Question

如何从CSV文件导入数据并逐行将其转换为字符串？每当我尝试时，都会收到错误消息，表明它仍然是列表或列表列表。我试图复制Netlogo用户手册中给出的示例，用于读取每个刻度线一行的文件（见下文）。我创建了一个更简单的例子。谢谢！

我的代码：

extensions [CSV]
globals [date]


to setup
  clear-all
  file-close-all
  file-open "S&PDate.csv"
  set date current-date
  reset-ticks
end

to go
  if file-at-end? [stop]
  set date current-date
  tick
end

to-report current-date 
  file-open "S&PDate.csv"
  let result csv:from-row file-read-line 
  while [ not file-at-end? ] [
    let row csv:from-row file-read-line
    set result (map result row)
  ]
  file-close
  report result
end

Saad is right, and you may want to have a look at the asking guidelines on making an MCVE. Are you wanting string output so that your monitors look nice? If so, would this do the trick?

extensions [ csv ]
globals [ dates ]

to setup
  ca
  set dates csv:from-file "example_strings.csv"
  reset-ticks
end

to go
  if ticks < length dates [
    print current-date
    tick
  ]  
end

to-report current-date
  report csv:to-string ( list item ticks dates )
end
