Sometimes it is important to enforce a minimum Python version. See Nicholas Hairs' "Summary of Major Changes Between Python Versions" for a history of some reasons why that is...
- 'minpyver.py' - In some situations it is important to use a very specific Python version.
Yes, it might be better to just add:
if sys.version_info < (3, 10):
raise Exception("Use only with Python 3.10 or higher")I have another repo with with some Python logging content https://github.com/mccright/PythonLoggingExamples/
From Debuggex: https://www.debuggex.com/cheatsheet/regex/python
By Sundeep Agarwal https://learnbyexample.github.io/py_regular_expressions/ or the entire book in a single markdown file at https://github.com/learnbyexample/py_regular_expressions/blob/master/py_regex.md with supporting code at https://github.com/learnbyexample/py_regular_expressions
- This is a harness for evaluating the contents of files (in a directory and all child directories) using a collection of your own regex's. If you need specialized secrets-hunting utilities, see TruffleHog or Burp Suite Extension SecretFinder. I used ideas & code from both of them in this string search utility.
- Postman is great for most use cases, but I still sometimes need to poke at a simple API that accepts a POST with a secret in the POST data when my code is not working as expected. Here is a simple model for starting this kind of work in: https://github.com/mccright/PythonStuff/tree/main/simplePOST2API
(env) C:\temp\prob>python simpleAPIClient.py --help
usage: sampleAPIClient [-h] [-d] [-t] [-s] [-p] [-x PROXY_URL] -u API_URL
sampleAPIClient: an API Client POST skeleton for problem-solving
optional arguments:
-h, --help show this help message and exit
-d, --debug Use to send debug logging to console
-t, --timing Use to send timing to console
-s, --disable_cert_security
Use to disable SSL security checking. This can be a security risk concern. Use with caution.
-p, --proxy_needed Use to enable a proxy
-x PROXY_URL, --proxy_url PROXY_URL
When enabling a proxy, this is the full URL
-u API_URL, --api_url API_URL
Target api-endpoint - full URL
(env) C:\temp\prob>- This is not a point-and-shoot utility.
- At a minimum, you need to modify the code: Replace the "HEADER_PARAMS" and " POST_DATA" dicts with content relevant to your problem/target.
- Don't assume that I know what I am doing. This served its purpose on some weekend work. It has not seen many different use cases yet and may have serious limitations.
- This is not an attempt to deal with APIs that are protected by one or another OAuth implementation or other session-related interface. Its target are those simple POST-and-done APIs that ought to be simple to use, but sometimes are not.
Sometimes you need to know what types of files are in a github repo along with their layout in order to prepare for a risk-reasonable static analysis.
- getGHtree.py is a model for extracting a list of files in tree format from user repositories.
- getGHorgtree.py is a model for extracting a list of files in tree format from non-public organization repositories.
- getSomeIPInfo is just a reminder for me about navigating simple json. First using hard-coded references, and then iterating through every key/value pair. Both approaches have their place. There is another example used in getGHtree.py and getGHorgtree.py.
- useRandomUserAgent is just a reminder for me about rotating my user_agent strings.
- checkResponseCodes is a list of all the http Codes from the IANA Hypertext Transfer Protocol (HTTP) Status Code Registry in the form of a long 'case statement.' I wanted it around so that I could copy ot the subset that I needed at any given time. It is not meant to be used as is.
- http-response-codes is a CLI script that emits a list of all the http Codes from your current http module plus their short description & long description.
I usually pipe its output through grep for the code I am trying to understand. I found that when troubleshooting people's cloud-hosted lambdas & functions I run into more obscure response codes and need to check their meaning.
- createRandomStrings is some unfinished experimenting with different ways to create 'unique' strings, a common requirement...
encryptstr is a sketal set of AES-CBC string encryption/decryption functions.
get-pdf-text is an informal approach to using 'pypdf' to extract text from PDF files that often works well-enough for me. It is constructed from examples in the pypdf docs. pypdf can extract a range of PDF components.
- otherNotes.md is just a collection of short code fragments that act as reminders for me.

The Zen of Python by Tim Peters (1999). This is often described as the core philosophy of Python.

- Put a space before a comment:
# This is a comment - Don't make lines longer than ~80 characters
- Constants in all-caps:
MY_CONSTANT - Use underscores to separate words in variable names:
my_variable - Avoid meaningless variable names. Avoid numbers in variable names. Wrong:
thing1,thing2. Right:cat_list,fluffy_cat_list. - When ambiguous, put variable type in name:
my_listormy_set. This is particularly important for collections. Is it adictor alist? - Document code with triple quotes (multiline comments):
"""My documentation""" - Write functions when you find yourself repeating code
- When importing modules, don't import specific functions. Import the whole module, and use the module name and function together. Right:
import time; time.sleep(1). Wrong:from time import sleep; sleep(1). (Are there exceptions to this rule?) - When you find yourself checking if items are in a
list, use aset - Write a snippet of documentation at the top of your file to help you remember what the file does.
- Write inputs and outputs to functions in a comment in the function body.
- Debugging has its place, but don't hesitate to use print() statements.
(The original conventions in this list are from a readme by https://github.com/georgeberry. Thank you George Berry.)- And use Python f-strings to make your work easier.
- Use better-exceptions during local development, and use care to keep it out of your production deployments.
- Another approach would be to use pymg, a CLI tool that can interpret Python files by the Python interpreter and display the error message in a more readable way if an exception occurs https://github.com/mimseyedi/pymg
- What is the difference between using "_" and "__" in variable or function names? The responses get at some Python conventions: https://old.reddit.com/r/learnpython/comments/s5z0l8/can_someone_explain_and_in_python_clearly_for_me/
