I've always laughed to myself when I've looked back at my VB6 days and thought, "What modern language doesn't allow incrementing with double plus signs?":
number++ To my surprise, I can't find anything about this in the Python docs. Must I really subject myself to number = number + 1? Don't people use the ++ / -- notation?

In Python these operators won't work. In Python variables are just labels to objects in memory. In Python numeric objects are immutable. Hence by a++ (if a=10) we are trying to increment value of 10 object to 11 which is not allowed.
i+=i means the i now adds its current value to its self so let's say i equals 10 using this += expression the value of i will now equal 20 because you just added 10 to its self. i+=1 does the same as i=i+1 there both incrementing the current value of i by 1. 3rd January 2020, 3:15 AM.
Sets cannot contain duplicates. Duplicates are discarded when initializing a set. If adding an element to a set, and that element is already contained in the set, then the set will not change.
Python while loop will check for the condition at the beginning of it. If the condition evaluates to True, then it will execute the code inside it. Next, we have to use Arithmetic Operator inside the Python while loop to increment and decrement the value. After the value increments, it will again check the expression.
Python doesn't support ++, but you can do:
number += 1 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
