division error - mcgrim - May-06-2019
The following code
class interval:
def __init__(self,left,right):
self.right=right
self.left=left
def __add__(self,other):
a,b,c,d = self.left, self.right, other.left, other.right
return interval(a+c,b+d)
def __sub__(self,other):
a,b,c,d=self.left,self.right,other.left,other.right
return interval(min(a,b)-max(c,d),max(a,b)-min(c,d))
def __mul__(self,other):
a,b,c,d=self.left,self.right,other.left,other.right
return interval(min(a*c, a*d, b*c, b*d),
max(a*c, a*d, b*c, b*d))
def __div__(self, other):
a, b, c, d = self.lo, self.up, other.lo, other.up
# [c,d] cannot contain zero:
print(min(a/c, a/d, b/c, b/d))
if c*d <= 0:
raise ValueError ('Interval %s cannot be denominator because it contains zero' % other)
return interval(min(a/c, a/d, b/c, b/d), max(a/c, a/d, b/c, b/d))
def __repr__(self):
return '[{},{}]'.format(self.left,self.right)
I1 = Interval(1, 4)
I2 = Interval(-2, -1)
print(I1 + I2)
print(I1-I2)
print(I1*I2)
print(I1/I2)gives me the following error:Error:File "C:/Users/Desktop/python ode/homework2.py", line 52, in __truediv__
raise ValueError('Please make sure values is of sort int and x !=0')
ValueError: Please make sure values is of sort int and x !=0RE: division error - Gribouillis - May-06-2019
There are less than 52 lines, how could there be an error on line 52?
RE: division error - mcgrim - May-06-2019
it looks like that the error is contained within the command __truediv__,
therefore might not have anything to do directly with the code I wrote.
RE: division error - Gribouillis - May-06-2019
We need the full error message and we need the file name of the above code in order to see where it fails.
RE: division error - mcgrim - May-07-2019
this is everything that is printed out after I run it.

This code cannot possible run, because you class definition is with small i -
class interval and you instantiate Intervalalso what is homework2.py?
RE: division error - mcgrim - May-07-2019
solved, the problem was the capitalization.
Thanks a lot.
That is the name of the file.

RE: division error - mcgrim - May-07-2019
sorry, I involuntarily created some confusion.
I have two different files next to each other, and I must have copy/pasted
from the other one.
