A data frame is a structured representation of data.
A data frame is a two-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or a SQL table. A data frame is a two-dimensional, resizable, and potentially heterogeneous tabular data structure with labeled axes (rows and columns). A data frame is a two-dimensional data structure. Rows and columns aggregate H. Data.
Let's define a data frame with 3 columns and 5 rows containing fictitious numbers.
You can see that 'col1', 'col2', and 'col3' are the names of the columns.
Don't be fooled by the vertical numbers from 0 to 4. They provide information about the line's position. In Python, line numbers start at 0.
Now you can count columns and rows using Python.
