Given a list of numbers, calculate their sum using a for loop. Output the sum after the loop

Question

x = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]
sum = 0
for n in x:
sum+=n
print(sum)

Answer 1

joanna Godfrey ,

i have no idea what problem you have , but this is your code with the correct indentation: (and it works!)

x = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]
sum = 0
for n in x:
sum+=n
print(sum)

to avoid trouble like this, it is recommend to use 4 spaces for indentation.

Answer 2

You also should put the print statement at the same indent level as the for loop line. That way it only prints once

joanna Godfrey read it ^^^

Answer 3

Try this

x = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]
sum = 0
for n in x:
sum+=n
print(sum)

make sure print (sum) do not to start on the same line with the sum += n
like so,
___________________
for n in x:
sum+=n
print(sum)

Answer 4

x = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]
sum = 0
for n in x: #taking list values to n iteratively.
sum=sum+n #adding n value to sum

print(sum) #its outside of loop so prints only once after loop completion.

joanna Godfrey

if you work with indexes like x[n] then use
for n in range(len(x) ) : instead of for n in x:

x = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]
sum = 0
for n in range(len(x)):
sum=sum+x[n]
print(sum)

Answer 5

x = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]
sum = 0
for n in x:
sum+=n
print(sum)

Why do you have to enter "sum = 0"?

And where did "n" come from?

Thx

Addendum: I at least understand that there is nothing special about the characters of "sum" or "n" in particular. . .

piglet = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]
bacon = 0
for oink in piglet:
bacon+=oink
print(bacon)

Answer 6

#Given a list of numbers, calculate their sum using a for loop. Output the sum after the loop

num = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]
sum=0
for x in num:
sum+=x
print(sum)

Answer 7

x = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]

S=0
for cal in x:
S+=cal
print(S)
===
Make sure you put Print and For Statment in the same level

Answer 8

Thank you

Answer 9

x = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]
sum = 0
for n in x:
sum=sum+x[n]
print(sum)
Still not working
