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.

In Python, you can convert a string str to an integer int and a floating point number float with int() and float() . This article describes the following contents. Use str() to convert an integer or floating point number to a string. You can also convert a list of strings to a list of numbers.
We can convert a string to float in Python using the float() function. This is a built-in function used to convert an object to a floating point number. Internally, the float() function calls specified object __float__() function.
Use Integer.parseInt() to Convert a String to an Integer This method returns the string as a primitive type int. If the string does not contain a valid integer then it will throw a NumberFormatException.
>>> a = "545.2222" >>> float(a) 545.22220000000004 >>> int(float(a)) 545 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
