How to see Python library in cmd?

To see the list of installed Python libraries in the Command Prompt (cmd), you can use the following methods:

Method 1: Using pip list

Open the Command Prompt and type the following command:

pip list

This will display a list of all the packages that are currently installed. You can also use the -n or --no-columns option to see a simple text-based output.

Example:

pip list -n
Package            Version

beautifulsoup4    4.9.3
certifi          2021.5.30
chardet         3.0.4
idna             2.10
...

Method 2: Using pip freeze

Open the Command Prompt and type the following command:

pip freeze

This will display a list of all the packages that are currently installed, along with their versions.

Example:

beautifulsoup4==4.9.3
certifi==2021.5.30
chardet==3.0.4
idna==2.10
...

Method 3: Using pip show

Open the Command Prompt and type the following command:

pip show --files

This will display a list of all the packages that are currently installed, along with their versions and file paths.

Example:

beautifulsoup4==4.9.3 /path/to/bautifulsoup4-4.9.3-py3-none-any.whl
certifi==2021.5.30 /path/to/certifi-2021.5.30.tar.gz
chardet==3.0.4 /path/to/chardet-3.0.4-py2.py3-none-any.whl
idna==2.10 /path/to/idna-2.10-cp38-cp38-win32.whl
...

Note: The file paths may not be displayed if you are running the command in a directory that does not contain any files for the packages.

Method 4: Using conda list (for Anaconda users)

If you are using Anaconda, you can use the conda list command to see the list of installed Python libraries.

conda list

This will display a list of all the packages that are currently installed, along with their versions.

Example:

# Name                     Version           Build  Channel
beautifulsoup4        4.9.3              py37    conda-forge
certifi                2021.5.30          py37    conda-forge
chardet                3.0.4              py37    conda-forge
idna                  2.10               py37    conda-forge
...
