Iterators and Generators Homework

Create a generator that generates the squares of numbers up to some number N.



In [10]:

    
def gensquares(N):
    pass



In [11]:

    
for x in gensquares(10):
    print x

Create a generator that yields "n" random numbers between a low and high number (that are inputs). Note: Use the random library. For example:



In [6]:

    
import random

random.randint(1,10)









    Out[6]:





6



In [7]:

    
def rand_num(low,high,n):
    pass



In [9]:

    
for num in rand_num(1,10,12):
    print num

Use the iter() function to convert the string below



In [1]:

    
s = 'hello'

#code here

Explain a use case for a generator using a yield statement where you would not want to use a normal function with a return statement.

Can you explain what gencomp is in the code below? (Note: We never covered this in lecture! You will have to do some googling/Stack Overflowing!)



In [18]:

    
my_list = [1,2,3,4,5]

gencomp = (item for item in my_list if item > 3)

for item in gencomp:
    print item

4
5

Hint google: generator comprehension is!

Great Job!
