how to write subscript and superscript in python
# function to convert to subscript
def get_sub(x):
normal = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+-=()"
sub_s = "ₐ₈CDₑբGₕᵢⱼₖₗₘₙₒₚQᵣₛₜᵤᵥwₓᵧZₐ♭꜀ᑯₑբ₉ₕᵢⱼₖₗₘₙₒₚ૧ᵣₛₜᵤᵥwₓᵧ₂₀₁₂₃₄₅₆₇₈₉₊₋₌₍₎"
res = x.maketrans(''.join(normal), ''.join(sub_s))
return x.translate(res)
# display subscript
print('H{}SO{}'.format(get_sub('2'),get_sub('4'))) #H₂SO₄
