Method 1

On a Python version where dicts actually are ordered, you can do

my_dict = {'foo': 'bar', 'spam': 'eggs'}
next(iter(my_dict)) # outputs 'foo'

For dicts to be ordered, you need Python 3.7+, or 3.6+ if you’re okay with relying on the technically-an-implementation-detail ordered nature of dicts on Python 3.6.

For earlier Python versions, there is no “first key”, but this will give you “a key”, especially useful if there is only one.
