Since pythons list comprehensions<\/code> are turing complete and require no line breaks, any<\/em> program can be written as a python oneliner.<\/p>\n

If you enforce arbitrary restrictions (like “order of the statements” – what does that even mean? Execution order? First apperarance in sourcecode?), then the answer is: you can eliminate some<\/em> linebreaks, but not all.<\/p>\n

instead of<\/p>\n

if x:\n   do_stuff()\n<\/code><\/pre>\n
you can do:<\/p>\n
if x: do_stuff()\n<\/code><\/pre>\n
instead of<\/p>\n
x = 23\ny = 42\n<\/code><\/pre>\n
you can do:<\/p>\n
x,y = 23, 42\n<\/code><\/pre>\n
and instead of <\/p>\n
 do_stuff()\n do_more_stuff()\n<\/code><\/pre>\n
you can do<\/p>\n
do_stuff; do_more_stuff()\n<\/code><\/pre>\n
And if you really, really have to<\/em>, you can exec<\/code> a multi-line python program in one line, so your program becomes something like:<\/p>\n
exec('''t=int(input())\\nwhile t:\\n t-=1;n=int(input());a=i=0\\n while not(n&1<<i):i+=1\\n while n&1<<i:n^=1<<i;a=a*2+1;i+=1\\n print(n^1<<i)+a\/2\\n''')\n<\/code><\/pre>\n
But if you do this in “real” code, e.g. not just for fun, kittens die.<\/p>\n<\/p><\/div>\n
