# [Python] How to get function signature
#
import inspect
def myfunc(a, b, multiplier=1.0):
return multiplier*(a + b)
print("myfunc(1,2) is:", myfunc(1,2))
sig = inspect.signature(myfunc)
msg = "function signature is: " + str(sig)
print(msg)
Note that the signature sig above is not a string (a Python str object). Must be cast to a Python str to concatenate with a string as shown in computing msg.
