In this example we will pass the numpy array as the input argument to the DataFrame function along with the column names then the array will be converted into Dataframe. Open Compiler importpandasaspdimportnumpy
NumPy arrayis a data structure (usually numbers) that contains values of the same type, similar to a list. But arrays are more efficient than Python lists and also much more compact. Sometimes you would be required to create pandas Series from the NumPy array. Let’screate Numpy arrayusing ...
