python3.X 二进制字符串的问题

Question

使用的版本为3.X我在使用numpy读取csv文件的时候出现了一种很奇怪的数据格式，导致我无法将日期字符串转换成datetime类型的数据 使用loadtxt读取一个文件后发现里面的数据虽然都是字符串，但是不知道为什么前面多...

怪我咯 · Answer

"b'10/31/2016'" 是str, b'10/31/2016' 是字符串 '10/31/2016'的binary格式，所以还是处理下数据吧，可以用loadtxt中的converters参数,re.sub("b|'", '', first_field) 把 b 和里面的'Replace the key and then convert the date
