somestring = "ABC" somestring2 = somestring + "D" somestring2 += "EF"
assert somestring2 == "ABCDEF"
assert somestring == "ABC"
assert id(somestring) != id(somestring2)
Basically, strings are immutable. If you need to append something to a
string, you need to construct a new string object with the new value.
Now if you are using this to collect huge outputfiles in pieces, one of
the common idioms in Python is collecting it in a list, and converting
to string at the end:
collector = []
for i in xrange(100000):
collector.append((str(i) * 80)[0:80])
string = "".join(collector)
assert len(string) == 8000000 # ~8MB
