Python用字典中的值替换键

我有一本字典：

['snow side'：'ice'，'tea time'：'coffee']

。我需要用文本文件中的值替换键

我的文本如下：

I seen area at snow side.I had tea time.
I am having good friends during my teatime.

转换为：

I seen area at ice.I had coffee.
I am having good friends during my coffee.

编码：

import re
dict={'snow side':'ice','tea time':'coffee'}
with open('text3.txt', 'r+') as f:
    content = f.read()
    for key,values in dict:
        matched = re.search(r'\.\(.*?\)', key)
        replaced = re.sub(r'\.\(.*?\)', '.(' + values + ')', values)
        f.seek(0)
        f.write(replaced)
        f.truncate()

请帮我修改代码！答案将不胜感激

我认为这里不需要正则表达式，简单的

>>> text = """I seen area at snow side.I had tea time.
... I am having good friends during my teatime."""
>>> 
>>> dict={'snow side':'ice','teatime':'coffee'}
>>> 
>>> for key in dict:
...     text = text.replace(key, dict[key])
... 
>>> print text
I seen area at ice.I had tea time.
I am having good friends during my coffee.

因此，您的原始示例更改为：

dict={'snow side':'ice','tea time':'coffee'}
with open('text3.txt', 'r+') as f:
    content = f.read()
for key in dict:
    content = content.replace(key, dict[key])
with open('text3.txt', 'w') as f:
    f.write(content)

---

这将在以下方面发挥作用：

d = {'snow side': 'ice', 'tea time': 'coffee'}
with open('text3.txt', 'r+') as f:
    content = f.read()
    for key in d:
        content.replace(key, d[key])
    f.seek(0)
    f.write(content)
    f.truncate()

此外，不要覆盖可能不需要的内置名称，如

dict

re

。您只需对输入d:@mu执行

無 是的，那是真的，谢谢你指出：）不过那只是个人的喜好。。除息的
