Comprehensions

# Create a list 
list1 = ['a', 'b', 'c']

# Create a comprehension 
list2 = [x for x in list1]

list3 = [x for x in list1 if x == 'a']

list4 = [x for x in range(5)]

# Generate values in hex
list5 = [hex(x) for x in range(5)]

list6 = [hex(x) if x > 0 else "X" for x in range(5)]

list7 = [x * x for x in range(5)]

list8 = [x for x in range(5) if x == 0 or x == 1]

list9 = [[1,2,3],[4,5,6],[7,8,9]]

list10 = [y for x in list9 for y in x]

list11 = [c for c in "string"]

# Use join 
print("".join(list11))
