Using last has the opposite effect: the first row is dropped. keep, on the other hand, will drop all duplicates. If two rows are the same then both will be dropped. Watch what happens to temp_df: temp_df = movies_df.append(movies_df) # make a new copy temp_df.drop_duplicates(...
it prints the value of the local variable x (i.e., 5). However, when the function is finished and x is printed again outside of the function, it prints the value of the global variable x (i.e., 10).

We often want to work with subsets of aDataFrameobject. There are different ways to accomplish this including: using labels (column headings), numeric ranges, or specific x,y index locations. Selecting data using Labels (Column Headings)
This text uses the term collection instead of iterable. For rationale see Collection. <int> = len(<list>) # Returns number of items. Also works on dict, set and string. <int> = <list>.count(<el>) # Returns number of occurrences. Also `if <el> in <coll>: ...`. <int> = <...
Len() should return the number of items. This cheatsheet actually means '<iterable>' when it uses '<collection>'. I chose not to use the name 'iterable' because it sounds scarier and more vague than 'collection'. The main drawback of this decision is that the reader could think a ...
You should use this version in situations where say a user can click a button and that causes a panel to slide out, and you want to reverse that same animation to begin sliding in the opposite direction. Parameters: animation (WidgetAnimation)– The animation to play playback_speed (float)...
