When using ==, if the two items are the same, it will return True. Otherwise, it will return False. You can use = to assign values to variables.A variable created in the main body of the Python code is a global variable and belongs to the global scope. Global variables are available from within any scope, global and local. Example. A variable created outside of a function is global and can be used by anyone: x = 300. def myfunc ():The Python syntax is utilized such that underscores can be used as visual separators for digit grouping reasons to boost readability. This is a typical feature of most current languages and can aid in the readability of long literals, or literals whose value should clearly separated into portions.
