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

Measure the execution time of small bits of Python code with the "timeit" module.

Example:

import timeit
print(timeit.timeit('"-".join(str(n) for n in range(100))',
number=100000))

print(timeit.timeit('"-".join([str(n) for n in range(100)])',
number=100000))

print(timeit.timeit('"-".join(map(str, range(100)))',
number=100000))

Output:
