Python – Reform K digit elements
When it is required to reform K digit elements, a list comprehension and the ‘append’ method are used.
Example
Below is a demonstration of the same
my_list = [231, 67, 232, 1, 238, 31, 793]
print("The list is :")
print(my_list)
K = 3
print("The value of K is ")
print(K)
temp = ''.join([str(ele) for ele in my_list])
my_result = []
for index in range(0, len(temp), K):
my_result.append(int(temp[index: index + K]))
print("The resultant list is :")
print(my_result)Output
The list is : [231, 67, 232, 1, 238, 31, 793] The value of K is 3 The resultant list is : [231, 672, 321, 238, 317, 93]
Explanation
A list is defined and is displayed on the console.
The value for K is initialized and is displayed on the console.
A list comprehension is used to iterate over the elements in the list and convert it to a string type, and join it by spaces.
This is assigned to a variable.
An empty list is defined.
The value up to K is iterated over and the elements from index 0 to K is appended to the empty list.
This is the output which is displayed on the console.
