@sayzlimAug 12.2022 — #We're talking about Python variables here. The "df" is usually a named variable that we refers to Pandas DataFrame. You can also call it something else.
We often use df['x'] to refer the header name of your tabular data. For example, if you have a DataFrame with the following headers:
Title, Description, Price
You can refer to your DataFrame's "Title" with df["Title"]
