invalid literal for int()

This error message is raised when you try to convert a value that cannot be interpreted as an integer using the int() function.

For example, if you try to convert a string that contains non-numeric characters to an integer, you will get this error.

Here's an example code snippet that will raise this error:

string_value = "abc"
int_value = int(string_value)

In this code, the string "abc" cannot be converted to an integer, so the int() function will raise the "invalid literal for int()" error.

To fix this error, make sure that the value you are trying to convert to an integer is a valid numeric value. You can use the isnumeric() method to check if a string contains only numeric characters before converting it to an integer.

Here's an updated version of the code that checks if the string is numeric before converting it to an integer:

string_value = "123"
if string_value.isnumeric():
    int_value = int(string_value)
else:
    print("Invalid numeric value")
