Question

Given the following coordinates: (f, 9), (z, 2), (t, 4), (x, 8), (b, 1), (m, 7).

Sort the coordinates in Python (in ascending order) by comparing the second part of the coordinates. You may use the sort() function in Python.

Answer 1

Python code:

# Sort the coordinates in Python (in ascending order) by comparing the second part of the coordinates.
# Using the sort() function in Python.

def last(n):
   return n[m]

# function to sort
def sort(tuples):
   return sorted(tuples, key = last)

# driver code
coordinates = [('z', 9), ('z', 2), ('t', 4), ('x', 8), ('b', 1), ('m', 7)]
m = 1 #key position
print("Sorted:"),
print(sort(coordinates))

Output:
