string - Python stdin, readlines. change output order -

i working mac , have question python look. using .txt file called rectangle.txt , within file looks this:

abcde fghij klmno

i need read these in using stdin. need programme to:

afk bgl chm din ejo

so far, have programme reads lines , splits them , prints them out. code edited

so when changed code this: line in sys.stdin.readline(): ls1 = line print ls1

i received list:

a b c d e

so need loop through other ones, can't figure out

i running function command line:

python rectangle.py < rectangle.txt

i trying larn of this, instead of giving me answer, help explain me, in way can understand.

also, in add-on .txt file input. programme test these inputs:

123 456 789

and

a b c

all doing same thing above. give thanks 1 time again in advance helping me. have been working on hours , can't seem figure out.

i'm assuming input in each line has same length.

in case have list of input strings , length of 1 of these strings loop.

["abcde", "fghij", "kilmn"] here here notice pattern of first character each string? "a" + "f" + "k".
