I just love generators in Python.
One of the cool things I found out from this site was that one could send in a value when calling on an active generator.
To do so one uses the send() method and a yield like so: "x = yield".
The send with a value will assign the sent value to the variable associated with the yield.
I used this once to iterate through my generator once with one set of values, and then later with a different set.
Cool stuff.
# Main #
def main():
# Main Code
go_Test = g_Test() ## Create gen. obj. instance
go_Test.send(None) ## Inits gen. and also sends a "None" value
go_Test.send(4) ## Sends a 4 to the gen. to start it again, but this 4 is lost, as there is no assign on the "yield"
go_Test.send(7) ## Sends a 7 to the gen. to run it again.
#-----------Basement------------
def g_Test():
x = 1
yield ## First send returns here, but there is no assign so "x" stays "1" and sent "4" is ignored/lost
while True:
print("x is: %s") %(x) ## Will print "1", as "4" has been lost.
x = yield ## Mid-stream yield that will assign to "x" when sent into gen. again.
print("x is: %s") %(x) ## 7
yield
