Comma separated catalogue – Andre + Michael

Screen Shot 2018-04-23 at 15.41.33.png

Pad of the lesson: CSV-libgen

CSV:

  • comma-separated values
  • plain-text file
  • commas are used as field seperators
  • A record ends at a line terminator (such as new line \n)
  • All records have to have the same number of fields

How to handle it? Tools for handling CSV

  • head - output the first part of files
  • tail - output the last part of files
  • CSVKit - "swiss army knife" of CSV files. Install: sudo pip3 install csvkit
Documentation: https://csvkit.readthedocs.io/en/1.0.1/#

What is it? How is it structure? What data does it contain? Is it incomplete or messy?

  • Headers are in seperate file libgen_columns.txt, we might need to integrate it into content.csv, as python CSV library takes the first row of a CSV file as the headers row
  • convert libgen_columns.txt to CSV:

A alternative: cat libgen_columns.txt | sed "s/\ \ \`/\"/g" | sed "s/\`.*/\",/g"| tr --delete '\n'

MAC: cat libgen_columns.txt | sed "s/\ \ \`/\"/g" | sed "s/\`.*/\",/g" | tr -d '\n'

converting txt to csv (MAC): libgen_columns.txt | sed "s/\ \ \`/\"/g" | sed "s/\`.*/\",/g" | tr -d '\n' > headers.csv
