How To See Packages Installed In Python

Python provides the Pip or Python Package Alphabetize which is used to add together useful actress modules to the Python. The pip is command is provided to search, install, update, and remove the modules provided by the Python Package Alphabetize. One of the well-nigh popular utilise cases for pip command is updating existing and already installed Python packages. In this tutorial, we will examine different cases for update and upgrade Python packages.

List Installed Python Packages with Pip

Before updating any package the all-time practice is listing installed packages. The pip command provides the listing parameter which will list installed packages. Also version information about the installed packages will be provided. pip is used for the Python2 and pip3 is used for the Python3.

          $ pip list  $ pip2 list  $ pip3 listing        

The following output will exist provided with the package names and version information.

          apturl 0.5.2 atomicwrites 1.i.5 attrs xix.iii.0 bcrypt 3.i.vii beautifulsoup4 4.viii.2 blinker ane.4 Brlapi 0.vii.0 certifi 2022.xi.28 chardet iii.0.4 Click 7.0 colorama 0.iv.three command-not-establish 0.iii cryptography 2.8 cupshelpers 1.0 cycler 0.10.0 dbus-python 1.2.sixteen decorator four.4.ii defer ane.0.6 distro 1.4.0 distro-info 0.23ubuntu1 duplicity 0.8.12.0 entrypoints 0.3 et-xmlfile ane.0.i fasteners 0.fourteen.1 future 0.18.ii html5lib 1.0.1 httplib2 0.14.0 idna two.viii importlib-metadata 1.five.0 jdcal 1.0 keyring eighteen.0.1 kiwisolver 1.0.ane language-selector 0.1 launchpadlib 1.ten.13 lazr.restfulclient 0.fourteen.2 lazr.uri ane.0.3 lockfile 0.12.ii louis 3.12.0 lxml 4.v.0 macaroonbakery i.3.1 Mako 1.one.0 MarkupSafe ane.1.0 matplotlib 3.1.2 monotonic 1.5 more-itertools 4.ii.0 netifaces 0.10.iv numexpr two.7.1 numpy one.19.1 oauthlib three.1.0 olefile 0.46 openpyxl 3.0.3 packaging xx.3 pandas 0.25.iii paramiko 2.6.0 pexpect 4.half-dozen.0 Pillow 7.0.0 pip 20.0.2 pluggy 0.13.0 protobuf 3.6.1 py ane.8.1 pycairo 1.sixteen.2 pycups 1.nine.73 PyGObject 3.36.0 PyJWT 1.7.1 pymacaroons 0.13.0 PyNaCl 1.three.0 pyparsing 2.4.vi pyRFC3339 1.one pytest 4.half-dozen.9 python-apt 2.0.0+ubuntu0.xx.4.ane python-dateutil ii.7.three python-debian 0.i.36ubuntu1 pytz 2022.3 pyxdg 0.26 PyYAML 5.three.i reportlab three.5.34 requests 2.22.0 requests-unixsocket 0.2.0 scipy 1.3.3 SecretStorage two.3.i setuptools 45.2.0 simplejson 3.xvi.0 half-dozen one.fourteen.0 soupsieve 1.ix.5 ssh-import-id 5.10 systemd-python 234 tables iii.6.1 ubuntu-advantage-tools 20.3 ubuntu-drivers-common 0.0.0 ufw 0.36 unattended-upgrades 0.1 urllib3 ane.25.8 usb-creator 0.three.7 wadllib 1.3.3 wcwidth 0.i.8 webencodings 0.5.one wheel 0.34.ii xkit 0.0.0 xlrd 1.1.0 xlwt 1.3.0 zipp 1.0.0        

Check If Specified Python Package Is Installated with Pip

As the list parameter lists installed pip packages with their version data we tin as well cheque for the specific packet by using an external command similar grep. We will provide the package name we desire to check and list. In the following example, we will check for different packages. If the bundle is non installed at that place will be no output. Nosotros can as well provide only some part of the packet proper noun and all matched packages will be listed below.

          $ pip3 listing | grep zipp zipp                   1.0.0                $  $ pip3 list | grep setuptools setuptools             45.2.0               $  $ pip3 list | grep django $  $ pip3 listing | grep Py PyGObject              3.36.0               PyJWT                  1.7.1                PyNaCl                 one.3.0                PyYAML                 5.3.ane                  

List Outdated Python Packages

Python is a dynamic programming linguistic communication and the modules provided by Pip updated regularly. Especially popular packages and projects become more frequent updates. Later installing a parcel it volition be outdated and should be updated. The pip control provides the listing --outdate parameter which volition list only outdated packages. This command will connect to the Pip repositories and collects installed packages information. It may take some time equally all installed packages will be queried from the Pip repository.

          $ pip3 listing --outdated  Packet            Version       Latest    Type  ------------------ ------------- --------- ----- atomicwrites       1.i.five         ane.4.0     wheel attrs              nineteen.three.0        20.2.0    bike bcrypt             3.1.7         3.2.0     bicycle beautifulsoup4     4.8.2         4.9.iii     wheel certifi            2022.xi.28    2022.6.20 cycle Click              vii.0           7.1.2     bike colorama           0.4.3         0.4.iv     wheel cryptography       2.8           3.two.1     wheel distro             ane.4.0         1.five.0     wheel distro-info        0.23ubuntu1   0.10      sdist duplicity          0.eight.12.0      0.8.16    sdist fasteners          0.fourteen.1        0.15      cycle html5lib           one.0.ane         1.1       wheel httplib2           0.xiv.0        0.18.1    wheel idna               ii.viii           2.x      bike importlib-metadata 1.5.0         2.0.0     cycle jdcal              1.0           1.4.i     cycle keyring            18.0.1        21.four.0    bicycle kiwisolver         1.0.1         ane.iii.0     wheel lazr.restfulclient 0.xiv.2        0.14.3    sdist lazr.uri           1.0.3         1.0.v     sdist lxml               4.5.0         iv.6.1     wheel Mako               i.one.0         1.1.3     wheel MarkupSafe         1.1.0         one.i.1     wheel matplotlib         3.1.two         iii.three.ii     wheel more-itertools     4.2.0         8.5.0     wheel netifaces          0.x.four        0.10.9    sdist numpy              1.19.ane        1.19.ii    wheel openpyxl           3.0.3         3.0.5     wheel packaging          20.3          twenty.four      wheel pandas             0.25.three        1.1.iii     wheel paramiko           2.half dozen.0         2.7.2     wheel pexpect            4.half-dozen.0         four.eight.0     bicycle Pillow             7.0.0         eight.0.1     wheel pip                xx.0.2        20.2.4    bike pluggy             0.13.0        0.thirteen.one    bike protobuf           3.6.1         three.13.0    wheel py                 1.viii.1         ane.9.0     wheel pycairo            i.16.2        1.twenty.0    sdist pycups             1.nine.73        two.0.1     sdist PyGObject          3.36.0        3.38.0    sdist PyNaCl             one.3.0         i.4.0     cycle pyparsing          ii.4.6         2.4.seven     wheel pytest             4.6.9         half-dozen.1.i     wheel python-dateutil    2.seven.3         2.8.1     wheel python-debian      0.1.36ubuntu1 0.1.38    wheel pytz               2022.iii        2022.1    cycle pyxdg              0.26          0.27      bike reportlab          3.v.34        three.five.54    wheel requests           two.22.0        2.24.0    wheel scipy              1.3.3         1.five.three     cycle SecretStorage      2.three.i         iii.one.2     wheel setuptools         45.2.0        fifty.3.ii    wheel simplejson         3.16.0        iii.17.two    wheel 6                i.xiv.0        1.xv.0    cycle soupsieve          ane.9.v         ii.0.1     wheel urllib3            1.25.8        1.25.eleven   wheel wadllib            1.3.3         ane.iii.iv     sdist wcwidth            0.1.8         0.2.5     bike cycle              0.34.two        0.35.1    bicycle xlrd               1.i.0         1.two.0     wheel zipp               1.0.0         iii.four.0     wheel                  

From the output we can see that the installed version of the package and most recent version provided past the Pip is listed for every package.

Update/Upgrade Python Parcel To The Latest Version with Pip

Now we have learned every step earlier updating or upgrade a Python package with pip. By the manner, both terms update and upgrade can be used for an update package but the pip command uses the install –user –upgrade parameter to update the packet. In the following example, we will update a specific package named lxml .

          $ pip3 install --user --upgrade lxml        

Update/Upgrade Python Packet To Specific Version with Pip

By default, the specified package will exist updated or upgraded to the latest version. But this can exist a problem if nosotros need a specific version of the Python package. This mostly occurs where some software depends on and supports a specific version of the Python package. We tin provide the version we want to update with the == sign and provide the version information.

          $ pip3 install --user --upgrade lxml==4.6.1        

Downgrade Python Package To The Specific version with Pip

The downgrade is the functioning of installing an older version of the specified package. We can downgrade the Python package to the specific version by using the == with the install command.

          $ pip3 install --user lxml==four.6.1
