Python – Extract Rear K digits from Numbers
When it is required to extract rear K digits from numbers, a simple list comprehension, the modulo operator and the ‘**’ operator are used.
Below is a demonstration of the same −
Example
my_list = [51645, 24567, 36743, 89452, 2122]
print("The list is :")
print(my_list)
K = 3
print("The value of K is ")
print(K)
my_result = [element % (10 ** K) for element in my_list]
print("The result is :")
print(my_result)Output
The list is : [51645, 24567, 36743, 89452, 2122] The value of K is 3 The result is : [645, 567, 743, 452, 122]
Explanation
A list is defined and displayed on the console.
The value for K is defined and is displayed on the console.
A list comprehension is used to iterate over the list, and integer 10 is raised to power of K.
Every element is divided by the above operation’s result, and remained is stored in a list.
This result is assigned to a variable.
This is the output that is displayed on the console.
