# #Iterators and Generators Homework 
# 
# ###Problem 1
# 
# 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


# ###Problem 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[6]:


import random

random.randint(1,10)


# In[7]:


def rand_num(low,high,n):
    pass


# In[9]:


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


# ###Problem 3
# 
# Use the iter() function to convert the string below 
# 

# In[1]:


s = 'hello'

#code here


# ###Problem 4
# 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.
# 
# 

# 

# ### Extra Credit!
# 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


# Hint google: generator comprehension is!
# 
# #Great Job!
