Whenever we are working with formulas there may be a need of writing the given formula in a given format which may require subscripts or superscripts. There are several methods available to print subscripts and superscripts in Python. We will be discussing two of them below –

Using maketrans[] and translate[] :

We can make two strings one for the normal characters and the other for the subscript/superscript characters. After this, we can use the maketrans[] method which returns a mapping that can be used with the translate[] method to replace the specified characters. It can be implemented for superscripts as 

Python3

# function to convert to superscript

def get_super[x]:

    normal= "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+-=[]"

H₂SO₄

H₂SO₄
x² + y² = 2

H₂SO₄
x² + y² = 2

H₂SO₄
x² + y² = 2

H₂SO₄
x² + y² = 2

H₂SO₄
x² + y² = 2

H₂SO₄
x² + y² = 2

H₂SO₄
x² + y² = 2

Output:

ᴳᵉᵉᵏˢᶠᵒʳᴳᵉᵉᵏˢ

And for subscripts, we can implement it as

Python3

# function to convert to superscript0

def # function to convert to superscript2

    normal= "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+-=[]"

    # function to convert to superscript8= def0

x² + y² = 2

get_super[x]:1

H₂SO₄
x² + y² = 2

In Windows, Alt key combined with numeric codes can access characters that aren't readily available on a normal keyboard. While Alt codes don't exist on Mac computers, there are a variety of Option key shortcuts that can let you type the most popular characters. On Linux, you can press Ctrl + Shift + U to type any Unicode character, as long as the font you're typing it in supports it.
