python 模块 版本

The ideal way of installing python libraries are using PIP (Python Package Manager). PIP provides an option to verify the version of the installed modules.

安装python库的理想方法是使用PIP(Python软件包管理器)。 PIP提供了一个选项来验证已安装模块的版本。

**The command to use to verify the version of the installed modules is**:

**用于验证已安装模块版本的命令为** ：

pip freeze

(venv) bash$:src XYZ$ pip freeze
    notebook==6.0.2
    numpy==1.17.2
    openpyxl==3.0.2
    pandas==0.25.3
    pandocfilters==1.4.2
    parso==0.5.2
    pexpect==4.7.0
    pickleshare==0.7.5
    prometheus-client==0.7.1
    prompt-toolkit==3.0.2
    ptyprocess==0.6.0
    Pygments==2.5.2
    pynb==0.1.36
    pyrsistent==0.15.6
    python-dateutil==2.8.1
    pytz==2019.3
    pyzmq==18.1.1
    qtconsole==4.6.0
    Send2Trash==1.5.0
    six==1.13.0
    soupsieve==1.9.5
    SQLAlchemy==1.3.12
    terminado==0.8.3
    testpath==0.4.4
    tornado==6.0.3
    traitlets==4.3.3
    wcwidth==0.1.8
    webencodings==0.5.1
    widgetsnbextension==3.5.1

The above list might be very exhaustive and in order to verify the version of a given module use the below command,

上面的列表可能非常详尽，为了验证给定模块的版本，请使用以下命令，

(venv) bash:src XYZ$ pip freeze | grep pandas
    pandas==0.25.3

Another option to verify the version of the module (without using PIP) is as follows,

验证模块版本(不使用PIP)的另一种方法如下：

# import the module 
    import pandas as pd 
    
    # print the version 
    print(pd.__version__)

**Output**

**输出量**

0.25.3

The above method is cumbersome in case we want to verify the version of multiple modules, as we have to write a print statement for every module. Hence the PIP way of verifying the version is preferred.

如果我们要验证多个模块的版本，上述方法比较麻烦，因为我们必须为每个模块编写一条打印语句。 因此，首选使用PIP验证版本。
