Iterators and Generators Homework

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

In [1]:

def gensquares(N):

    pass

In [2]:

for x in gensquares(10):
    print(x)

Out[2]:

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 [3]:

import random

random.randint(1,10)

Out[3]:

9

In [4]:

def rand_num(low,high,n):

    pass

In [5]:

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

Out[5]:

Use the iter() function to convert the string below into an iterator:

In [ ]:

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 [6]:

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

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

for item in gencomp:
    print(item)

Out[6]:

4
5

Hint: Google generator comprehension!

Great Job!
