Question

LEVEL ONE

1. Lists and indexing
   1. Create a list x that spans 1 to 100 using 5 unit increments.

                                Hint: Use the inline for and range().

2. Create a list y containing the elements from x that are divisible by 2.

                                Hint: Explore the for … if … statement.

3. Do b. in another manner. Hint: Use , e.g., array() and where() from numpy.

LEVEL TWO

1. Arrays in numpy
   1. Create an array x that contains a random set of 100 uniform(0,10) variables.

2.                                 Hint: Explore numpy.random.rand().

3. 2. Find the values in x greater than 5.
   3. Find the maximum and minimum values without sorting. Hint: Explore numpy.min() and numpy.max().
4. 4. Find the indices associated with the min/max in c.   Hint: Explore numpy.argmin() and numpy.argmax().

NB: THIS IS A PYTHON ASSIGNMENT   

Answer 1

Level One

x = [ele for ele in range(1,100,5)] # list x from 1 to 100 with interval of 5
print(x) #print list x

y = [num for num in x if num % 2 == 0] # list y which has elements from x divisble by 2
print(y) #print list y

Using Numpy

import numpy as np #import numpy package
x = np.arange(1,100,5) # array x from 1 to 100 with interval of 5
print(x) #print array x

y = x[np.where(x%2==0)] # array y which has elements from x divisble by 2
print(y) #print array y

Level Two

x = np.random.uniform(0,10,100) # array of 100 elements in uniform distribution with low = 0 and high = 10

print(x[x>5]) # values from x which are greater than 5
print("*"*100)
print(min(x), max(x)) #minimum and maximum value of array x
print("*"*100)
print(np.argmin(x), np.argmax(x)) # index of minimum and maximum value of x
