Hello,Guys!,I met a very strange bug

[homepoeple]

#I am learning Python now ,I have some experience about C#,VB,C.
#The scripture is very easy but I just dont know what's wrong

def eval_loop():
     while True:
        x = input('> ')
        if x== 'done':
            break
        result = eval(x)
        print (result)
eval_loop

#OK that's all code,the problem is it doesnt work, but when I delete def eval_loop(): and eval_loop then it can work.when I use debuging what ever i press F5,F6,F7(IDE Eclipse Version: Oxygen.2 Release (4.7.2)）,the weird thing happen,I set break point on the line of def eval_loop():and while True: but the debuging just stop at def line dont stop at after lines until eval_loop.
#So What should I do?Please tell thanks.

Please post your code in Python code tags. You can find help here.

you need line8 to be

eval_loop()

i.e. you miss parenthesis to actually execute the eval_loop function

What happens when you run the script in the terminal?

I somehow missed that.

Where so many people learn to use eval with input?!
