As we know Pandas is all-time great tools for data analysis. One of the most important data type is dataframe. It is a 2-dimensional labeled data structure with columns of potentially different types. It is generally the most commonly used pandas object.
Pandas DataFrame can be created in multiple ways. Let’s discuss how to create Pandas dataframe using dictionary of ndarray (or lists).
Let’s try to understand it better with few examples.

Note: To create DataFrame from dict of narray/list, all the narray must be of same length. If index is passed then the length index should be equal to the length of arrays. If no index is passed, then by default, index will be range(n) where n is the array length.
