method in python like eval() in javascript

Question

in javascript you can do:

i = -1;
array.forEach(function() {
 i++
 eval("var item" + i + " = " + array[0]);
});

to dynamically create variables, used this a couple of times to write data from an external JSON array into divs for each, is something like this possible in python(3.7)? especially the eval() method.

thanks in advance!

Yes, there is an eval function. But you shouldn't use it. You shouldn't use it in Javascript for this either. — juanpa.arrivillaga, May 22 '20 at 07:09

Yes there is! You can use the exec function in this case:

i = -1

for value in array:
    i += 1
    exec("item" + str(i) + " = " + str(array[0]))

There are negatives to this though, as stated in the comments already, but assuming you still decide to use it here it is.
