How do I check if a string is a number (float)?

Question

What is the best possible way to check if a string can be represented as a number in Python? The function I currently have right now is: def is_number(s): try: float(s) return True except ValueError: return False Which, not only is ugly and slow, but also seems clunky. However, I haven't found a better method because calling float() in the main function is even worse.

In case you are looking for parsing (positive, unsigned) integers instead of floats, you can use the isdigit() function for string objects. >>> a = "03523" >>> a.isdigit() True >>> b = "963spam" >>> b.isdigit() False String Methods - isdigit(): Python2, Python3 There's also something on Unicode strings, which I'm not too familiar with Unicode - Is decimal/decimal
