## Finding Ones, Tens, Hundreds, and Thousands Digits

As we use math in our day-to-day life, the need to break down numbers to obtain their digits arises quite frequently. For instance, on your paycheque, you would want to know how much you have earned, be it in the hundreds or thousands.

Here, we will discuss different methods to identify ones, tens, hundreds, and thousands digits of a number using Python.

## Using Math to Find Digits

To begin with, let’s identify the digits of a number using mathematical operators. In Python, the modulo operator (%) returns the remainder of a division.

### Finding the Ones Digit

To find the ones digit, we can use the modulo operator. Here’s how:

```
num = 123
ones = num % 10
print("Ones digit: ", ones)
```

### Output:

```
Ones digit: 3
```

### Finding the Tens Digit

The floor division (//) operator returns the largest integer that is smaller than or equal to the result of division.

To get the tens digit, divide the number by 10, and then do floor division by 10. Here’s an example:

```
num = 123
tens = (num // 10) % 10
print("Tens digit: ", tens)
```

### Output:

```
Tens digit: 2
```

### Finding the Hundreds and Thousands Digits

To obtain the hundreds and thousands digits, we use the same approach.

Divide the number by 100 for the hundreds digits and by 1000 for the thousands digits. Here’s the code:

```
num = 1234
hundreds = (num // 100) % 10
thousands = (num // 1000) % 10
print("Hundreds digit: ", hundreds)
print("Thousands digit: ", thousands)
```

### Output:

```
Hundreds digit: 2
Thousands digit: 1
```

## Using List Comprehension to Find Digits

Another way to obtain digits is by using list comprehension. We can convert the number into a string and then apply slicing.

Here’s how:

```
num = 1234
digits = [int(d) for d in str(num)]
ones, tens, hundreds, thousands = digits[-1], digits[-2], digits[-3], digits[-4]
print("Ones digit: ", ones)
print("Tens digit: ", tens)
print("Hundreds digit: ", hundreds)
print("Thousands digit: ", thousands)
```

### Output:

```
Ones digit: 4
Tens digit: 3
Hundreds digit: 2
Thousands digit: 1
```

## Using a While Loop to Find Digits

The final approach we will discuss uses a while loop. This method is more complex than the previous ones but is useful when we want to obtain all digits of a large number.

Let’s see an example:

```
num = 246357
digits = []
while num>0:
digits.insert(0,num%10)
num //= 10
ones, tens, hundreds, thousands, ten_thousands, hundred_thousands = digits[-1], digits[-2], digits[-3], digits[-4], digits[-5], digits[-6]
print("Ones digit: ", ones)
print("Tens digit: ", tens)
print("Hundreds digit: ", hundreds)
print("Thousands digit: ", thousands)
print("Ten thousands digit: ", ten_thousands)
print("Hundred thousands digit: ", hundred_thousands)
```

### Output:

```
Ones digit: 7
Tens digit: 5
Hundreds digit: 3
Thousands digit: 6
Ten thousands digit: 4
Hundred thousands digit: 2
```
