SyntaxError: unexpected EOF while parsing

Question

I have no idea why this does not work please help

import random x = 0 z = input('?') int(z)  def main():     while x < z:         n1 = random.randrange(1,3)         n2 = random.randrange(1,3)         t1 = n1+n2         print('{0}+{1}={2}'.format(n1,n2,t1) 

When i run this it outputs this error

File "/Users/macbook/Documents/workspace/gamlir_filar/samlagning.py", line 12                                                  ^ SyntaxError: unexpected EOF while parsing 

I am using eclipse and python 3.3 and i have no idea why this happens. It sometimes outputs errors like this.

Answer 1

You're missing a closing parenthesis ) in print():

print('{0}+{1}={2}'.format(n1,n2,t1)) 

and you're also not storing the returned value from int(), so z is still a string.

z = input('?') z = int(z) 

or simply:

z = int(input('?')) 

Answer 2

Maybe this is what you mean to do:

import random  x = 0 z = input('Please Enter an integer: ') z = int(z) # you need to capture the result of the expressioin: int(z) and assign it backk to z  def main():     for i in range(x,z):         n1 = random.randrange(1,3)         n2 = random.randrange(1,3)         t1 = n1+n2         print('{0}+{1}={2}'.format(n1,n2,t1))  main() 

1. do z = int(z)
2. Add the missing closing parenthesis on the last line of code in your listing.
3. And have a for-loop that will iterate from x to z-1
