You can create any program you can imagine without creating any functions. So why is it useful to create functions?

For each of the following snippets of Python code, give what would be printed to the command line if run. If the snippet will not print anything because of an error, just put error.

1. eggs = 7
   
   if eggs > 0 and eggs < 5:
       print(eggs)
   if eggs < 7:
       print(eggs ** 2)
   else:
       print(eggs // 2)
         

2. def spam(eggs):
       return eggs * eggs
   ham = spam(spam(2))
   print(ham)

3. eggs = 0
   
   def spam(ham):
       eggs = ham
   
   spam(7)
   print(eggs)

4. def spam(eggs, ham):
       eggs = ham
       return ham
   eggs = 2
   ham = eggs + 1
   spam(eggs, ham)
   print(eggs)

5. def spam(eggs, ham):
       bacon = 0
       if (eggs > 0):
           if (ham  < 0):
   	    bacon = eggs + -1 * ham
       else:
           if ham > 0:
   	    bacon = -1 * eggs + ham
       return bacon
   
   print(spam(-1, -1))
   

6. spam = 0
   for i in range(1, 5):
       spam = spam * i
   print(spam)
         

7. def spam(eggs):
       ham = 0
       if eggs % 2 == 0:
           ham = eggs
       return ham
   
   accumulator = 0
   for i in range(10):
       accumulator += spam(i)
         

Write a function called lazy_increase(n), which returns \(2 \times n\) if n is odd and divisible by 3. It should return \(1.5 \times n\) if n is odd and not divisible by 3. It should return \(n\) in all other cases.
