I wrote the following code and got the output:
a 13 0
None
b 81 3
None
c 8 2
None
d 9 2
None
e 1 1
None
where are those 'none' from? and how can I remove them?
class Point:
def __init__(self,x,y,name):
self.x = x
self.y = y
self.name = name
def summary(self):
print
self.name,self.x,self.y
if __name__ == '__main__':
from string import letters
m = 13,81,8,9,1
n = 0,3,2,2,1
q=len(x)
points = [ Point(m[i],n[i],letters[i]) for i in range(q) ]
i=0
while i<q:
print points[i].summary()
i=i+1
