Is there a difference between using a dict literal and a dict constructor?

Question

Using PyCharm, I noticed it offers to convert a dict literal:

d = {
    \'one\': \'1\',
    \'two\': \'2\',
}

Answer 1

Also consider the fact that tokens that match for operators can't be used in the constructor syntax, i.e. dasherized keys.

>>> dict(foo-bar=1)
File "", line 1
SyntaxError: keyword can't be an expression

>>> {'foo-bar': 1}
{'foo-bar': 1}
