#1. Import the NUMPY package under the name np.

import numpy as np


#2. Print the NUMPY version and the configuration.


print(np.__version__)
print(np.__config__)

#3. Generate a 2x3x5 3-dimensional array with random values. Assign the array to variable "a"
# Challenge: there are at least three easy ways that use numpy to generate random arrays. How many ways can you find?


import random as rd
a = np.random.random((2,3,5))

#4. Print a.

print(a)


#5. Create a 5x2x3 3-dimensional array with all values equaling 1.
#Assign the array to variable "b"

b = np.ones((5,2,3))


#6. Print b.

print(b)


#7. Do a and b have the same size? How do you prove that in Python code?


a.size == b.size
# Yes


#8. Are you able to add a and b? Why or why not?


try:
a + b
except:
print("Error")
# Can't add a and b while they have different shapes

#9. Transpose b so that it has the same structure of a (i.e. become a 2x3x5 array). Assign the transposed array to varialbe "c".

c = np.transpose(b, (1,2,0))
c.shape


#10. Try to add a and c. Now it should work. Assign the sum to varialbe "d". But why does it work now?

d = a + c
# Works now because a and c has equal shape


#11. Print a and d. Notice the difference and relation of the two array in terms of the values? Explain.
print(a)
print("\n")
print(d)



# The difference for each position between both arrays is 1

#12. Multiply a and c. Assign the result to e.

e = a * c


#13. Does e equal to a? Why or why not?

# Yes, because each element of a is multiplied by 1, so the result is the same



#14. Identify the max, min, and mean values in d. Assign those values to variables "d_max", "d_min", and "d_mean"

d_max = d.max()
d_min = d.min()
d_mean = d.mean()



#15. Now we want to label the values in d. First create an empty array "f" with the same shape (i.e. 2x3x5) as d using `np.empty`.

f = np.empty((d.shape), dtype="int")
