# Python, <strike>156</strike> 151

This was good fun to program, my first code golf!

 n=input()
 a=n-1
 b='/\\/ '*a
 c=r'\/\ '*a
 d='\n| '+b+'/\\ |\n| \\/ '+b+'|\n'
 print' __'*n+'\n '+'/ \\'*n+d+' \\ '+c+'\\/\n /\\ '+c+'\\'+d+' '+'\\__/'*n

save it in an external text editor as n.py in order to remove last newline character in order to get from 152 to 151 bytes, open and run the module, and call k(n).
