Question

print(r'The conversion factor from z to $\eta$ is %a' %round(n,4))

Answer 1

There are a number of eta characters . You can print them using their names from the unicode standard:

import unicodedata as ud

>>> for eta in etas:
...     print(eta, ud.lookup(eta))
... 
GREEK CAPITAL LETTER ETA Η
GREEK SMALL LETTER ETA η
GREEK CAPITAL LETTER ETA Η
GREEK SMALL LETTER ETA η
MATHEMATICAL BOLD CAPITAL ETA 𝚮
MATHEMATICAL BOLD SMALL ETA 𝛈
MATHEMATICAL ITALIC CAPITAL ETA 𝛨
MATHEMATICAL ITALIC SMALL ETA 𝜂
MATHEMATICAL BOLD ITALIC CAPITAL ETA 𝜢
MATHEMATICAL BOLD ITALIC SMALL ETA 𝜼

Or by escaping their names like this: \\N{NAME} :

>>> print('\N{GREEK CAPITAL LETTER ETA}')
Η

Or using unicode hex escape sequences, like this:

>>> print('GREEK CAPITAL LETTER ETA \u0397')
GREEK CAPITAL LETTER ETA Η

>>> print('GREEK MATHEMATICAL BOLD CAPITAL ETA \U0001d6ae')
GREEK MATHEMATICAL BOLD CAPITAL ETA 𝚮
