It is fun.the result of str.lower(str())

[Sullivan WxPyQtKinter]

Guess what would be the result of these functions:

str.lower('ASFA')
str.join(str(),['1','1','1'])
str.join('a','b')

If you guess them correctly, please explain.

as I just said, I.method() and C.method(I) are equivalent,
so that's just an odd way to write

'ASFA'.lower()
str().join(['1', '1', '1'])
'a'.join('b')

which, given that str() returns an empty string, and a string
behaves like a sequence of individual characters, is equivalent
to

'ASFA'.lower() => 'asfa'
''.join(['1', '1', '1']) => '111'
'a'.join(['b']) => 'b'

</F>

I think it was because I've read the manuals.

str.lower('ASFA')
=> 'ASFA'.lower() => 'asfa'
str.join(str(),['1','1','1'])
=> ''.join(['1','1','1']) => '111'
str.join('a','b')

=> 'a'.join('b') => 'b'

No need to guess, there's this thing named the python interactive shell,
you know... And it even has an integrated help system.
please explain.

Explain what ? It's all in the fine manual.

* Klass() is a call to Klass's constructor and returns an instance of Klass.

* Klass.method(klass_instance) is the same as klass_instance.method()
* str is the builtin string class.
* without any args, the str constructor returns an empty string
* str.join() takes a sequence of strings and join'em with the target str
instance as separator

Now would you be kind enough to explain what's funny about all this ?

Now would you be kind enough to explain what's funny about all this ?

I would guess it's the statement: "Funny, it works!"

Can you tell us what you expected these to do? It might help future
questioners.
