Assistant: The `re` module in Python provides support for regular expressions, which are used for matching patterns in text. Here are some key functions and concepts:

1. **Basic Functions:**
   - `re.match(pattern, string)`: Checks for a match only at the beginning of the string.
   - `re.search(pattern, string)`: Searches for the first location where the pattern matches the string.
   - `re.findall(pattern, string)`: Returns a list of all non-overlapping matches of the pattern in the string.
   - `re.finditer(pattern, string)`: Returns an iterator yielding match objects for all non-overlapping matches.
   - `re.sub(pattern, repl, string)`: Replaces the matches with a specified replacement.

2. **Compiling Patterns:**
   - `re.compile(pattern)`: Compiles a regex pattern into a regex object for reuse, which can improve performance when using the same pattern multiple times.

3. **Match Objects:**
   - When a match is found using `match()`, `search()`, or `finditer()`, a match object is returned. This object contains methods and properties:
     - `.group()`: Returns the part of the string where there was a match.
     - `.start()`, `.end()`: Return the start and end positions of the match.
     - `.span()`: Returns a tuple with the start and end positions.

4. **Special Characters:**
   - `.`: Matches any character except a newline.
   - `^`: Matches the start of a string.
   - `$`: Matches the end of a string.
   - `*`: Matches 0 or more repetitions of the preceding pattern.
   - `+`: Matches 1 or more repetitions.
   - `?`: Matches 0 or 1 repetition.
   - `{m,n}`: Matches from m to n repetitions.

5. **Character Classes:**
   - `[abc]`: Matches any of a, b, or c.
   - `[^abc]`: Matches any character except a, b, or c.
   - `\d`: Matches any digit, equivalent to `[0-9]`.
   - `\w`: Matches any alphanumeric character or underscore.
   - `\s`: Matches any whitespace character.

6. **Flags:**
   - `re.IGNORECASE` or `re.I`: Ignore case.
   - `re.MULTILINE` or `re.M`: Multi-line matching.
   - `re.DOTALL` or `re.S`: The `.` matches any character, including newline.

Here's an example using `re.search`:

```python
import re

pattern = r'\bhello\b'
text = "hello world"

match = re.search(pattern, text)
if match:
    print("Found:", match.group())
else:
    print("Not found")
```
