DataFrame constructor accepts a data object that can be ndarray, dictionary etc. i.e. pandas.DataFrame(data=None, index=None, columns=None, dtype=None, copy=False) But if we are passing a dictionary in data, then it should contain a list like objects in value field like Series, arrays or lists etc i.e. # Dictionary with list object in values

brightness_4. import pandas as pd. data = … The DataFrame.head () function in Pandas, by default, shows you the top 5 rows of data in the DataFrame.

Pandas DataFrame is the Data Structure, which is a 2 dimensional Array. One can say that multiple Pandas Series make a Pandas DataFrame. DataFrames are visually represented in the form of a table. DataFrames are one of the most integral data structure and one can’t simply proceed to learn Pandas without learning DataFrames first.
