在一行中,我们使用get_payload()方法提取消息正文内容,并使用quopri.decodestring()函数解码 QP 编码的数据。然后,我们检查数据是否有字符集,如果我们确定了字符集,则在指定字符集的同时使用decode()方法对内容进行解码。如果编码是未知的,我们将尝试使用 UTF8 对对象进行解码,这是在将decode()方法留空时的默认值,...

parseString(sourceString, parseAll=False):在整体匹配模式下仅调用一次;返回一个ParseResults对象;如果parseAll设置为True,则如果语法未处理完整的输入字符串,则parseString将引发ParseException。从定义上看,如果这个文本可以应用多次规则也只会运用到第一次上) ...
2. How to convert a string back to a list? You can use .split() for delimited strings or json.loads() for structured data. For example, using json.loads(): import json string = '["apple", "banana", "cherry"]' list_of_fruits = json.loads(string) print(list_of_fruits) # Output...
使用分隔格式(Delimited Formats) 绝对多数表型数据可使用pandas.read_table从硬盘中读取。有时需要手动操作。如: In [19]: !type examples\ex7.csv "a","b","c" "1","2","3" "1","2","3" 对任何带单字符分隔符的文件,可使用Python内置的CSV模块的reader对象,然后可以遍历reader会产生元组,元组的值...
