I doubt the if increases the speed. The following is a bit improved
version:
# Original data:
data = 'asdfbasdf'
find = (('a', 'f'), ('s', 'g'), ('x', 'y'))
# The code:
data2 = data
for pat,rep in find:
data2 = data.replace(pat, rep)
print data2
# If find contains only chars, and the string is long
# enough, then this is more or less the faster solution:
from string import maketrans
table = map(chr, xrange(256))
for c1,c2 in find:
table[ord(c1)] = c2
table_str = "".join(table)
print data.translate(table_str)
