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

Question

How can someone parse a numeric string like "121.5555" to it's corresponding float value 121.5555? or parse a string like "21" to an integer 21?

So can someone tell me how to parse a float str to a float and an integer str to an int.

Answer 1

There are several methods to perform this task but I personally recommend you to use ast.literal_eval It's the safe eval method to perform, check following code to your problem:

>>> import ast
>>> ast.literal_eval("121.555")
545.2222
>>> ast.literal_eval("21")
31
