<DataFrameObject>. <empty> We have another attribute that can check the presence of NANs (Not a Number). SYNTAX <DataFrameObject>. <isna()> import pandas as pd import numpy as np dict= {'2018':[85,73,80,64], '
In this lesson, let us see such attributes and methods in Python Pandas for DataFrame:dtypes: Return the dtypes in the DataFrame ndim: Return the number of dimensions of the DataFrame size: Return the number of elements in the DataFrame. shape: Return the dimensionality of the DataFrame in ...
shape: gives the axis dimensions of the object, consistent with ndarray Axis labels Series: index (only axis) DataFrame: index (rows) and columns Note, these attributes can be safely assigned to!
