Question

Using Python - Pandas and Numpy Data Structures:

*use np.randint create 2 columns of 10 random numbers from dataframe

*Code for creating and printing a 2 by 3 numpy array of random numbers

Answer 1

1)answer)*use np.randint create 2 columns of 10 random numbers from dataframe

import pandas

import numpy

dataframe = pandas.DataFrame(numpy.random.randint(0,1000,size=(5, 2)), columns=['Column1','Column2'])

print(dataframe)

here random number are for 0 to 1000.1000 is excluded.

here Column1 and Column2 are columns of dataframe

size=(5,2) represents 5 rows and 2 columns

2)answer)

*Code for creating and printing a 2 by 3 numpy array of random numbers

import numpy

matrix = numpy.random.random((2,4))

print(matrix)

output:

[[0.59318327 0.9456122 0.7911109 0.21969092]
[0.24625455 0.20927113 0.9708574 0.85175868]]
