The PageView constructor basically takes the default path as 'https://public.wiwdata.com/engineering-challenge/data/' where all the csv files are located. We can change the argument to the constructor to take any location, but it assumes that the files names are alphabet csv files. we also create the name of the output.csv file and merge.csv file when all the a.csv...... to z.csv are merged. And the output file consists of the format in which the code output has to be.
to Execute the code , check out or download the file and run the python script using the command
from the directory in which the file is located and it will create two files, merge.csv which is the big file from concatinating all the csv's. And the Output.csv which is the file output which is desired.
See the sample output to run the script.
