In the chapters to come, we will delve(钻研) more deeply into data analysis and manipulation topics using pandas. This book is not inteded to serve as exhausitive(详尽的) documentation for the pandas library; instead, we'll focus on the most important features, leaving the less common(i....
the.head()part first selects the first 5 rows of our data set and then the[['country', 'user_id']]part takes only thecountryand theuser_idcolumns for this first 5 rows. Could you get the same result with a different chain of functions? Of course, you can: ...
