ValueError: invalid literal for int() with base 10 is an error thrown when a string is passed to the int() function in python and it can’t be converted to an integer.
Reason of error
This error is thrown when a string is passed to int() function that is not a valid integer. This can happen when the string contains non-numeric characters or leading/trailing whitespace.
my_int = int("123abc")
Solution to solve issue
The best solution is to check the value of the string before passing it to int(). If the value is not a valid integer, a custom error message can be thrown. Alternatively, the string can be stripped of non-numeric characters or whitespace before passing it to int().
