Writing A Grep Clone In 9 Lines Of Python - Python Regular Expressions Tutorial

In this video we show how you can use Python's regular expressions module to build a clone of the popular Unix tool 'grep' using only 9 lines of Python code. You can find the source code and a text version of this video here: https://blog.robertelder.org/grep-clone-in-9-lines-of-python/ Corrections: For the first example, I used the regex "[A-Z]N0" which will match any line that contains this pattern *anywhere* even part-way through a model number (so you'd only end up matching the last half of the model number). This could be fixed in Python by using a pattern like this instead: ", \s*[A-Z]N0". This way it will match the previous comma followed by any number of spaces before the model number, then followed by the model number pattern.
