module 就是python代码文件,可以放执行语句,变量定义和函数等. 注意这写语句仅在首次被导入的地方执行一次. [1] 每个module都有它私有的符号表, 可以被它里面定义的任何函数访问. module可以导入其它modules. 也不必非得将import 语句放在module的开头. 被导入module的名字将被放到导入module的全局符号表中. import支...
大多数unix系统提供了一个叫做md5sum的命令,来读取一个文件的内容并计算出一个“校验和(checksum)”。不同的内容产生相同校验和的概率非常小。 可以使用一个管道来从python终运行md5sum,并得到计算结果。 filename = 'book.tex' cmd = 'md5sum' + filename fp = os.popen(cmd) res = fp.read() stat = f...

Check version of a Python module. Raises an error if the<module>.__version__: already present on PyPI or custom warehouse deployment; does not matchPEP 440; or does not match specified type: alpha/beta/rc/dev/release. All of this comes in handy during CI. ...
The code that is written in Python 2.x may not work in Python 3.x. The sys module that is available in all Python versions provides system-specific parameters and functions. sys.version_info allows you to determine the Python version installed on the system. It returns a tuple that ...
Here's another solution, using the ast module: python -c "import ast; ast.parse(open('programfile').read())" To do it cleanly from within a Python script: import ast, traceback filename = 'programfile' with open(filename) as f: source = f.read() valid = True try: ...

Check if a Python Module Is Installed I was once stucked in How to check Whether a Python module has been installed or not. After Googling, I found this trick. Python allows user to pass command from out of a python file.See here
Both options work equally well regardless of your system. The choice of which option to use really comes down to what format you want the output in. Using sys The sys module has a variable you can reference to get the current Python version. Below you can see an example of how the sys...
