problem with syntax error

[jobemorgan]

I am just practicing with python and I keep getting invalid syntax pop up. I want it to end the script if the user says no. Please help!

print (" Hello, I will be asking you multiple questions to build a profile of who you are.")
answer = input ("Is this ok?")
if answer == ("no") 
import sys
sys.exit()
if awnser == ("yes")             
Name = input(" First of all, what is your name?")
print ("Ahh, hello " + Name )
Age = input ("Now " + Name + " What is your age? Now I must ask you enter this in numbers otherwise I will get confused")
Address = input ("What is your address?"
