pip freeze

This is a python built-in module that can help us know the dependent packages but it shows all dependencies as a flat list, finding out which are the top-level packages and which packages do they depend on requires some effort. Let us see an example of how it works:

Type given below command on your command prompt:

$pip freeze

Output:

altair==4.1.0
attrs==19.3.0
docutils==0.15.2
entrypoints==0.3
Jinja2==2.11.2
jmespath==0.10.0
jsonschema==3.2.0
MarkupSafe==1.1.1
numpy==1.18.4
opencv-python==4.2.0.34
pandas==1.0.4
pyrsistent==0.16.0
python-dateutil==2.8.1
pytz==2020.1
six==1.15.0
toolz==0.10.0
urllib3==1.25.9

Generally, many Python packages are dependent on other packages but how do we know that on which packages is a module dependent?
