the better way to write it is the next x = 5 x += 3 is the same to x = x + 3 print(x)

X = 2 X+=3(it means X = X +3, X = 2 + 3, X = 5)

I'll try to explain it: As these both are same x = x + 3(it will add 3 to x and assign the new value to variable x thus overwrite s it with the new value. It is because python first performs operation on the right side of assignment operator(=) and then initialize the final value to the variable.) Now : x += 3( it will take x on both sides of assignment operator (=) then takes the operational operator(which in this case is +) and performs desired operation on right side first and then initialize it's value to the variable on left side)

X=2 is assigning the value of 2 to the variable X.. The next line is adding 3 to the variable X. Since X is = 2, adding 3 to it makes 5.

X+=3 It simply means X=X+3

Your code: X=2 X=X+3 print(X) Console: 1)X:2 2)now X:5 3)show X(5) to user

This operator is called as compound assignment operator , it increases the readability of the code. This operator adds the value with the variable which is on the LHS which is nothing but x = x +3

Here first the value of X is assigning with the value 2. The next line it is in assignment operator (eg:X+=2 i.e X=X+2) so,X is 2 ,adding 3 to it so the answer is 5 then print the X valuee

X += 3 Is the same as X = X + 3 Same goes for other operators Eg. x %= 3 ( same as x = x % 3) We already know that x = 2 So using x += 3 will give same output as x = x + 3 Which is x = 2 + 3 = 5.

I hope that my explanation would help here. So the in-place operators makes your code more simple, short and faster when executed. So for example >>> x = 1 print (x) #This gives us a value of 1. Assuming we want to increase the value of x by any integer n. We would normally write: x = x + n. If our integer is 1, we would have x = x + 1 which is the same as x+= 1. + means increment, and the increment is by the value after the '=' sign. We can increase, decrease, multiply and divide by any integer we want. And lastly, the value of x becomes the new value after x was increased in our example. So the new value of x becomes 2.

The first line assigns the value of x to 2. The next line adds on 3 to the existing value, with '+=', and 5 is printed out as that is the current value of x. Similarly, writing X = 2 and then X = X + 3 would give the same value. X should be in lowercase, capital letters are used for variables that do not change.

It fist makes the variable X with the number 2 And then it changes it but as you can see there is a + sign so it means it will add the older X variable with the new X variable So 2+3=5 And if you want you can change it from plus to any operation you want

IN PLACE OPERATORS Inplace operation is an operation that changes the content of a given algebra directly. That is, it changes in a single line without making a copy.
