Question

Can someone tell me why this code doesn't work and how to fix it

Answer 1

b=0
while 1:
b=int
a=float(input())
b=float(b)+float(a)
print(b)

# in the first line of the while loop, you try to assign 'b' variable with value of 'int', wich is not previously declared

Answer 2

Before the loop you assign 0 to 'b', but first line of loop, you try to assign the value of 'int' to 'b'...

Answer 3

So, you must write:

b = int(b);

Answer 4

In javascript the semi-colon is often not mandatory, but it's a good practice to use it where it should go, to avoid unwanted bugs due to the way the interpreter will try to add them for you ^^

Example:

function test() {
return
42
}

You could think that's a valid code, and in a way, it is... but if you call it, it will return 'undefined' because interpreter will add a semi-colon after the return statement ;P

Answer 5

Your code is:

b=0
while 1:
a=float(input())
b=float(b)+float(a)
print(b)

This will do an infinite loop calling the print API of the browser (to output at a printer)...
You need to rather use alert() function, and have a base case to end your loop ^^

Answer 6

My half-bad:

print() is the right function to use in Python context (I was confusing with another thread about JS), but you must have a base case anyway ;)

Answer 7

n = 3
b = 0
while 1:
a=float(input())
b=float(b)+float(a)
print(b)
n -= 1
if n == 0:
break

# more than one space for indentation improve readability ;)

Answer 8

n -= 1

# is equivalent to:

n = n-1

Answer 9

That's the goal ^^
If you keep your loop infinite, it will not work in code playground ;)

Answer 10

Assign 1000 to n, so the loop will run 1000 times...
But in sololearn code playground, you will need to input all 1000 expected values at once, each at a new line in the prompt box opened when you run the code (and with 1000 numbers, you'll probably get a time limit reached error in code playground ^^)

Answer 11

# If you don't know the number of input, you can do something like:

b = 0
while 1:
try:
a=input()
except:
a=''
if a == '':
break
a=float(a)
b=float(b)+float(a)
print(b)

# so the loop will break when you enter an empty input, as well as in code playground when there's no more line available in the sololearn main input (on EOF error)

Answer 12

I've edited my previous post about 'parseInt()' with 'int()': I still was confusing between JS and Python ;)

Answer 13

But i put before the loop that it = 0

Answer 14

No im trying to make it a integer

Answer 15

This isnt java so do i need the ;

Answer 16

I think i got it

Answer 18

The problem is it adds everything weird

Answer 19

I think thats sl's fault not py

Answer 20

Can you explain how to do that and it works now it just creates an error at the end
