How does python convert a floating-point string with a decimal to an integer

Today, I would like to share with you how python converts floating-point strings with decimals into integers with detailed content and clear logic. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

The following is perfectly acceptable in python:

1. Pass the string representation of the integer to int

2. Pass the string representation of float to float

However, if you pass a float string to int, you will get an error.

> int ('5') 5 > float ('5') 5.0 > float ('5') 5.0 > int (5) > > float (5) 5.0 > int ('5.0') Traceback (most recent call last): File ", line 1, in ValueError: invalid literal for int () with base 10:' 5.0' > > int (float ('5.0'))

Add: solve the problem of floating point conversion of python string

ValueError: invalid literal for int () with base 10

Recovery error: str_a = '1.5'int_a = int (str_a) Correction error: # Correction method 1str_a =' 1.5'int_a = int (float (str_a)) # Correction method 2str_a = '1.5'int_a = int (eval (str_a)) error cause

Floating-point strings cannot be converted directly to int types
