Vector-like operations on python lists

Unique

• Unique, append

from rlike import *
x = [1, 2, 4, 3, 3]
append(x, [10, 11], 101)

[1, 2, 4, 3, 3, 10, 11, 101]

unique(x)

[1, 2, 3, 4]

Sets

• Set operations

x = [1, 2, 3, 3]
y = [3, 4, 6]
union(x, y)

[1, 2, 3, 4, 6]

setdiff(x, y)

[1, 2]

intersect(x, y)

[3]

• Checking a value among a set

x = [1, 2, 4, 3, 3]
y = [3, 4, 6]
match(x, y)

[None, None, 1, 0, 0]

match(y, x)

[3, 2, None]

match_arg('y', ['x', 'y', 'z'])

'y'
