How do I parse a string to a float or int

0 votes

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

I just want to know how to parse a float str to a float, and (separately) an int str to an int.

Hii,

Python method to check if a string is a float:

def is_float(value):
  try:
    float(value)
    return True
  except:
    return False

A longer and more accurate name for this function could be: is_convertible_to_float(value)

Thank You!!
