# Python Traceback Module

The `traceback` module provides a standard interface to extract, format and print stack traces of Python programs. It mimics the behavior of the Python interpreter when it prints a stack trace.

## Importing the Module

```python
import traceback
```

## Printing Exceptions

### `traceback.print_exc()`

This function prints exception information and stack trace entries from the traceback object to the file.

```python
import traceback
import sys

try:
    1 / 0
except Exception:
    traceback.print_exc(file=sys.stdout)
```

## Formatting Exceptions

### `traceback.format_exc()`

This is like `print_exc()` but returns a string instead of printing to a file.

```python
import traceback

try:
    1 / 0
except Exception:
    error_message = traceback.format_exc()
    print("Caught an exception:")
    print(error_message)
```

## Extracting the Stack

### `traceback.print_stack()`

This function prints a stack trace from its invocation point.

```python
import traceback

def f():
    g()

def g():
    traceback.print_stack()

f()
```
