In the Code Coach Challenges the length of the input seems to be longer than the actual input.

Question

When i read the input in python using something like:
Word = input() or words = input().split()
The string named word or the last element in words is 1 longer than the actual word. This does not seem to be the case in the code playground.
Does anyone know why this is and how to avoid this?

Answer 1

You can use input().strip(), that removes any invisible whitespace like \n or \r at the edges and doesn't do harm if there wasn't any.

Answer 2

davy hermans yes it is the return carriage /r at the end of some strings. You can check this with a print of the string as your first output in Code Coach chalenge cases 1 and 2.

Answer 3

davy hermans I guess in Code Coach the input is automated hence the /r problem. I got the same issue.

Answer 4

HonFu
Just to wrap it up. You were right. I've confused strip with split from your first post. Second your code bit from your other post I was expecting to return chars one by one because I was inputing a string of only one word no space that is why I said it is not working.

davy hermans sorry for highjacking your post.

HonFu constructive discution, at least from my side, hope I didn't offend you in any way.

Answer 5

Mihai Apostol thanks for your answer.
I saw the /r but i wonder why i don't see this in the code playgound. Is it because of the way the input is presented?

Answer 6

HonFu thanks, that is exactly what i was looking for.

Answer 7

HonFu thou...check this two codes:

x = input()
for char in x:
print(char)

x = input().split()
for char in x:
print(char)

Answer 8

Mihai Apostol if i am right, the first one is a string, the second a list.

Answer 9

davy hermans it is the other way around. With the first one I was able to go through the chars one by one with the second I cannot.

Answer 10

HonFu just ran it in playground...not working...

Answer 11

HonFu a string

Answer 12

HonFu I know what it doesn't do. It is not going through the chars one by one.

Answer 13

You said:
"You can use input().strip(), that removes any invisible whitespace like \n or \r at the edges and doesn't do harm if there wasn't any."

I said:
"HonFu thou...check this two codes:

x = input()
for char in x:
print(char)

x = input().split()
for char in x:
print(char)"

You said that using split doesn't do any harm, I just said I cannot go through the string one char at a time.

It is on topic, as I was interesed to remove those \r at the end of some strings in code coach.

Answer 14

strip - not split - is what I said to be not doing any harm.

Split returns a list of strings, and strip only works with strings.

So you have to use strip on each word in the list - which my code example does.

What exactly is 'not working' with it? (I tried it - does just what I said.)

Answer 15

Hum..

Answer 16

Mihai Apostol,

x = input().split()
for word in x:
print(word.strip())

Answer 17

Mihai Apostol What did you input?

Answer 18

Do you understand what that piece of code is supposed to do?

Answer 19

It's not the point of these lines to do that, so it would be strange if they did.

What exactly do you want to know?

And has it a relation to this question? (If not, you should make a post of your own.)
