如何分配名称是即时生成的python变量？

Question

Say I want to do the following:

name = 1.2

The thing is that the literal name of 'name' is provided on-the-fly (it could be 'mike=1.2', 'john=1.2',...)

Hope I explained my question, and thanks in advance for any hint.

Answer 1

You can use globals() or locals() depending on the scope needed:

>>> globals()['foo'] = 'bar'
>>> foo
'bar'

If you're asking this questions, however, it means you're doing something wrong - generating variables is essentially a bad idea. You should use structures such as a dictionary for this.

Answer 2

Here is an example of how to do this as a dictionary.

>>> people = {}
>>> people['mike'] = 1
>>> people['john'] = 2
>>> people['mike']
1
>>> people['john']
2
>>> print people
{'mike': 1, 'john': 2}

Also see the documentation here and here

Answer 3

you could do

globals()['yourvariables'] = variable

This adds the variable to the global namespace. I am not going to comment on whether it is a good idea or a bad one.
