Python: Configure the rounding to round to the floor, ceiling
Python module: Exercise-4 with Solution
Write a Python program to configure the rounding to round to the floor, ceiling. Use decimal.ROUND_FLOOR, decimal.ROUND_CEILING
Sample Solution:
Python Code:
import decimal
print("Configure the rounding to round to the floor:")
decimal.getcontext().prec = 4
decimal.getcontext().rounding = decimal.ROUND_FLOOR
print(decimal.Decimal(20) / decimal.Decimal(6))
print("\nConfigure the rounding to round to the ceiling:")
decimal.getcontext().prec = 4
decimal.getcontext().rounding = decimal.ROUND_CEILING
print(decimal.Decimal(20) / decimal.Decimal(6))
Sample Output:
Configure the rounding to round to the floor: 3.333 Configure the rounding to round to the ceiling: 3.334

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']}
