Python syntax error with function

Question

My python code wont work for some reason. It says the error is coming from the syntax of the function but im not sure why its doing that

one=1
two=2
three=3
four=4
five=5
six=6
seven=7
eight=8
nine=9
ten=10
print "test"
def convert()
  number = raw_input('Enter the number you need converted to binary')
enterYourCommand = raw_input("Enter your command")
if enterYourCommand is "convert"
  convert()
elif enterYourCommand is "tonumber"
  tonumber()

you are missing colons `:` after your `def`, `if` and `elif` statements. — Tadhg McDonald-Jensen, Aug 30 '16 at 18:06
Besides the colon issue, you will soon discover the difference between `==` and `is` — Will, Aug 30 '16 at 18:18

You don't have : after function definition and if's:

one=1
two=2
three=3
four=4
five=5
six=6
seven=7
eight=8
nine=9
ten=10
print "test"

def convert():
  number = raw_input('Enter the number you need converted to binary')

enterYourCommand = raw_input("Enter your command")

if enterYourCommand is "convert":
  convert()
elif enterYourCommand is "tonumber":
  tonumber()

You missed the colons after if, elif and def. You have to indent with four spaces. See this link for examples.

one = 1
two = 2
three = 3
four = 4
five = 5
six = 6
seven = 7
eight = 8
nine = 9
ten = 10

enterYourCommand = raw_input("Enter your command")

def convert():
    number = raw_input('Enter the number you need converted to binary')

if enterYourCommand == "convert":
    convert()
elif enterYourCommand == "tonumber":
    tonumber()

Hope it helps.

EDIT

Replace is with ==.

is will return True if two variables point to the same object
== will return True if the objects referred to by the variables are equal.

It doesnt have anymore errors but when i enter convert as raw input its asking me for the if statement doesnt detect it and do the convert function. Any ideas why? – Kody Simpson Aug 30 '16 at 19:11
See the edited answer. It uses `==` instead of `is` to get it work. – JazZ Aug 30 '16 at 20:00

All python functions should have a colon : at the end of their declaration line.

For example:

    def convert():
        number = raw_input('Enter the number you need converted to binary')

Also, the same is with your if and elif declarations:

    if enterYourCommand is "convert":
        convert()
    elif enterYourCommand is "tonumber":
        tonumber()

So, just add : at the end of each declaration and you should be good to go.
