pandas.Series() function is used to convert the NumPy array to Pandas Series. Pandas Series and NumPy array have a similar feature in structure so,

Finally, you are printing arr_2, and you see for arr_2 as well, the bottom right value has changed from 9 to 42. If you want to generate a copy of an array, you can use np.copy(). Copying an array creates a new place in memory for the copy to be stored, so changes to the...

We will demonstrate methods to convert a float to an integer in a PandasDataFrame-astype(int)andto_numeric()methods. ADVERTISEMENT First, we create a random array using theNumPylibrary and then convert it intoDataFrame. importpandasaspdimportnumpyasnp df=pd.DataFrame(np.random.rand(5,5)*5)pri...
Now, we sort the vector y to ensure that we “stack” x_0 and x_1 corresponding to y=0 and y=1, respectively. Finally, we convert the np arrays into a data frame. y = np.sort(y) print(y) x = np.concatenate((x_0, x_1), axis=None) df = pd.DataFrame({'y':y, 'x':...
