The Magik programming does not have an inherent enumerate method like Python, however, it would be trivial to make one:
_global enumerate << _iter _proc@enumerate(list) _local i << 0 _for x _over list.fast_elements() _loop _loopbody({i, x}) # use simple-vector as a tuple i +<< 1 _endloop _endproc
Please note that the Magik does support the tuple, however, the tuple cannot be assigned to a tuple variable directly.
# tuple assignment works, x is 1 and y is 2 (x, y) << (1, 2)
However, this does not:
a_tuple << (1, 2) # Can only have a tuple on the right hand side if there is one on the left hand side
We can use the simple vector or rope to act as a tuple anyway (Tuples are just immutable array/vectors)
Example usages:
_for a _over enumerate({'a', 'b', 'c'}) _loop print(a) _endloop _global data << rope.new_with('a', 'b', 'c', 'd') _for a _over enumerate(data) _loop print(a) _endloop
And you should expect the following in the Magik console.
simple_vector(1,2): 1 0 2 "a" simple_vector(1,2): 1 1 2 "b" simple_vector(1,2): 1 2 2 "c" simple_vector(1,2): 1 0 2 "a" simple_vector(1,2): 1 1 2 "b" simple_vector(1,2): 1 2 2 "c" simple_vector(1,2): 1 3 2 "d" True 0

hello and thanks a lot for your nice examples with Magik coding.
I tried to run them on Visual Studio Code
but a Magik compiler is missing.
Could you provide me
a compiler
for to execute your Magik codes ?
Thanks in advance
Hi, I think the Magik compiler is not open source, and you need to contact the GE Smallworld Sales team for a trial.
