Pandas DataFrame.ndim property returns the number of dimensions of the DataFrame, which is always 2.

WARNING

This property has nothing to do with the number of rows and columns of the DataFrame. If you're after the number of rows and columns, then use the DataFrame's shape property instead.

Examples

Consider the following DataFrame:

df = pd.DataFrame({"A":[4,5],"B":[6,7],"C":[8,9]}, index=["a","b"])
df
   A  B  C
a  4  6  8
b  5  7  9

Here's its ndim property:

df.ndim
2

Note that for DataFrames, the return value is always 2, regardless of the number of rows and columns.
