[PYTHON] Update package with pip standard features only

For the time being, it is for those who want to update the package managed only by the standard function of pip.

Preparation

The environment is Win7 64bit. If PyCharm is running, an access error will occur during the update, so please close it. Start a command prompt with administrator privileges and enter commands.

Display package list

pip list -o To get the list of packages. The package name is displayed at the beginning, followed by the current version and the latest version.

>pip list -o Pillow (2.8.1) - Latest: 3.2.0 [wheel] PySide (1.2.2) - Latest: 1.2.4 [wheel] setuptools (12.0.5) - Latest: 21.2.1 [wheel]
