2,157 PointsHow to import a package to a class in python
I want to import a package named tsp to my class named 'Tour'. When I run the file without a class and a method, it works well. Tsp is an algorithm for finding the fastest route through a given list of cities and the distances between them. But I want to implement this using Object oriented programming. When I try to run the code I get the following message: "AttributeError: module 'tsp' has no attribute 'tsp':" So my question is, how can I import 'tsp' to my class 'Tour'?
import tsp
class Tour:
def fastestWay(self):
A = []
B=[ 0,6.47, 7.10, 6.10,3.65 ] # Oslo
C=[7.14, 0, 4.42, 9.30,7.39 ] # Bergen
D=[ 7,4.48, 0,13.37,3.14 ] # Stavanger
E=[6.24,9.34,13.36, 0,10.12] # Trondheim
F=[ 4.3,7.45, 3.33,10.17, 0 ] # Kristiansand
r = range(len(A))
# Dictionary of distance
dist = {(i, j): A[i][j] for i in r for j in r}
#print(tsp.tsp(r, dist))
print(tsp.tsp(r,dist))
i=Tour()
i.fastestWay()

2,157 PointsThe problem was that I had a file called 'tsp.py' in my directory. Therefore it imported the file instead of the package. All I had to do was to rename the tsp.py. Then it worked well.
