[Section titled “rpartition”](https://dev.algorand.co/reference/algorand-python/api/api-algopyop/#rpartition)

_rpartition()_

Partition the string into three parts using the given separator.

This will search for the separator in the string, starting at the end. If
the separator is found, returns a 3-tuple containing the part before the
separator, the separator itself, and the part after it.

If the separator is not found, returns a 3-tuple containing two empty strings
and the original string.

character (including \n \r \t \f and spaces) and will discard

empty strings from the result.

_translate()_

Replace each character in the string using the given translation table.

table
Translation table, which must be a mapping of Unicode ordinals to
Unicode ordinals, strings, or None.

The table must implement lookup/indexing via **getitem**, for instance a
dictionary or list. If this operation raises LookupError, the character is
left untouched. Characters mapped to None are deleted.

for curve points A and B, return the curve point A + B
A and B are curve points in affine representation: field element X concatenated with field element Y. Field element `Z` is encoded as follows.
For the base field elements (Fp), `Z` is encoded as a big-endian number and must be lower than the field modulus.
For the quadratic field extension (Fp2), `Z` is encoded as the concatenation of the individual encoding of the coefficients. For an Fp2 element of the form `Z = Z0 + Z1 i`, where `i` is a formal quadratic non-residue, the encoding of Z is the concatenation of the encoding of `Z0` and `Z1` in this order. (`Z0` and `Z1` must be less than the field modulus).

The point at infinity is encoded as `(X,Y) = (0,0)`.
Groups G1 and G2 are denoted additively.

Fails if A or B is not in G.
A and/or B are allowed to be the point at infinity.
Does _not_ check if A and B are in the main prime-order subgroup.

maps field element A to group G
BN254 points are mapped by the SVDW map. BLS12-381 points are mapped by the SSWU map.
G1 element inputs are base field elements and G2 element inputs are quadratic field elements, with nearly the same encoding rules (for field elements) as defined in `ec_add`. There is one difference of encoding rule: G1 element inputs do not need to be 0-padded if they fit in less than 32 bytes for BN254 and less than 48 bytes for BLS12-381. (As usual, the empty byte array represents 0.) G2 elements inputs need to be always have the required size.

The name `ec_multi_scalar_mul` was chosen to reflect common usage, but a more consistent name would be `ec_multi_scalar_mul`. AVM values are limited to 4096 bytes, so `ec_multi_scalar_mul` is limited by the size of the points in the group being operated upon.

decode A which was base64-encoded using _encoding_ E. Fail if A is not base64 encoded with encoding E
_Warning_: Usage should be restricted to very rare use cases. In almost all cases, smart contracts should directly handle non-encoded byte-strings. This opcode should only be used in cases where base64 is the only available option, e.g. interoperability with a third-party that only signs base64 strings.

Decodes A using the base64 encoding E. Specify the encoding with an immediate arg either as URL and Filename Safe (`URLEncoding`) or Standard (`StdEncoding`). See [RFC 4648 sections 4 and 5](https://rfc-editor.org/rfc/rfc4648.html#section-4). It is assumed that the encoding ends with the exact number of `=` padding characters as required by the RFC. When padding occurs, any unused pad bits in the encoding must be set to zero or the decoding will fail. The special cases of `\n` and `\r` are allowed but completely ignored. An error will result when attempting to decode a string with a character that is not in the encoding alphabet or not one of `=`, `\r`, or `\n`.

Copy of (byte-array or integer) A, with the Bth bit set to (0 or 1) C. If B is greater than or equal to the bit length of the value (8\*byte length), the program fails
When A is a uint64, index 0 is the least significant bit. Setting bit 3 to 1 on the integer 0 yields 8, or 2^3. When A is a byte array, index 0 is the leftmost bit of the leftmost byte. Setting bits 0 through 11 to 1 in a 4-byte-array of 0s yields the byte array 0xfff00000. Setting bit 3 to 1 on the 1-byte-array 0x00 yields the byte array 0x10.
