str() representation of sequences and dicts

[Kwikrick]

When calling str() on a sequence or dict object, the elements of the
sequence/dict will be represented as if their __repr__ method was
called. Why is this? Wouldn't it be more consistent when calling str()
on sequence to use the __str__ method of the elements in the sequence?

As it is now, I often find myself typing something like:

print map(str, alist)

instead of just

print str(alist)

For dicts, it's more eleborate still.

Is there a better way to deal with this?

Rick.

Dear All,

I want to know about Modules and packages.
I can understand about Modules but I cannot understand
about Packages. Kindly let me
know about Packages with small example.
I can understand conceptually but I don't know
how to write programmatically.

In your headers I see "In-Reply-To:

that people will see your message as part of another thread. It's better
not to do that if you want your message to be read in the proper context.

A package is simply a directory containing an __init__.py file, which is
executed when the package is imported. Sub-packages are subdirectories
of the package main directory containing __init__.py files, which will
be executed when the sub-package is imported. Packages can also contains
modules, which are regular Python files that are executed when the
module is imported.

So, in brief, packages are just a way to let you organize your code in
to a set of mutually dependent modules and sub-packages, making source
maintenance easier and allowing selective import of parts of the
implemented functionality.
