Italic

from sty import ef, fg, rs

a = ef.italic + "Italic." + rs.italic

# There are shorthands for this:
b = ef.i + fg.blue + "Italic." + rs.i + " Not italic but blue." + rs.fg

print(a, b, sep="\n")

Bold

from sty import ef, fg, rs

a = ef.bold + "Bold." + rs.bold_dim

# This has shorthands too:
b = ef.b + "Bold." + rs.bold_dim + fg.li_yellow + " Not bold but yellow." + rs.fg

print(a, b, sep="\n")

Underline

from sty import ef, fg, rs

a = ef.underl + "Underlined." + rs.underl

print(a, b, sep="\n")
