Python From Zero 07 — CSV Files
Python From Zero 07 — CSV Files
In this video we do a first introduction to working with CSV data in Python.
We briefly cover:
what CSV files actually are
opening files normally in Python
read mode
CSV is still just text underneath
Python’s csv module
csv.reader
csv.DictReader
rows and columns
simple data processing
exporting CSV files
We begin with one CSV file.
Then step by step we:
import it into Google Colab
open it as a normal file
parse the CSV data
load rows into dictionaries
add new rows
add a new column
modify the dataset
and finally export everything into a brand new CSV file
So by the end:
we start with one CSV...
and Python generates another one.
Everything is written and executed live using Python in Google Colab.
This series starts from absolute zero and builds step by step toward real programming concepts and projects.
