table data

[compsystems]

Hello,
Python has an object type called DICTIONARY that in xcas / hpprime is table(), but python, only manages a few types of data in relation to xcas, which can operate with many more and powerfull math types.

Examples of use

PHP Code:

tblA := table( "float_1" = 5.0 , "integer_2" = 5, "complex_4" = 3+4*i, "identifier_6" = var01, "list_7" = [9,[8,7],[6,5,4]],   "symbolic_8" = x+y*i , "rational_9" = 3/4,  "string_12" = "Hello",  "set_2" = set[ a, b ,a, c ],  "polynomial_10" = poly1[ 1, -6, 11, -6 ] , "matrix" = [[1,2],[3,4]], "vector" = [9,8,7,6,5,4], "function_13" = f(x):=x+1  )
[enter] returns
table( … )
