[Python] pySerial wait for "#" character to print output from USB serial device

I'm writing a python script that connects to a USB serial device. Whenever a command is sent and executed, the PIC returns with a hashtag. Ie. "Command executed successfully. \n# "

I'd like my python script to wait for the hashtag before outputting the data. How can I do this? Here's what I have. It doesn't seem to actually print the text received from the PIC. Any help is appreciated

if port.isOpen():
try:
for x in range(0,100):
time.sleep(0.05)
port.write("command 1" + "\r\n")
numLines = 0
// wait for "#" to print output
while True:
response = port.readline()
if "#" in response:
print(response)
numLines = numLines + 1
if(numLines >= 1):
break

time.sleep(0.05)
port.write("command 2" + "\r\n")
numLines = 0
// wait for "#" to print output
while True:
response = port.readline()
if "#" in response:
print(response)
numLines = numLines + 1
if(numLines >= 1):
break

time.sleep(0.05)
port.write("command 3" + "\r\n")
numLines = 0
// wait for "#" to print output
while True:
response = port.readline()
if "#" in response:
print(response)
numLines = numLines + 1
if(numLines >= 1):
break

except Exception, e1:
print("An error occured: " + str(e1))
port.close()
