1. Code is already written please show all outputs and comment on function of code.

2. These are Python 3 programs. Please show outpouts and comment on fuctions.

Note: this is a bit of a “backwards” exercise – we show you code, you figure out what it does.

As a result, not much to submit – don’t worry about it – you’ll have a chance to use these in other exercises.

What is the output of:

(figure it out before you try it)

Filtering lists with list comprehensions

What is the output of:

(figure it out first!)

Unpacking tuples in list comprehensions

What is the output of:

Double list comprehensions

What is the output of:

What is the output of:

Solution

Code:

import os
import sys

feast = [\'lambs\', \'sloths\', \'orangutans\',\'breakfast cereals\', \'fruit bats\']
comprehension = [delicacy.capitalize() for delicacy in feast]
print comprehension[0]
print comprehension[2]

feast = [\'spam\', \'sloths\', \'orangutans\', \'breakfast cereals\',\'fruit bats\']
comp = [delicacy for delicacy in feast if len(delicacy) > 6]
print len(feast)
print len(comp)
list_of_tuples = [(1, \'lumberjack\'), (2, \'inquisition\'), (4, \'spam\')]
comprehension = [ skit * number for number, skit in list_of_tuples ]
print comprehension[0]
print len(comprehension[2])
eggs = [\'poached egg\', \'fried egg\']
meats = [\'lite spam\', \'ham spam\', \'fried spam\']
comprehension = [ \'{0} and {1}\'.format(egg, meat) for egg in eggs for meat in meats]
print len(comprehension)
print comprehension[0]
comprehension = { x for x in \'aabbbcccc\'}
print comprehension

output:

Lambs
Orangutans
5
3
lumberjack
16

poached egg and lite spam
set([\'a\', \'c\', \'b\'])
