You can find all of those operators in the Python language reference, though you'll have to scroll around a bit to find them all. As other answers have said:
- The
**operator does exponentiation.a ** bisaraised to thebpower. The same**symbol is also used in function argument and calling notations, with a different meaning (passing and receiving arbitrary keyword arguments). - The
^operator does a binary xor.a ^ bwill return a value with only the bits set inaor inbbut not both. This one is simple! - The
%operator is mostly to find the modulus of two integers.a % breturns the remainder after dividingabyb. Unlike the modulus operators in some other programming languages (such as C), in Python a modulus it will have the same sign asb, rather than the same sign asa. The same operator is also used for the "old" style of string formatting, soa % bcan return a string ifais a format string andbis a value (or tuple of values) which can be inserted intoa. - The
//operator does Python's version of integer division. Python's integer division is not exactly the same as the integer division offered by some other languages (like C), since it rounds towards negative infinity, rather than towards zero. Together with the modulus operator, you can say thata == (a // b)*b + (a % b). In Python 2, floor division is the default behavior when you divide two integers (using the normal division operator/). Since this can be unexpected (especially when you're not picky about what types of numbers you get as arguments to a function), Python 3 has changed to make "true" (floating point) division the norm for division that would be rounded off otherwise, and it will do "floor" division only when explicitly requested. (You can also get the new behavior in Python 2 by puttingfrom __future__ import divisionat the top of your files. I strongly recommend it!)

what is the purpose of number //= 10?
Thanks

number //= 10 is same as number = number // 10 And // operator is integer division ... which is pretty much division that discards the decimal part. 3 / 2 = 1.5 3 // 2 = 1 Using // operator with number 10 is usually used to remove right most digit. 195 / 10 = 19.5 195 // 10 = 19

x //= 2 is the same as doing this: import math x = 9 x = math.floor(x / 2) Which, x, in this case would be 4.

According to the Python Language Reference, in is a keyword . It accomplishes one of two things, depending on context. The first is that it checks if a value is in an iterable as part of a conditional statement: if 3 in [1, 2, 3]: print("3 is in this list") The second is that it iterates over an iterable and executes code for each element in that iterable as part of a for loop or list comprehension: numbers = [1, 2, 3] for i in numbers: print(i) doubled_numbers = [i * 2 for i in numbers]

In short, () means you’re calling a function that does something, [] means you’re grabbing something out of a sequence, and . means you’re accessing an attribute (which could be data, a function, etc.) attached to an object.

The short answer (this is a really good question, BTW) is that these are operators. That is, they're special symbols - like + or ~ - that tell the interpreter to perform some operation. To do something. The way that a statement like 2 + 2 is turned into the value 4 is called evaluation, and Python is trying to evaluate the lines of code you write, unless they're special statements (usually related to the flow of control through your program.) The () calling operator is an operator that means "the preceding value is a callable function; call it and evaluate to its return value." So in the same way that 2 + 2 reduces or simplifies to 4, print("hw") reduces or evaluates to that function's return value (which, for print, is None.) As a side effect, print also writes its argument to the console. That's actually the useful part, of course. Operators can come at different parts of the expression and we classify them with names related to that. + is an infix operator, because it appears in between its operands (the numbers it's going to add.) . is also an infix operator, because it appears between the name being looked up (on the right) and the namespace that name is being looked up in (on the left.) () comes at the end of the expression, so it's a postfix operator, and an operator like ~ or not comes before its operand, so we call it a prefix operator.

In that example it indicates that the statement is continued on the next line. But it can be hard to see when reading code, so it isn't recommended. A better approach is to use enclosing parentheses or brackets around the newline. Python will not error on an incomplete statement if there are still unclosed parentheses/brackets and will continue on the next line. If the line you want to break contains parentheses/brackets just use them, but you can add an extra set of parentheses if necessary, like this: return ("color: " + self.__color + " and filled: " + str(self.__filled))

It's escaping out the newline at the end of the line, so Python just sees it as more whitespace. As always, consider using variable assignment, different constructions, and parens to avoid having to do it in the first place. def __str__(self): return f"color: {self.__color} and filled: {self.__filled}"

It's an annotation that describes what that function will return. In more strongly typed languages, functions have to specify exactly what they will return (like an integer, a string, or a specific class of object), but Python lets us be sloppy and return whatever. This type annotation that was added a while ago allows us to specify what each function will return, but it's just an annotation. Python isn't a compiled language so you can still be sloppy and return 1 in a function that is annotated to return None. These features were added to enable better error finding using "linters" which analyze your code to find potential problems. So if you have a function which says it will return a str based on the annotation but you do something like x = the_function() + 1, a linter may be able to see that you're trying to add 1 to the return value of a function that claims to return a string.

It's the type returned by the method.

In Python, the '|' operator is defined by default on integer types and set types.
If the two operands are integers, then it will perform a bitwise or, which is a mathematical operation.
If the two operands are set types, the '|' operator will return the union of two sets.
a = set([1,2,3])
b = set([2,3,4])
c = a|b # = set([1,2,3,4])
Additionally, authors may define operator behavior for custom types, so if something.property is a user-defined object, you should check that class definition for an __or__() method, which will then define the behavior in your code sample.
So, it's impossible to give you a precise answer without knowing the data types for the two operands, but usually it will be a bitwise or.
