pivot() is used for pivoting without aggregation. Therefor, it can’t deal with duplicate values for one index/column pair. pivot_table is a generalization of pivot that can handle duplicate values for one pivoted index/column pair. Specifically, you can give pivot_table a list of aggregation functions using keyword argument aggfunc.

As column names or headers can be easily attributed to the data read from a fixed width file, it is easier for a programmer to understand the filter conditions applied If the data in the text file is comma separated and squeezed rather than a fixed width file, it is easier in python to adapt to such a layout change. i.e., read statement alone ...

After we had collected traffic data for Interstate 5 North over the period of July 1, 2018 through November 30, 2018, we began implementing Python modules to parse the raw data files and load them into a SQLite3 database. We accomplished this by creating one Python script to parse and load each traffic data type: speed, flow, and incidents.

Compute row and column sums and means for numeric arrays. colSums, rowSums, colMeans, rowMeans. These functions are equivalent to use of apply with FUN = mean or FUN = sum with appropriate margins, but are a lot faster. As they are written for speed, they blur over some of the subtleties of NaN and NA.

In Section 7.2, we can crawl a huge number of WARC files. However, ArchiveSpark needs both WARC files and CDX files as the input. Therefore, we made use of CDX-Writer, a Python script to create CDX index files of WARC data, to generate the CDX files. Please notice that CDX-Writer can only work with Python …

Here’s a simplified visual that shows how pandas performs “segmentation” (grouping and aggregation) based on the column values! Pandas .groupby in action. Let’s do the above presented grouping and aggregation for real, on our zoo dataframe! We have to fit in a groupby keyword between our zoo variable and our .mean() function:

Return subsets of vectors or data frames which meet conditions. It achieves the same purpose as entering boolean conditions in dimensions of a matrix or dataframe, but it's syntax can be simpler or more transparent. Important: 'subset' drops cases that are missing on the index variable, whereas brackets includes these cases as rows of NA's.

The creation of randomized landscape realizations was implemented in ArcGIS v. 9.3 (ESRI 2008) using scripts written in the Python language (van Rossum 2008; Appendix A). I calculated the same set of landscape metrics from the land-cover data found within each randomized landscape (Table 2) using Fragstats v. 3.3 (McGarigal et al 2002).
