Python – Split Numeric String into K digit integers
Given a String, convert it to K digit integers
Input : test_str = ‘457336’, K = 2
Output : [45, 73, 36]
Explanation : Divided in 2 digit integers.Input : test_str = ‘457336’, K = 3
Output : [457, 336]
Explanation : Divided in 3 digit integers.
Method #1 : Using int() + slice + loop
In this, we iterate for string and perform slicing till K digits and then perform task of conversion to integer using int().
Python3
# Python3 code to demonstrate working of # Split Numeric String into K digit integers # Using int() + slice + loop # initializing string test_str = '457336842' # printing original string print("The original string is : " + str(test_str)) # initializing substring K = 3 res = [] for idx in range(0, len(test_str), K): # converting to int, after slicing res.append(int(test_str[idx : idx + K])) # printing result print("Converted number list : " + str(res)) |

Output
The original string is : 457336842 Converted number list : [457, 336, 842]
Method #2 : Using list comprehension + int() + slicing
Similar method to above, just a shorthand to solve this problem.
