How to decide whether a number in a dictionary is a str or float?

Question

I am asking this because I saw a dictionary produced from two different sources, in which one number is a float, and the same number is a string.

data = {'name': 'jack', 'confidence': '0.95'}

The 'confidence' is a float in once case, and a str in another case. Why is that?

conf = data.get('confidence')

because one source decided to give you strings, other decided to give you floats. I dont really see a question here. — Paritosh Singh, Jun 12 '19 at 17:07

It all depends on how they decided to store value in the dict. But if you want to access the value, conf = float(data.get('confidence')) might be good for your use.

Values in a dictionary surrounded by quotes are strings. '0.95' is a string, but 0.95 is a float. You can use the isinstance built-in function:

conf = data.get('confidence')
if isinstance(conf, str):
    pass
elif isinstance(conf, float):
    pass

conf = data.get('confidence')
try:
  conf = float(conf)
except:
  pass
