# Python – Split Numeric String into K digit integers

• Last Updated : 02 Sep, 2020

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.

## Python3

 `# Python3 code to demonstrate working of ``# Split Numeric String into K digit integers``# Using list comprehension + int() + slicing`` ` `# initializing string``test_str ``=` `'457336842'`` ` `# printing original string``print``(``"The original string is : "` `+` `str``(test_str))`` ` `# initializing substring``K ``=` `3`` ` `# one liner to solve problem``res ``=` `[``int``(test_str[idx : idx ``+` `K]) ``for` `idx ``in` `range``(``0``, ``len``(test_str), K)]`` ` `# printing result ``print``(``"Converted number list : "` `+` `str``(res)) `

Output

```The original string is : 457336842
Converted number list : [457, 336, 842]
```
