List Comprehension with Dictionaries

Question

Is it possible to use list comprehension with dictionaries? (I'm assuming it's not possible with tuples)

Answer 1

# There are a lot of options for construction
# via dictionary comprehensions
# here's a simple example. Note the {} syntax and
# the : for specifying the key: value pair

my_d = {x:y for x,y in [('a',1),('b',2)]}
print(type(my_d))
print(my_d)

# comprehensions are not always necessary for simple cases
print(dict([('a',1),('b',2)]))
