python coding contest

[Mark Dickinson]

Here's a variant of André's brilliant idea that's
119 characters long, and fully printable:

j=''.join;seven_seg=lambda z:j(j(' _ | |_ _|_|'
[ord('^r|=Zm.:v\r'[int(a)])%u*2:][:3]for a in z)
+"\n"for u in(3,7,8))

Here's a variant of André's brilliant idea that's
119 characters long, and fully printable:

j=''.join;seven_seg=lambda z:j(j(' _ | |_ _|_|'
[ord('^r|=Zm.:v\r'[int(a)])%u*2:][:3]for a in z)
+"\n"for u in(3,7,8))

You have an escaped CR (\r) as the last character in your string.

Here is a 118 character fully printable variant without the \r:

j=''.join;seven_seg=lambda x:j(j(' _ |_|_ _|
|'[ord('^rm=3|4:s»'[int(c)])%d*2:][:3]for c in x)+"\n"for d in(3,8,7))

Note that there is only one non-ascii character in the code.

However, André's final solution is one character shorter (117).

j=''.join;seven_seg=lambda z:j(j(' _ | |_ _|_|'
[ord('^r|=Zm.:v\r'[int(a)])%u*2:][:3]for a in z)
+"\n"for u in(3,7,8))

You have an escaped CR (\r) as the last character in your string.

Which is perfectly printable.

Here is a 118 character fully printable variant without the \r:

j=''.join;seven_seg=lambda x:j(j(' _ |_|_ _|
|'[ord('^rm=3|4:s»'[int(c)])%d*2:][:3]for c in x)+"\n"for d in(3,8,7))

Note that there is only one non-ascii character in the code.

Which isn't. So I'm not sure what the point is you're trying to make.

Duh, sorry, it's early. 118 is better than 119. Printable or not
Still, a 119 bytes version that is fully printable is pretty cool.

No, you're right, I also somehow missed the point. I believed "»" to be
"printable" (opposed to control char's) but technically speaking, the
consensus is that "printable" restricts to 7-bit-ascii (in Python,
string.printable does not even change if you change the locale setting,
contrary to string.letters; this is a bit unclear in the Python docs).

Mark's point was that his solution was purely 7-bit-ascii printable and
as such it was good although it was one byte more.

In the next contest, there should be subcategories for solutions that
are 7-bit-printable and/or have no imports.
