Are there any canned Python methods to convert an Integer (or Long) into a binary string in Python?

There is a myriad of dec2bin() functions out on Google... But I was hoping I could use a built-in function/library.

There are many ways to convert Python int to Binary String some of the important methods I am discussing here:-

The first method you can use is Python's string format method it can take a format spec:-

>>> "{0:b}".format(37)

As you have asked for  bin() which is an equivalent to hex(), it was added in Python 2.6 so below is an example that illustrates the use of bin() with long value:-

>>>bin(1065587585875875875)
