Lua：字符串要命名吗？

Question

is it possible to convert a string into a name of a table entry? just like

string = "test"
y = {test = 123}
print y.string

So if string is "test" it would print y.test if there is such a entry
Hope you understand my question!
Thanks in advance...

Answer 1

print(y[string])

Be careful with using names such as string for variables, especially globals. You've just overwritten the string table.
