如何编写将返回包含从文本文件加载的数据的字典的函数

Posted 2021-04-11

这是我到目前为止所拥有的，现在我没有定义sankey。

    def makeSankey (inf):

     sankey = {}
     with open("file.txt") as f:
         for line in f:
            (key, val) = line.split()
            sankey[str(key)] = val



     return makeSankey()

    for i in sankey():
     print(i),sankey[i]`

答案

def makeSankey (file):

 sankey = {}
 with open(file) as f:
     for line in f:
        (key, val) = line.split()
        sankey.update({str(key) : val})



 return sankey
file = # file path + name
sankey = makeSankey(file)
for k,v in sankey.items():
 print(k, v)

另一答案

如果file.txt包含类似key val的行，则此方法有效>

  def makeSankey (): 

      sankey = {} 
      with open("file.txt") as f: 
          for line in f: 
             (key, val) = line.split() 
             sankey[str(key)] = val 


      return sankey 

     for k,v in makeSankey().items(): 
        print(k,v)
