How do I add capital and lowercase letters to my current regex?

Question

I am currently using the findall regex to find and parse my equation such as this:

re.findall(r'\s*([\^.+*/-]|\d+)', evaluate)

what I tried to do is find letters among what I already found:

re.findall(r'\s*([a-zA-Z\^.+*/-]|\d+)', evaluate)
re.findall(r'\s*([a-zA-Z]|[\^.+*/-]|\d+)', evaluate)
re.findall(r'\s*([\^.+*/-]|\d+\w+)', evaluate)

Each one of these either gives errors or cuts off my operations and also did not give me my letters to parse. Second, I wanted to parse the letters how I parsed the numbers where 123 is one number, such as abc will be one section.

Currently: if I had 5*100+abc it'll parse like this:

['5', '*', '100', '+']

Any suggestions?

I should note that abc123 IS NOT one number. so putting just \w+ isn't a solution.

I want all abc's and numbers separated:

['123', 'abc'] or ['abc', '123']

And they should be separate like this \^ , . , + , * , / , - , 123 , abc
