# Printing Subscript and Superscript in Python

Subscript and superscript are important when you are dealing with different types of formulas. They are useful in math, chemistry, etc.

In Python, there is a method called maketrans. It creates a one-to-one mapping table with characters and their replacements.

This method will replace 1 to A, 2 to B, and 3 to C. Let’s take a look.

In this case, numbers 1 and 2 are going to be replaced, but 4 doesn’t have a replacement, so it will stay 4.

`Question A, point B and 4`

## Printing subscript

Similarly, you can convert numbers to subscripts. Let’s use this formula for ethanol:

This code will replace all numbers with subscripts, as it should be in the chemical formula.

`C₂H₅OH`

## Printing superscript

You can also convert a number to superscript. In this case, we are going to use a formula to calculate the area of a circle.

`πr²`

In our example, the formula is written this way:

`PIr2`

We are going to convert 2 to superscript, and PI to π. We can’t convert PI with maketrans because the first two maketrans arguments should be the same length. In this case, let’s use the replace function.

The result is:

`πr²`

## Unicode subscripts and superscripts

Another way to achieve the same result is to use Unicode subscripts and superscripts.

### For subscripts

`U+207x`

The letter “x” represents a subscript number.

### For superscripts

`U+208x`

The letter “x” represents a superscript number.

This is the full table of Unicode characters:

Let’s implement it into Python.

The result is the same as before:

`C₂H₅OH`

Now, let’s create the second formula:

U+03C0 is a Unicode character for the greek letter PI and U+00B2 for the square root. As you can see from the table, the power of 2 and 3 have different notation than numbers from 4 to 9.

The result:

`πr²`
