 straightforward: use the new() to create an md5 object. You can now\n\
 feed this object with arbitrary strings using the update() method, and\n\
 at any point you can ask it for the digest (a strong kind of 128-bit\n\
-checksum, a.k.a. ``fingerprint'') of the contatenation of the strings\n\
+checksum, a.k.a. ``fingerprint'') of the concatenation of the strings\n\
 fed to it so far using the digest() method.\n\
