Python: Rounding to round to the nearest, with ties going to the nearest even integer

Python module: Exercise-6 with Solution

Write a Python program to configure rounding to round to the nearest integer, with ties going to the nearest even integer. Use decimal.ROUND_HALF_EVEN

Sample Solution:

Python Code:

import decimal
print("Configure the rounding to round to the nearest, with ties going to the nearest even integer:")
decimal.getcontext().prec = 1
decimal.getcontext().rounding = decimal.ROUND_HALF_EVEN
print(decimal.Decimal(10) / decimal.Decimal(4))

Sample Output: 

Configure the rounding to round to the nearest, with ties going to the nearest even integer:
2

Python: Tips of the Day

Inverts a dictionary with non-unique hashable values:

Example:

def tips_collect_dictionary(obj):
  inv_obj = {}
  for key, value in obj.items():
    inv_obj.setdefault(value, list()).append(key)
  return inv_obj
ages = {
  "Owen": 25,
  "Jhon": 25,
  "Pepe": 15,
}
print(tips_collect_dictionary(ages))

Output:

{25: ['Owen', 'Jhon'], 15: ['Pepe']}
