如何编写一个以逗号作为小数点分隔符的csv? [英] How to write a csv with a comma as the decimal separator?

问题描述

我正在尝试在python中创建欧洲格式的csv.我已经将分隔符设置为分号

I am trying to create a european-formatted csv in python. I already set the separator to a semicolon

writer = csv.writer(response, delimiter=';', quoting=csv.QUOTE_ALL)

但是，它仍然使用点.作为小数点分隔符.使它使用逗号的正确方法是什么(对我的语言环境而言是正确的)? 我似乎找不到在文档中设置它的任何方法. (我正在使用，并且希望坚持使用内置的csv模块)

However, this still uses dot . as the decimal separator. What's the correct way to make it use a comma, as is correct for my locale? I can't seem to find any way to set it in the docs. (I am using, and would prefer to stick to, the built-in csv module)

推荐答案

有点笨拙，但这是我能想到的最好的方法:将浮点数转换为字符串并将.替换为,:

A little bit hacky way, but it's the best I can think of: convert floats to strings and replace . with ,:

def localize_floats(row):
    return [
        str(el).replace('.', ',') if isinstance(el, float) else el 
        for el in row
    ]

for row in rows:
    writer.writerow(localize_floats(row))

如果您希望更好地进行本地化处理，建议您使用 babel.numbers转换所有数字包.

If you want better localization handling, I suggest you convert all numbers using babel.numbers package.
