That's one very important aspect of functions, yes. But there's another:
If I'm writing a module that needs to fetch user details from an LDAP
server, it might be worthwhile to put all of the LDAP-specific code in
its own method, even if it's only used once. That way the main module
can just contain a line like this:
user_info = get_ldap_results("cn=john gordon,ou=people,dc=company,dc=com")
The main module keeps a high level of abstraction instead of descending
into dozens or even hundreds of lines of LDAP-specific code.
