I would like to match the power value of a certain number using Regex: Exemple: A^2 --> num_pow = 2
power = "(\^[+-]?[1-9]\d*)"
num_pow1 = "(?P<num_pow1>" + power + ")"
num_pow2 = "(?P<num_pow2>" + power + ")"
currently this code will return "^2" rather than "2". I tried using "?:" without any sucess.
power = "\^([+-]?[1-9]\d*)"
num_pow1 = "(?P<num_pow1>" + power.group(1) + ")"
num_pow2 = "(?P<num_pow2>" + power.group(1) + ")"
