Printing the exponent in scientific numbers with superscript characters

The issue with the superscript numbers is that the UTF-8 codes are not contiguous, you need a translation table.

Here is one way to do it with the help of f-strings:

def scientific_superscript(num, digits=2):
    base, exponent = f'{num:.{digits}e}'.split('e')
    d = dict(zip('-+0123456789','⁻⁺⁰¹²³⁴⁵⁶⁷⁸⁹'))
    return f'{base}⋅10{"".join(d.get(x, x) for x in  exponent)}'

scientific_superscript(1.1884423896339773e-06)
# '1.19⋅10⁻⁰⁶'

scientific_superscript(3.141e123)
# '3.14⋅10⁺¹²³'

blacklisting characters:

example for 0 and +

def scientific_superscript(num, digits=2):
    base, exponent = f'{num:.{digits}e}'.split('e')
    d = dict(zip('-+0123456789','⁻⁺⁰¹²³⁴⁵⁶⁷⁸⁹'))
    return f'{base}⋅10{"".join(d.get(x, x) for x in exponent.lstrip("0+"))}'

scientific_superscript(3.141e3)
# '3.14⋅10³'

scientific_superscript(1e103)
# '1.00⋅10¹⁰³'
