如何检查字符串的空白或长度为零

Question

我最近问了一个关于将值列表从txt文件转换为字典列表的问题.你可以从这里的链接看到它:在这里查看我的问题

P883, Michael Smith, 1991

L672, Jane Collins, 1992

(added)
(empty line here)

L322, Randy Green, 1992

H732, Justin Wood, 1995(/added)

^key    ^name        ^year of birth 

===============
这个问题已经回答了,我使用了以下代码(接受的答案),它完美地运作:

def load(filename):
         students = {}


   infile = open(filename)
   for line in infile:
       line = line.strip()
       parts = [p.strip() for p in line.split(",")]
       students[parts[0]] = (parts[1], parts[2])
   return students 




 但是当txt文件的值中有一个行空间时(参见添加的部分)它不再起作用并且给出一个错误,说列表索引超出范围.

    

Answer 1

检查for循环中的空行并跳过它们:

for line in infile:
    line = line.strip()
    if not line:
        continue
    parts = [p.strip() for p in line.split(",")]
    students[parts[0]] = (parts[1], parts[2])
