how can I declare a variable with another variable *name?

how can i do it with no Arrays using *python
Others have given you the direct answer.
Well using locals() is the right answer, it is a very bad use case for eval.
But using lists or dicts is
almost always a better solution in Python than synthesizing global/local
namespace names.
a={'hello':'baybay'}
print a['hello']
But locals() *is* an already made dict, very convenient for use locally and
read-only.

locals()
a proper and easy use of locals with locals()
