Why would this be like this?

Question

Basically i understand most of this i made it to kind of practice amd further understand it but when i put a=a+4 why would it not add the original a = 2 and 4 and begin counting by 6?

Answer 1

a = 2 # a is 2

print(a+2) # a is 2 but it prints 4
a = a+4 # a is 2+4 so a is 6

print(a+2) # a is 6 but it prints 8
a = a+4 # a is 6+4 so a is 10

print(a+2) # a is 10 but it prints 12
a = a+4 # a is 10+4 so a is 14

Thanks for the Tick ✔ 👍

Answer 3

Can you tell us what sequence you want?
Do you want 2,4,6,8... or 4,8,12.. or 6,10,14...?

Answer 4

yea u made it pretty clear @Jafca. still have doubts @seth?

Answer 5

ah ok. honest mistake. we are here to help

Answer 6

"a" gets the value of a + 4. since "a" starts with 2, a gets the value of 2 + 4. so "a" gets the value of 6.
if u continue....
a=a+4 // a is 10
a=a+4 // a is 14
a=a+4 // a is 18

and so on

Answer 7

oh lol im not sure

Answer 8

oh

Answer 9

cause you are printing a + 2. change it to just print a

Answer 10

so you want to start at 4 and then count by 4s?

Answer 11

but if its already counting by 4s, i dont understand your problem

Answer 12

because then that would be counting by six. which means you would need a = a + 6.

Answer 13

omg im dumb, the a+4 part just means its going to add a by 4, saying a = a+4 through me off because i assumed it would add that 4 to the a and count by the new a. thanks tho

Answer 14

Yep thanks you guys!

Answer 15

no see thats what im saying if you run the code it still counts by 4s not 6s

Answer 16

but what if i want it to start at 4 without makimg a=4?

Answer 17

exactly BUT without changing a=2 to a=4

Answer 18

its not my problem, my problem is why doesnt a=a+4 not cause the original a to add with 4 and instead of counting by 4s count by 6s. sorry you kinda confused me, i want it to count by 4s and it does but why isnt it counting by 6s like it technically should. a+4 would be 2+4 which = 6 which means a would now = 6 therefore it shouldnt count by 4s anymore it should begin with 4 then continue to add with 6s.
