Add variable name to variable

Question

I have the following variable:

VarX=700

I now need to write the name of VarX into a txt file. So I'm thinking I need to create another variable and assign to it the name of VarX and then write it to a file. How can I assign a name of a variable to a variable?

Search for "python list tutorial" or "python dict tutorial", perhaps. There are some fundamental concepts that should be explored independently. — user2246674, May 03 '13 at 18:51

If you store your information as a dictionary:

variables = {'VarX': 700}

then you have access to the name and value without obfuscating your code.

So you have a value, and you want to associate it with a name. That's what we call a key/value pair, and in Python, you should use a dict (dictionary) to store that.

I recommend you use JSON format to save it to disk. You can put your key/value pairs into a dict, then save the whole dict to a JSON file. It's easy and reliable.
