Solution Review: Coroutine to Compute Running Maximum

import math
def maximum():
  result = - math.inf
  while True:
    value = yield result  # Recieving values
    if value > result:    # Deciding on maximum
      result = value  
coroutine = maximum()
next(coroutine)
# Sending values 
print(coroutine.send(1))
print(coroutine.send(7))
print(coroutine.send(3))
print(coroutine.send(10))
print(coroutine.send(5))
print(coroutine.send(8))
print(coroutine.send(12))
coroutine.close() # Closing coroutine
