simple question

Expand Post »

I'm just wondering what do I have to add to the code

print "Hello World"

to output

H e l l o W o r l d

like there's spaces in between each letter?

Thanks.

Re: simple question

You could do:

python Syntax (Toggle Plain Text)
for c in "Hello World":
    print c ,
for c in "Hello World":
    print c ,

In Python2 the comma puts in a space and keeps it on the same line.

Re: simple question

You could also try some string formatting. Check this out...

python Syntax (Toggle Plain Text)
text = 'Hello World'
for x in text:
    print x.rjust(2)
 
# output is  H  e  l  l  o     W  o  r  l  d
text = 'Hello World'
for x in text:
    print x.rjust(2)

# output is  H  e  l  l  o     W  o  r  l  d

Re: simple question

They're all trying to just confuse you.

Python Syntax (Toggle Plain Text)

print "H e l l o W o r l d"

Re: simple question

Well I assumed that the poster already knew that way to do it. Here's another way to do it. In all of the solutions except AutoPython's the output will contain three spaces in the middle, but the original post only has one space between the o and the w. Here is a way to do that programatically

python Syntax (Toggle Plain Text)
mystring = 'Hello World'
outstring = ''
 
for x in mystring:
   outstring += x
   if x != ' ':
      outstring += ' '
print outstring
mystring = 'Hello World'
outstring = ''

for x in mystring:
   outstring += x
   if x != ' ':
      outstring += ' '
print outstring

Jesus Christ guys, pythonic code is SUCCINCT ;-)

Python Syntax (Toggle Plain Text)
print ' '.join(list('Hello World'))
print ' '.join(list('Hello World'))

Re: simple question

I think Pythopian gets the award for most elegant code. That is just beautiful.

Re: simple question

Actually, if you temporarily flip to Reply with quote in the OP post you find out the request was for:

Python Syntax (Toggle Plain Text)

H e l l o  W o r l d

That is 2 spaces between 'o' and 'W', DaniWeb swallowed up the extra space since it was not in a code field. So the honor goes to mn_kthompson!

If you MUST have exactly two spaces...

... between "H e l l o" and "W o r l d":

Python Syntax (Toggle Plain Text)
print ' '.join(c if c != ' ' else '' for c in 'Hello World')
print ' '.join(c if c != ' ' else '' for c in 'Hello World')

To ensure exactly one space everywhere:

Python Syntax (Toggle Plain Text)
print ' '.join(c for c in 'Hello World' if c != ' ')
print ' '.join(c for c in 'Hello World' if c != ' ')
