Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.

print('Start time:', t1.time())

t2 = datetime.strptime(end_time, "%H:%M:%S.%f")
print('End time:', t2.time())
