Built-in Functions

print(object = ‘’, end = "\n")
Print

object

to stdout followed by

end

.

input([prompt])
If the

prompt

argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that.

assert(expression, message = ‘’)
Raise AssertionError if

expression

evaluates to false.

exit(message = N)
Terminates the calling process. When

message

is specified it is printed to stderr.

sleep(secs)
Suspend execution of the calling thread for the given number of seconds. The argument may be a floating point number to indicate a more precise sleep time.

swap(&a, &b)
Exchanges the values of the two arguments. Equivalent to

(a, b) = (b, a)

.

zip(iterable1, iterable2 [,iterable3])
Aggregates elements from input iterables.

all(iterable)
Return true (1B) if all elements of the

iterable

are true (or if the

iterable

is empty).

any(iterable)
Return true (1B) if any element of the

iterable

is true. If the

iterable

is empty, return false (0B).

cart_product(iterable1, iterable2 [,iterable3])
Cartesian product of input iterables.

multiloop(iterable1, iterable2 [,iterable3], function)
This function is roughly equivalent to the following code: {…

F multiloop(iterable1, iterable2, function)
   V r = []
   L(el1) iterable1
      L(el2) iterable2
         r [+]= function(el1, el2)
   R r

}

multiloop_filtered(iterable1, iterable2 [,iterable3], filter_function, function)
This function is roughly equivalent to the following code: {…

F multiloop_filtered(iterable1, iterable2, filter_function, function)
   V r = []
   L(el1) iterable1
      L(el2) iterable2
         I filter_function(el1, el2)
            r [+]= function(el1, el2)
   R r

}

sum(iterable)
Sums the items of an

iterable

and returns the total.

product(iterable)
Multiplies the items of an

iterable

and returns the total.

sorted(iterable, key = N, reverse = 0B)
Return a new sorted array from the items in

iterable

.

key

specifies a function of one argument that is used to extract a comparison key from each element of

iterable

.

reverse

is a boolean value. If set to true (1B), then the elements of

iterable

are sorted as if each comparison were reversed.

min(arg1, arg2)
Return the smallest of two arguments.
min(iterable)
Return the smallest item of

iterable

.

max(arg1, arg2)
Return the largest of two arguments.
max(iterable)
Return the largest item of

iterable

.

hex(x)
Convert an integer number to an uppercase hexadecimal string.

bin(x)
Convert an integer number to a binary string.

rotl(value, shift)
Rotate the

value

left by

shift

bits.

rotr(value, shift)
Rotate the

value

right by

shift

bits.
