+If you want to find text located between specific characters or sequences of characters, you can use Python's `re` module and the `findall()` method.
+
+- Let's suppose you have the following string:
+
+    ```python
+    text = 'start Here is a line end'
+    ```
+
+- Imagine you want to find all the text between `'start'` and `'end'`. Here's the regex search you might use to do so:
+
+    ```python
+    import re
+    text = 'start Here is a line end'
+    matches = re.findall(r'start.*end', text)
+    ```
+
+- If you now check the `matches` variable in the interpreter, you will see that it is a list of the matches Python has found:
+
+    ```python
+    >>> matches
+    ['start Here is a line end']
+    ```
+
+- What happens if there is more than one match, like in the example below?
+
+    ```python
+    import re
+    text = 'start Here is a line end start and here is some more end'
+    matches = re.findall(r'start.*end', text)
+    ```
+
+    ```python
+    >>> match
+    ['start Here is a line end start and here is some more end']
+    ```
+
+- That wasn't what we wanted. This is because this regex is described as **greedy**. That means it searches the entire string before returning the match, and then returns all characters between the first `'start'` and the last `'end'`.
+
+- To make the **regex** non-greedy, you need to use a `.*?` rather than `.*`.
+
+    ```python
+    import re
+    text = 'start Here is a line end start and here is some more end'
+    matches = re.findall(r'start.*?end', text)
+    ```
+
+    ```python
+    >>> match
+    ['start Here is a line end', 'start and here is some more end']
+    ```
+
+- Now the list has two elements in it.
+
+- If you don't want Python to include the `start` and `end` words in the results, then you need to tell the **regex** to **look ahead** and **look behind**. There are two regex elements which will do that:
+
+- `?<=` means **look ahead**. Use it to search for text **after** the match.
+
+- `?=` means **look behind**. Use it to search for text **before** the match.
+
+- For these elements to work, you need to surround them and the pattern you're looking for in brackets:
+
+    ```python
+    match = re.findall(r'(?<=start).*?(?=end)', text)
+    ```
+
+    ```python
+    >>> match
+    [' Here is a line ', ' and here is some more ']
+    ```
+
+- What happens with strings spread across multiple lines, such as the one below?
+
+    ```python
+    import re
+    text = '''
+    start
+    Here is a line
+    end
+    start
+    and here is some more
+    end'''
+
+    match = re.findall(r'(?<=start).*?(?=end)', text)
+    ```
+
+    ```python
+    >>> match
+    []
+    ```
+
+- That's not what we wanted. The problem is that newlines (`\n`) stop the regex search. Adding a `flag` to the search can sort this out though:
+
+    ```python
+    import re
+
+    text = '''
+    start
+    Here is a line
+    end
+    start
+    and here is some more
+    end'''
+
+    match = re.findall(r'(?<=start).*?(?=end)', text, flags=re.DOTALL)
+    ```
+
+    ```python
+    >>> match
+    ['\nHere is a line\n', '\nand here is some more\n']
+    ```
