...shell=False (default): In this case, the Popen class uses os.execvp() to execute the child program. args should normally be a sequence. A string will be treated as a sequence with the string as the only item (the program to execute). On UNIX, with shell=True: If args is a string, it specifies the command string to execute through the shell. If args is a sequence, the first item specifies the command string, and any additional items will be treated as additional shell arguments. On Windows: th...
...shell prompt runs a new instance of exec, compile() or execfile(). A future_statement typed at an interactive shell applies to the rest of the shell session's life, as if the future_statement had appeared at the top of a module. Resolved Problem: Simulated Interactive Shells Interactive shells "built by hand" (by tools such as IDLE and the Emacs Python-mode) should behave like native interactive shells (see above). However, the machinery used internally by native interactive shells has not b...

...Shell 'IPython' A 5-minute introduction to the enhanced interactive shell 'IPython'. Superior to the default Python shell, IPython provides power object introspection features, easy access to operating system commands and text editor integration. (actual video/screencast) A Demonstration of ReStructuredText A quick look at a style of marking up plaintext called "reStructuredText" with hotkeys from the Emacs text editor to view the result as HTML, PDF and slides.

...shell scripting. At that time, ILM was producing 15-30 shots per show, typically only a small part of each feature length film to which they were contributing. Looking ahead towards more CG-intensive films, ILM staff began to search for ways to control an increasingly complex and compute-intensive production process. It was around this time that Python version 1.4 came out, and Python was coming into its own as a powerful yet simple language that could be used to replace Unix shell scripting. Py...

...shells Developers of interactive shells are advised to add a filter that enables DeprecationWarning in the namespace where user code is entered and executed. If that namespace is __main__ (as it is for the default CPython REPL), then no changes are needed beyond those in this PEP. Interactive shell implementations which use a namespace other than __main__ will need to add their own filter. For example, IPython uses the following command ([8]) to set up a suitable filter: warnings.filterwarnings...

...shell command: subprocess.run(f"echo 'Hello {name}'", shell=True) If user-controlled data is included in the command string, the code is vulnerable to "command injection"; i.e., an attacker can run malicious commands. For example, a value of ' && rm -rf / # would result in the following destructive command being run: echo 'Hello ' && rm -rf / #' This vulnerability could be prevented by updating run to only accept LiteralString when used in shell=True mode. Here is one simplif...

...shell commands where needed. We use Perforce for source control, which keeps files read-only until they need to be edited. When running Cog, it may need to change files that the developer has not edited yet. It can execute a shell command to check out files that are read-only. Lastly, we used XML for our new property schema description, and Python's wide variety of XML processing libraries made parsing the XML a snap. An Example Here's a concrete but slightly contrived example. The properti...

...Shell Everything works the same inside Python's interactive REPL shell, except for module annotations in the interactive module (__main__) itself. Since that module is never "finished", there's no specific point where we can compile the __co_annotations__ function. For the sake of simplicity, in this case we forego delayed evaluation. Module-level annotations in the REPL shell will continue to work exactly as they do today, evaluating immediately and setting the result directly inside the __ann...
