如何使布尔表达式更短？或或或或

Question

var = raw_input()

if "0" in var or "1" in var or "2" in var or "3" in var or "4" in var or "5" in var or "6" in var or "7" in var or "8" in var or "9" in var:
    print "yay"
else:
    print: ":("

以某种方式在这里使用列表是否可能？

  print "yay"
else
  print ":("

甚至更短:

print "yay" if re.search(r"\d", str) else ":("
