What happens if a string cannot be converted to an integer using the int() function in Python?

If a string cannot be converted to an integer using the int() function in Python, a ValueError exception is raised. This typically occurs when the string contains non-numeric characters or is formatted in a way that cannot be interpreted as an integer.

Example:

string_value = "abc"  # Non-numeric string

try:
    integer_value = int(string_value)
except ValueError as e:
    print(f"Error: {e}")  # Output: Error: invalid literal for int() with base 10: 'abc'

Summary:

When attempting to convert a non-convertible string to an integer using int(), a ValueError is raised, indicating that the string does not represent a valid integer.
