Python strings have a .translate method:

# Example in Python 2
import string

# From top bit set...
from_chars = "".join(chr(c | 0x80) for c in range(0x7F))

# ...to top bit clear.
to_chars = "".join(chr(c) for c in range(0x7F))

# Build the translation table.
force_clear = string.maketrans(from_chars, to_chars)

s = "\x41\xC1"
print s
print s.translate(force_clear)
