the entire file is executable code, so Python runs the file when it's loaded to process any top-level class or function definitions. If a breakpoint is set, you might find the debugger breaking part-way through a class declaration. This behavior is correct, even though it's sometimes surp...
Array declaration To declare an"array"in Python, we can follow following syntax: array_name = array_alias_name.array(type_code, elements) Here, array_nameis the name of the array. array_alias_nameis the name of an alias - which we define importing the"array module". ...
You can also use Python type hints in your function declaration, as shown in the following example: fromtypingimportDict,Anydeflambda_handler(event:Dict[str,Any], context:Any) ->Dict[str,Any]: To use specific AWS typing for events generated by other AWS services and for the context object...
A slice of bytearray is also a bytearray. Note The fact that my_bytes[0] retrieves an int but my_bytes[:1] returns a bytes object of length 1 should not be surprising. The only sequence type where s[0] == s[:1] is the str type. Although practical, this behavior of str is ...
