PandasdrillPull numbers out of codes
A pandas exercise from Pandasdrill. Solve it with a Python editor in your browser running real pandas, and it is checked the moment you submit.
The task
Each code looks like ORD-2024-0153. Extract the final group of digits as an integer (so 0153 becomes 153) and return it as a Series.
What this exercise teaches
str.extract with one capture group returns a DataFrame whose column 0 holds the match. Anchoring with $ picks the last digits rather than the year, and astype(int) turns "0153" into 153.
A hint if you get stuck
A regular expression like (\d+)$ captures the digits at the end of the string. str.extract returns a DataFrame, one column per group.
