Question

detect_rack_handler'     from
  \\..gem/ruby/1.8/gems/sinatra-1.4.6/lib/sinatra/base.rb:1437:in

请帮忙！

顺便说一句，使用building = [["Farm","-1","0","F","1","1","-1"], ["Plot","0","0","P","1","0","-1"], ["House","20","4","H","0","0","5"]] cmd = input(">") if (cmd == "build"): c = 0 length = len(building) while (c < length): bu = building(c) print(c + ") " + bu[0]) c = c + 1我得到：

e = sys.exc_info()

Answer 1

这里有固定代码：

building = [ ["Farm","-1","0","F","1","1","-1"], ["Plot","0","0","P","1","0","-1"], ["House","20","4","H","0","0","5"]]
cmd = input(">")

if (cmd == "build"):
      c = 0
      length = len(building)
      while (c < length):
            bu = building[c]
            print(str(c) + ") " + bu[0])
            c = c + 1

修复了什么：
- 缩进
- 调用列表构建 - （）而不是[]
- str（c）in print，因为c是int而你不能求和和

此外，import sys在使用e = sys.exc_info()
