<｜begin▁of▁sentence｜>### Instruction:
Given a weighted graph that you can read from a file (e.g., 'graph_weighted.gml'), and provided two groups of vertices represented as lists (e.g., `group1=[0, 1, 2]` and `group2=[3, 4, 5]`), how do you calculate and print the minimum edge cut between these two vertex groups?
### Response:
import igraph as ig

# Assuming you have a weighted graph `g` with an edge cut
# Calculate the edge cut between two groups of vertices:
group1 = [0, 1, 2]
group2 = [3, 4, 5]
mincut = g.mincut(group1, group2)

# Print a human-readable string of the cut
print(str(mincut.cut))
