# Advanced Python Objects Test

# Advanced Numbers
# Problem 1: Convert 1024 to binary and hexadecimal representation:
print hex(1024)
print bin(1024)

# Problem 2: Round 5.23222 to two decimal places
print round(5.23222, 2)


# Advanced Strings
# Problem 3: Check if every letter in the string s is lower case
s = 'hello how are you Mary, are you feeling okay?'
print s.islower()

# Problem 4: How many times does the letter 'w' show up in the string
# below?
s = 'twywywtwywbwhsjhwuwshshwuwwwjdjdid'
print s.count('w')


# Advanced Sets
# Problem 5: Find the elements in set1 that are not in set2:
set1 = {2, 3, 1, 5, 6, 8}
set2 = {3, 1, 7, 5, 6, 8}
print set1.difference(set2)

# Problem 6: Find all elements that are in either set:
# print set1.intersection(set2)
print set1.union(set2)

# Advanced Dictionaries
# Problem 7: Create this dictionary:
# {0: 0, 1: 1, 2: 8, 3: 27, 4: 64} using dictionary comprehension.
print {x: x**3 for x in range(5)}


# Advanced Lists
# Problem 8: Reverse the list below:
l = [1, 2, 3, 4]
l.reverse()
print l

# Problem 9: Sort the list below
l = [3, 4, 2, 5, 1]
l.sort()
print l
# Great Job!
