Python - White Spaces

I've made a program as follows:

x = input('Message? ')
x = x[::3]
for i in x:
  print(i, end=' ')

it's supposed to give me the letters of input (every third letter) which it does, although it also prints a white space at the end which I have been unable to get rid of. I've tried everything including the .rstrip and [:-1] with no luck

Try this:

x = input('Message? ')
x = x[::3]
print(' '.join(x[::3]))

join lets you put a space between adjacent characters, leaving out the trailing white-space

You are telling print() to print that whitespace with end=' '.

Instead of calling print() repeatedly, pass in the whole list in one go:

print(*x)

Now each element of x is printed as a separate argument, using the default 1-space separator, and a newline as end.

Outside of passing in the elements as separate arguments to print(), you can also use str.join() to build one string with separators; this does require that all elements in x are strings or you'd need to explicitly convert them:

print(' '.join(x))
