import pywt is a Python library that provides support for discrete wavelet transforms (DWT), wavelet packet transforms (WPT), and multilevel wavelet decomposition and reconstruction. It is used for signal and image processing tasks such as denoising, compression, feature extraction, and analysis.
You can install the pywt library using pip:
```
pip install PyWavelets
```
Once installed, you can import the library using the following line of code:
```
import pywt
```
From there, you can use the various functions and classes provided by the pywt library to perform wavelet-related operations. Let me know if you have any specific questions or need further assistance with pywt!
