  • windows下Python的安装,以及IDLE的使用

    
    一、Python的下载安装
    (1)python的windows安装包可以从https://www.python.org 网址中下载,可以下载3.4版本的或者2.7版本的。
    (2)下载后直接运行即可。然后将python的安装目录比如:"D:Program FilesPython36,添加到系统属性->环境变量Path中去。 (3)打开cmd,并且输入python即可以看到对应的python版本号信息等。 看python的windows版本安装简单吧,如果是linux类的版本则它们一般都自带有python,但一般版本偏低。 二、具有魔咒的"hello world" (1)新建一个txt文件,并且保存后缀为py (2)选中文件并且点击右键,这时在显示的列表中有一项"Edit with IDLE" 点击打开。 (3)IDLE是python中自带的一个小巧的python IDE。 (4)输入print('hello world') 或者print 'hello world' (5)点击F5 或者在IDLE中点击run即可以看到对应的输出信息。 好啦,这就是Python学习的第一步。

    关于IDLE,它只提供最基本的功能。但是它的启动以及执行时非常方便的。如果想使用其他的IDE可以使用PyCharm等工具。

    issue 1:

    >>> print 3*5
    File "<stdin>", line 1
    print 3*5
    ^

    need change to

    >>> print (3*5)
    15
    >>>

    pycharm 安装在windows 32 bit 报错 :

    fix: 

     was receiving error as "could not find main class com/intellij/idea/main" when trying to launch JetBrains Pycharm tool.

    Observation :- While checking this issue I tried below steps

     1. Uninstalled Pycharm tool and re-installed same using MSI installer.

    2. Checked Java( JDK) version which was 1.6 and also JRE  version as 1.6 on my computer.

    3. Downloaded latest version of Java( JDK & JRE) -1.8 and installed same to different location in C drive.

    4. Launched JetBrains Pycharm tool again and now it is working fine as expected.

    Happy to help !

    Hopefully this would work for people who are facing similar kind of issues. Thanks and let me know if you have any questions.
