Introduction to API
API or Application Programming Interface refers to a number of preset programs. Before utilization, it is required to import API library:
# for myBuddy
from pymycobot.mybuddy import MyBuddy
Notice: Functions with return value are required to use
print()
to print value. For example, if you want to get the speed value, typeprint(get_speed())
, instead ofget_speed()
.
