what does 'rb' mean in csv files?
提问by evtoh
import csv
with open('test.csv','rb') as file:
rows = csv.reader(file,
delimiter = ',',
quotechar = '"')
data = [data for data in rows]
This was in Python: reading in a csv file and saving columns as variables. I couldn't comment, but I'm really confused. What does 'rb' mean?
这是在Python 中：读取 csv 文件并将列保存为变量。我无法发表评论，但我真的很困惑。'rb' 是什么意思？

From open()in the Built-in functions documentation:
从内置函数文档中的open()：
open(name[, mode[, buffering]])
The most commonly-used values of mode are
'r'for reading, (...) Thus, when opening a binary file, you should append'b'to the mode value to open the file in binary mode, which will improve portability.
打开（名称[，模式[，缓冲]]）
mode 最常用的值是
'r'读取，(...) 因此，在打开二进制文件时，您应该附加'b'mode 值以二进制模式打开文件，这将提高可移植性。
So this opens the file to read in a binary mode.
所以这会打开文件以二进制模式读取。
