Hello

what I sometimes miss in Python is the possibility to
switch tha base of a number
for example this is how it's done in Ruby

irb(main):099:0* a = 10.to_s(2)
=> "1010"
irb(main):100:0> a.to_i(2)
=> 10
irb(main):101:0>
irb(main):102:0* a = 10.to_s(3)
=> "101"
irb(main):103:0> a.to_i(3)
=> 10

the Python int-Function behaves similar[color=blue][color=green][color=darkred]
>>> int("1010",2)[/color][/color][/color]
10[color=blue][color=green][color=darkred]
>>>[/color][/color][/color]

however we lack the reverse functionality
the logical
[color=blue][color=green][color=darkred]
>>> str(10,2)[/color][/color][/color]
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: str() takes at most 1 argument (2 given)[color=blue][color=green][color=darkred]
>>>[/color][/color][/color]

fails

it would not break anything if str interface would be changed
what do you think?
Is this already proposed or maybe implemented in 2.5?

Regards, Daniel

It's been proposed:

But it didn't look like there was a resolution.
