'str' object has no attribute findall

The `findall` method is not available for `str` objects in Python. It is only available for `re` module's regular expression objects. If you want to find all occurrences of a pattern in a string, you can use the `re.findall()` function instead. Here's an example:

import re

text = "Hello, how are you? Are you doing well?"
pattern = r"\b\w{3}\b"  # Matches three-letter words

matches = re.findall(pattern, text)
print(matches)

This will output `['how', 'are', 'you', 'you']`, which are all the three-letter words found in the given text.

'str' object has no attribute 'findall'

这个错误通常是因为你尝试在字符串上调用 `findall` 方法，但是字符串类型并没有这个方法。`findall` 是正则表达式模块 `re` 中的方法，你需要先导入 `re` 模块，然后使用 `re.findall()` 方法来进行匹配。

例如，如果你想在一个字符串中查找所有的数字，可以这样写：

import re

s = "I have 3 apples and 5 oranges"
numbers = re.findall(r'\d+', s)
print(numbers)  # ['3', '5']

AttributeError: 'str' object has no attribute 'findall'

引用的赋值改为d[b]=[word。这样就能修复这个错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
