Don't understand this conversion program's elif syntax error

-6

I'm running this in python 3 and it keeps telling me there's a traceback. elif is a syntax error. I've tried to troubleshoot but I just can't fix it. When helping me could you please fix the code directly since i'm not good with implementing foreign code. It's meant to return back the please select your conversion if the following options are not selected but obviously not working. Thank You!

from turtle import Screen, Turtle



print("Please select your conversion:")



invalid_input = True

def Converter() :

  conversion = input ("metric to metric type mm, metric to imperial type mi, units of water type w, for physics equations type p, for math equations type m and for quick facts type q:")

  print("Please select your conversion:")



  if conversion == "mm":

    #selection = "metric to metric conversions!"



  elif conversion == "mi":

    selection = "metric to imperial conversions!"

    invalid_input = False

  elif conversion == "w":

    selection = "water conversions!"

    invalid_input = False

  elif conversion == "p":

    selection = "physics equations!"

    invalid_input = False

  elif conversion == "m":

    selection = "maths equations!"

    invalid_input = False

  elif conversion == "q":

    selection = "quick facts!"

    invalid_input = False

  else:

    print("n")

    print("Invalid! Please try again.n n n")

while invalid_input : 





print("n")

print("You have selected", selection + "!")



invalid_input = True

def start() :

  decision = input ("Is this correct? If correct type y, if incorrect type n.")

  if decision == "y":

        #stuff

        invalid_input = False

while invalid_input : # this will loop until invalid_input is set to be True

    start()

Can you please add in the stacktrace? Or perhaps even a link to something like a repl or fiddle with your code?

You have commented the only statement selection ... below the if statement - it needs at least pass below it

Once you get the syntax issue figured-out, I suggest you read Asking the user for input until they give a valid response.

Python expects some code (at least one line) inside your conditionals. If you don't have anything to put right now, you can put pass:

if conversion == "mm":

    #selection = "metric to metric conversions!"

    pass

elif conversion == "mi":

    #selection = "metric to imperial conversions!"

    pass

elif conversion == "w":

    #selection = "water conversions!"

    pass

elif conversion == "p":

    #selection = "physics equations!"

    pass

elif conversion == "m":

    #selection = "maths equations!"

    pass

elif conversion == "q":

    #selection = "quick facts!"

    pass
