I am trying to make a simple loop where it prints the output numbers 0-9 on separate lines. What am I doing wrong? I have looked at the examples on here and they don't really help me. If you could explain where I went wrong that would be very helpful.
def singleline(item):
number = 0
while number < 10:
print(number)
number = number + 1
You've defined a function but you haven't called it. Just add
singleline(1)
to the end of the script.
Try using a for loop with range.
for num in range(10):
print(num)
This is more concise than using a while loop.
Also, if you are using a while loop, I would recommend using number+=1. It is the same as number=number+1, but just looks cleaner.
Firstly remember to call the function at the end of your otherwise you have just executed it singleline(). Also you haven't used the item you put into the parameters.
A better way to write this using a while loop would be. def singleline(): num = 0 while num < 10: print(num) num += num The += just means add one to of the variable on the left to the variable on the right. For example a = 1 b = 2 a += b a would not equal 3 because it adds b to it's original value. However if you wanted something more efficient you could use this: for num in range(10): print(num) for loops work in the same way as a while loop (take a condition and do content until stopped) but does it for the amount of times set. So in simple terms all this code means is print num plus 1.
