# Simple for loop example

Hi this is a simple for loop example I have no idea how to approach. I only know while, len functions (not count or sum in python yet) how can I solve? When This is code I'm given: #for loops allow you to easily iterate through lists. #Given a list of numbers, output their sum. #Sample Input #1 3 7 5 #Sample Output #16 list = [1, 2, 3, 4, 5, 6, 7, 8, 9] sum = 0 #your code goes here for x in list: if(x == 1): sum += 1 print(sum)

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

Thank you Jan I will study that

this is 100% correct
list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
sum = 0
#your code goes here
for i in list:
sum+=i
print(sum)

Fast Why are you checking x == 1 when you just need to add values of list?
Just do sum += x

+ 1

So far my code is:
sum = 0
for x in list:
sum += x
print(sum)
Is this what is happening?
Sum = 0+1
Sum = 1+2
Sum = 3+3
Sum = 6+4
Sum = 10+5
Sum = 15+6
Sum = 21+7
Sum = 28+8
Sum = 36+9
Sum = 45

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

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

This is a code playground beginner challenge i don't know what print(f'sum is {s}') yet

Fast Yes
Here we are adding next value with previous total value.

Try
list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
sum = 0
#your code goes here
for x in list:
if(x == 1):
sum += 45
print(sum)

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

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

list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
#0 is the first member
sum = 0
#do for all members in list
for l in list:
#next sumation is equal sum of last sum plus next one
#sum of member = member0 + next member
sum=sum+l
#you may use sum+=1 as well
print(sum)
#your code goes here

list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
sum = 0
#your code goes here
for i in list:
sum+=i
print(sum)

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

list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
sum = 0
#Sample Input 1 3 7 5
for x in list:
if x%2 == 1:
sum += x
elif x == 8:
break
print(sum)
#Sample Output 16

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

using sum() function:
list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
total = sum(list)
print(total)
