`pip list -o` will tell you for which packages there are upgrades
available.
`pip install -U ...` will upgrade packages.

Be careful, though.
With `apt`, you usually have (`apt`) sources representing a consistent
package universe. Someone tests that package upgrades in this
universe do not break other packages (in this universe).
Because of this, upgrading poses low risk.

`PyPI` does not guarantes consistency. A new package version
may be incompatible to a previous one -- and with other
package you have installed.

I do not think that you would want to auto-upgrade all installed
packages.
