kandi X-RAY | LaPy Summary
LaPy is a package to compute spectral features (Laplace-Beltrami operator) on tetrahedral and triangle meshes. It is written purely in python 3 without sacrificing speed as almost all loops are vectorized, drawing upon efficient and sparse mesh data structures. It is a basically a port of the C++ ShapeDNA project with extended differential geometry capabilities.

QUESTION
Im using a csv file that has the lap number on a column, where each row contain data about that lap (last number is the lap), like this: value1, value2, 1 value3, value4, 1 ... valueN, valuex, 99
I have a subset of this data, so i have a range from lapX to lapY, and i want to rearrange it, where lapX is 1 and each time a new lap appears add 1 to the actual lap. I write this code that do what i want:
...ANSWER
Answered 2021-Jul-07 at 20:46Based on the expected dataframe, it looks like you just want to re-number the laps incrementally, even if they are not consecutive laps. So 5, 6, 9 becomes 1, 2, 3.
For that, take the unique values of Lap
and sort them. Then zip it with a itertools.count()
which just counts up. Make a dictionary from that and then map the old Lap values to new Lap values:

Install LaPy
You can use LaPy like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
