Question

我是新学习python的人，我必须处理该文件中的属性文件，该值将存在于键值对中，以及一些我认为设法读取文件但无法基于键存储或打印该值的方式

我尝试通过pip安装的jproperties库。我已经读取了对象中的值，但是无法从中获取记录。已访问https://pypi.org/project/jproperties/＃parsing-property-file网站以供参考

from jproperties import Properties

class PropertiesReader:
    p = Properties()
    with open("foobar.properties", "rt") as f:
        p.load(f, "utf-8")

    s = p.__getitem__("name","value")
    z = p.__getattribute__("email","mail")
    print(s)
    print(z)

和属性文件

foobar.properties
    name = Harsh
    email = abc.xyz

，输出为

Traceback (most recent call last):
  File "/home/harshk/PycharmProjects/demoPythonPOC/scratch.py", line 4, in <module>
    class PropertiesReader:
  File "/home/harshk/PycharmProjects/demoPythonPOC/scratch.py", line 7, in PropertiesReader
    p.load(f, "utf-8")
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 804, in load
    self._parse()
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 731, in _parse
    while self._parse_logical_line():
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 686, in _parse_logical_line
    self._skip_whitespace()
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 438, in _skip_whitespace
    c = self._peek()
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 378, in _peek
    c = self._source_file.read(1)
  File "/usr/local/lib/python3.7/codecs.py", line 500, in read
    data = self.bytebuffer + newdata
TypeError: can't concat str to bytes

Process finished with exit code 1

我想要打印

Harsh
abc.xyz

您正在打开文件，就好像它是文本文件一样：

    (function resize(){
    if (document.body.clientWidth<=640) {
      $('.quote-heading').readmore({
      speed: 75,
      lessLink: '<a href="#">Less</a>',
      moreLink:'<a href="#">Read more...</a>',
      collapsedHeight: 100,
      blockProcessed:function(element,collapsable){
          console.log(element);
      }
        });
    }
    if (document.body.clientWidth>640){
      $('.quote-heading').readmore('destroy');
    }
    })();

但是jproperties docs显示您需要以二进制模式打开文件：

with open("foobar.properties", "rt") as f:
    p.load(f, "utf-8")

测试以下代码：https://repl.it/repls/EmptyRowdyCategories

from jproperties import Properties

p = Properties()
with open("foobar.properties", "rb") as f:
    p.load(f, "utf-8")


print(p["name"].data)
print(p["email"].data)

我想从属性文件中读取并将该值放入基于文件
