Question

我尝试用Python翻译日期。如果字符串中包含“ January”，则将其替换为“ janvier”等。

我遍历json数据库。但是，如果同一字符串中有两个月（“ 9月”和“十月”），则仅翻译第一个。为什么？

datestring = datestring.replace(" - ", "-")

            # Trad french/english
            if "January" or "january" in datestring:
                x["auction_date"] = datestring.replace("January", "janvier")

            if "February" in datestring:
                x["auction_date"] = datestring.replace("February", "février")

            if "March" in datestring:
                x["auction_date"] = datestring.replace("March", "mars")

            if "April" in datestring:
                x["auction_date"] = datestring.replace("April", "avril")

...

Answer 1

您需要将替换分配回日期字符串，因为字符串在Python中是不可变的：

datestring = datestring.replace(" - ", "-")

# Trad french/english
if "January" or "january" in datestring:
    datestring = datestring.replace("January", "janvier")

if "February" in datestring:
    datestring = datestring.replace("February", "février")

if "March" in datestring:
    datestring = datestring.replace("March", "mars")

if "April" in datestring:
    datestring = datestring.replace("April", "avril")

# now make the assignment to your data frame
    x["auction_date"] = datestring
...

在此示例中，您不需要有条件。 Protected Async Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Await (addMeeting("MPP Test By Milind with API", 1, False, True, False, "", "")) End Sub本身就是支票。我建议以下。

datestring.replace("January", "janvier")

这可能不是最有效的，但可能更易于管理。

祝你好运。

P.S：想指出一个常见的麻烦

您有：

>>> datestring = "JanUarY"                                                                                              
>>> def english_to_french(month):
...     month = month.lower()
...     month = month.replace("january", "janvier")
...     month = month.replace("february", "février")
...     return month
...
>>> x = english_to_french(datestring)                                                                                   >>> print(x)
janvier

此检查中的# Trad french/english if "January" or "january" in datestring: x["auction_date"] = datestring.replace("January", "janvier")语句不会评估您的想法。 if之后的每个条件都将独立处理。这是一个例子。

and/or

相反

>>> if "January":
...     print(True)                                                                                                     ...
True
>>> mystr = "Bobby"                                                                                                     >>> if "January" or "january" in mystr:                                                                                 ...     print("Bobby will always be in January")                                                                        ...
Bobby will always be in January

还是最好的！

>>> if "January" in mystr or "january" in mystr:
...     print("Bobby will never be in January")
...
>>>

Python中仅替换了字符串的第一个单词
