How do I parse a string to a float or int?

Question

In Python, how can I parse a numeric string like \"545.2222\" to its corresponding float value, 545.2222? Or parse the string \"31\" t

Pass your string to this function:

def string_to_number(str):
  if("." in str):
    try:
      res = float(str)
    except:
      res = str  
  elif(str.isdigit()):
    res = int(str)
  else:
    res = str
  return(res)

It will return int, float or string depending on what was passed.

string that is an int

print(type(string_to_number("124")))

string that is a float

print(type(string_to_number("12.4")))

string that is a string

print(type(string_to_number("hello")))

string that looks like a float

print(type(string_to_number("hel.lo")))
