EDIT2: (Thanks Padraic Cunningham)
This is the error I get when I try this in the interpreter,
>>> print s
Tony1
7684 dogs
Garry 2
8473 dogs
sara111
0 dogs
>>> spl = s.lstrip().splitlines()
>>>
>>> for it1, it2 in zip(spl[::2],spl[1::2]):
... print("{} {}".format(it1 ,it2))
...
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
ValueError: zero length field name in format
EDIT:
Im sorry this did not solve what I was looking for, I need to do this with words, for example my output on regex looks like:
Tony1
7684 dogs
Garry 2
8473 dogs
sara111
0 dogs
I need it to look like:
Tony1 7684 dogs
Garry 2 8473 dogs
sara111 0 dogs
Is this possible?
Original:
I would like to make several statements that give standard output without seeing newlines in between statements.
Specifically, suppose I have:
for item in range(1,100):
print item
The output looks like:
1
2
3
4
.
.
.
How get this to instead look like:
1 2
3 4
5 6
7 8
Using print item, item + 1
will not work on all data, zip will:
rn = range(1,100)
for item1,item2 in zip(rn[::2],rn[1::2]):
print item1,item2
Or izip_longest
for uneven length lists:
rn = range(1,100)
for item1,item2 in izip_longest(rn[::2],rn[1::2],fillvalue=0):
print item1,item2
rn[::2]
gets every second element starting from elemett 0, rn[1::2]
gets every second element starting from element 1
From your edit, what you seem to need is to concat every two lines together:
s ="""
In [1]: paste
s ="""
Tony1
7684 dogs
Garry 2
8473 dogs
sara111
0 dogs
"""
spl = s.lstrip().splitlines()
for it1, it2 in zip(spl[::2],spl[1::2]):
print("{} {}".format(it1 ,it2))
## -- End pasted text --
Tony1 7684 dogs
Garry 2 8473 dogs
sara111 0 dogs
For python 2.6:
for it1, it2 in zip(spl[::2],spl[1::2]):
print("{0} {1}".format(it1 ,it2))
for item in range(1,100):
if item % 2 == 0:
print item
else:
print item,
from the ipython
shell
In [13]: def print_by(l,n):

It works because the list on which zip
operates contains n
instances of the same iterator on the argument list...
