Python: Make an iterator that returns evenly spaced values starting with a specified number and step
Python Itertools: Exercise-4 with Solution
Write a Python program to construct an infinite iterator that returns evenly spaced values starting with a specified number and step.
Sample Solution:
Python Code:
import itertools as it
start = 10
step = 1
print("The starting number is ", start, "and step is ",step)
my_counter = it.count(start, step)
# Following loop will run for ever
print("The said function print never-ending items:")
for i in my_counter:
print(i)
Sample Output:
The starting number is 10 and step is 1 The said function print never-ending items: 10 11 12 13 14 15 16 17 18 19 20 .... 25869 .... 1

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']}
