python-examples

This is a collection of python examples I created for some key libraries in Python that I use all the time.

It is a way for me to remember and hopefully get others started.

Start your Python journey in Python 3. Onward and upward.

iptcinfo3 (download via pip3 install iptcinfo3)

1. iptcinfo3 example

imaplib (build-in python3x)

1. imaplib example

http.server Example

This example runs a web server to http://127.0.0.1:8000. Go to http://127.0.0.1:8000/web.html to verify it is working.

Run the example

python3 example-http-server.py

This will output that it is running on port 8000.

pdfquery Example

This example takes in the first argument the name of the pdf you want to get text from and prints the text found in the pdf to the screen.

Run the example

python3 pdfquery-example.py mypdf.pdf

This will output the text of the pdf to stdout if it contains any.

PDF Merge Example

This example reads in a list of pdfs, you can specify the prefix of the list of pdfs using the -p argument or default is read_. So for example, read_001.pdf, read_002.pdf would automatically get merged into a single pdf called merged.pdf. You can also set the output name via the -o argument.

Run the example

To get the help file:

python3 merge-pdfs-example.py -h

To run it on a list of pdfs with prefix test and output final.pdf:

python3 merge-pdfs-example.py -p test -o final.pdf

Pattern Twitter Search Example

The first example I created is pattern-example-twitter.py. Pattern is a great library that is installed via pip and can query Google, Twitter, etc. out of the box.

This twitter example connects to twitter and searches either a random string or terms you set via the terminal with the -s 'search terms'.

Terminal Example

python3 pattern-example-twitter.py -s 'Hello World'

Tor Connect Example

Tor (The Onion Router) has a particular socks port and connection setup that needs configured to connect in Python. This example shows you how. You must already have Tor installed.

Note: You need to install the Socksipy package for this to work, which has an actively maintained fork in PySocks. It is easy if you already have pip (and if you don't have pip you should). $ pip install PySocks

Then make sure your code (like the example) has import socks.

Run the tor connect example

Just simply run it from the terminal window:

python tor-example.py

This will return the DuckDuckGo .onion html as proof that it is working.

Google Search Example

The Google seach portion of the pattern library was very useful. This example shows you that you can compare the popularity of phrases or sets of terms together using percentages and the sort() command. It selects 10 random words to search on from the imported included dictionary list that is in the assets folder. This doesn't work anymore. Thanks for nothing Google.

Run the example

python3 pattern-example-google.py -c 'sexy'

Returns:

89.13% "sexy seemed"
2.17% "sexy impassive"
1.09% "sexy spiegels"
1.09% "sexy slumping"
1.09% "sexy quietuses"
1.09% "sexy noncooperation"
1.09% "sexy miriness"
1.09% "sexy incompliancy"
1.09% "sexy evaporators"
1.09% "sexy cudgeler"</code>

hug example

hug is a great easy-to-use api to help route things on your web app

Run the example

python3 hug_api_example.py

This will output hug and start a listener process on 127.0.0.1:8000

Then you can go to http://localhost:8000/happy_birthday?name=Hug&age=1 and see the output.

base64 Example

Converting data to base64 ensure a nice obsfuscation layer for data transport.

Run the base64 example

python3 base64_example.py

This will output a html string that is encoded into base64.

Html to Text Example

Beautiful Soup is a great library to parse and select html or iterate through the DOM. For this example to work you need to install Beautiful Soup via pip:

pip install bs4

Run the Example

python3 example-html2plaintext.py

Returns

[*-*]Before html with text:
------------------
<!DOCTYPE HTML>
<head>
<title>THIS IS AN EXAMPLE by @jamescampbell</title>
<meta author='jamescampbell'>
<style>a {font-family:arial;}</style>
</head><body>
<h1>Hello World</h1>
<p>I hope you enjoy this example.</p></body>
------------------



[*-*]After cleanMe() function:
-------------------
THIS IS AN EXAMPLE by @jamescampbell
Hello World
I hope you enjoy this example.
-------------------

FuzzyWuzzy Example

This example searches for 'cowboy' and returns Dallas Cowboys as the closest match from the list available.

Run the Example

python3 fuzzywuzzy-example.py

Returns

Dallas Cowboys, 90

Google Mask Example

This example used to do three things, 1. sets your search term, 2 . set your number of mask search terms, and 3. selects a random user agent for each search query. Google killed their API for this, so byebye.

Run the Example

doesn't work anymore because google killed their API

Server Example

This example starts an http server on localhost:10010 and returns data when you visit the page

Run the Example

python3 server-example.py

Scrapy Spider Example

This example gets the list of all internal links for any domain by following all internal homepage links and their links.

Run the Example

python3 spider.py -u jamescampbell.us

Bitcoin Wallet Example

This example queries the blockchain.info API for an example wallet address and returns the ip address and dates for the transactions as well as the final wallet balance.

Run the Example

python3 bitcoin-example-1.py

Exifread Example

This example gets the exif data from an image file

Run the Example

python3 exif-reader.py assets/cat.jpg
