of population. After that for hightest 10 country population I sould use tail instead of head because head will give me result of 10 least population. countries . . Am I right?

That would give you the 10 countries with the highest population. However, the dataframe would still be in ascending order and not descending order. That means the country with the highest population would be the 10th row instead of the first row.

You can pass a parameter to sort_values to sort in descending order and then use head to get the desired result.

You have a typo in variable name, so the automatic assignment evaluation can’t find the answer. Fix the name.

Hello @prathamtidke55, as @Sebgolos mentioned you have a typo in variable name. Just change the name from most_populus_df to most_populous_df. We are not allowed to change the variable name in any assignment.
