Pandas is a powerful and versatile Python library designed for data manipulation and analysis. It provides two primary data structures: DataFrames and Series, which are used to represent tabular data and one-dimensional arrays, respectively. These structures make it easy to work with large datasets,...
How do I perform a union of two Pandas DataFrames using pd.concat? To perform a union of two Pandas DataFrames usingpd.concat, you can concatenate them along the rows (axis=0). This operation combines the rows of both DataFrames, and the resulting DataFrame will include all unique rows ...
Compared to themerge()andjoin()of DataFrame, theconcat()function is more flexible and efficient. It allows users to join DataFrameseither row-wise (vertically) or column-wise (horizontally). Theconcat()function combines two DataFrames by the indices of both DataFrames' values. Syntax: Syntax...
A cheat sheet for common data journalism stuff. For details on installing these tools, see how I work. Use CMD + F to search the page, or the jump menu below if you know what you're looking for. Jump to: Command line tools grep | head/tail | ffmpeg | pdftk | esridump | wget ...
Added aversioncolumn to both data frames to note the origin of each row when we later combine them. Combined the contents of the two data frames and stored them in another data framefull_set. Removed duplicate rows, i.e. unchanged data, fromfull_setand stored the remaining data inchanges....

(vbCrLf is two characters...CR and LF). These functions also have versions that do not add any extra characters. They are identifiable by the lack of the word Line in them (Read, for example, which will need a length, or size to read.)VB...
We now need to split the data into training and testing samples, which we do with the help of the train_test_split function. We also prepare two separate target arrays. “yC” contains targets for the classification model based on encoded price band and “yR” contains ...
