I am in a Fundamentals of Programming class which we are using Python. In the book was a simple code to solve a problem where a cook knows in cups how much he needs but we are converting it to ounces. I was playing around with that and trying to figure out the if-else, elif commands. It is telling me where it says

```
if choice ==1:
```

that there is a syntax error.

Can someone let me know what I am doing wrong?

```
def main():
intro()
c2o = 1
o2c = 2
choice = int(input('Enter 1 if you would like to convert cups to ounces', \
'or enter 2 if you would like to convert ounces to cups.')
if choice == 1:
cups_needed = int(input('Enter the number of cups: '))
cups_to_ounces(cups_needed)
elif choice == 2:
ounces_needed = int(input('Enter the number of ounces: '))
ounces_to_cups(ounces_needed)
print()
def intro():
print('This program converts measurements')
print('in cups to fluid ounces or fluid ounces to cups. For your')
print('reference the formula is:')
print(' 1 cup = 8 fluid ounces or 8 fluid ounces = 1 cup')
print()
def cups_to_ounces(cups):
ounces = cups * 8
print('That converts to', ounces, 'ounces.')
def ounces_to_cups(ounces):
cups = ounces / 8
print('That converts to', cups, ' cups.')
main()
```
