AttributeError: module 'babel' has no attribute 'numbers'

Question

目标：传递语言环境代码并检索货币符号。

我的方法是使用

babel

库。然而，我在版本

AttributeError

中遇到了一个

2.12.1

。

文档 | PDF页码：82

代码：

import babel

def get_currency_symbol(locale_code):
    try:
        return babel.numbers.get_currency_symbol(None, locale_code)
    except babel.core.UnknownLocaleError:
        print(f"Invalid locale code: {locale_code}")
        return '$'

print(get_currency_symbol('en_US'))
print(get_currency_symbol('fr_FR'))
print(get_currency_symbol('invalid_locale'))

Answer 1

导入

babel.numbers

使用子模块，而不仅仅是

babel

.
