Pandas Styling: Exercises, Practice, Solution

[An editor is available at the bottom of the page to write and execute the scripts.]

Styling: This is a new feature and still under development. The styling is accomplished using CSS. You can write "style functions" that take scalars, DataFrames or Series, and return like-indexed DataFrames or Series with CSS "attribute: value" pairs for the values.

Python: Tips of the Day

For-else construct useful when searched for something and find it:

# For example assume that I need to search through a list and process each item until a flag item is found and 
# then stop processing. If the flag item is missing then an exception needs to be raised.

for i in mylist:
    if i == theflag:
        break
    process(i)
else:
    raise ValueError("List argument missing terminal flag.")
