Can someone please explain Assignment Operators/ In- Place Operators?!

I am completely confused on Assignment Operators ( Ex. X+=3) Can someone explain this as easily and understandable as possible? Here is a link to the lesson: https://www.sololearn.com/learn/JUMP_LINK__&&__Python__&&__JUMP_LINK/2429/. Any and all explanations welcome!

It is usually a reduced form of raising an expression. But it is better to see it with an example: # Declaration and assignment of a numeric variable. my_number = 5 # The next line is equivalent to saying something like "The value that is stored in the variable my_number plus 2" my_number = my_number + 2 # 5 + 2 = 7 This can be simplified by writing it in the following way: my_number + = 2 # 5 + 2 = 7 In the same way this works with the operations of addition, subtraction, multiplication and modulation of a division (- =, * =, / =,% =). In the same way with the variables type String can be used, but with a different behavior: # Declaration and assignment of a variable type string. my_string = "hello" # The following line is equivalent to saying "To the content that is stored in the variable my_string adds the string 'world' to the end" my_string = my_string + "world" #This is equivalent to my_string = "hello" + "world" And in the same way it can be simplified to: my_string + = "world" The strings can also be used like this: my_string = my_string * 2 #my_string = "hellohello" That is equivalent to saying "Repeat the code that is stored within the variable my_string x times" (in this case twice). And in the same way it can be reduced to: my_string * = 2 I hope my explanation does not cause you more confusion lol

Yeah. Keep in mind that the first example should be x = x + 8

So it is a basic variable just rearranged? Example: x=7 x+8. (=15) but instead: x=7 x+=8 (still amounts to 15)
