unfortunately there is no builtin function for this
>>> int("111",2)
7
>>> str(7)
'7'
>>> str(7,2)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: str() takes at most 1 argument (2 given)

int, str are not symmetrical
I hope this will change in future

you can use Ruby's 7.to_s(2) for this
irb(main):001:0> 7.to_s(2)
=> "111"
irb(main):002:0> 7.to_s(3)
=> "21"
irb(main):003:0>

you can use bitwise operations on int's anyway
7 & 3 == 3
(1 << 20) | (1 << 10) == 2**20+2**10
and so on
