[Python-ideas] datetime.timedelta literals

[Robert Vanden Eynde]

second, minute, hour (singular) timedelta objects in the module are a good
idea, one could do 5 * minute to get a timedelta or one could do value /
minute to get a float.

a = datetime.now()
b = datetime(2018, 2, 3) + 5 * minute
print((a - b).total_seconds())
print((a - b) / minute)
