What does Int A:: -1 mean in Python?
In Python, int (‘a’, -1) is not valid syntax. However, int (‘a’, -1) is not a valid expression.
But int (‘a’, 16) is valid. The second argument to the int function is the base of the number. For example, int (‘a’, 16) converts the hexadecimal number ‘a’ to an integer.
If you meant to ask about int (‘-1’), it means converting the string ‘-1’ to an integer. The result would be the integer -1.
If you’re asking about slicing, a [-1] means getting the last element of a sequence (like a list, tuple, or string). In Python, negative indices count from the end of the sequence. So, -1 refers to the last element, -2 refers to the second last element, and so on.
