code and run commands ​

lamr provides a collection of Python code examples stored as plain text files. You can use lamr code and lamr run to see the code listing and run the files. lamr code also provides review questions, excercies and references for the code example.

Code collection ​

List the entire code collection:

console
>>> lamr code --list
cal.py  Print today's date and a calendar for current month.
logo.py Turn a string into ASCII art using a font style.
text.py Manipulate a string.
x.py    A Twitter clone (maybe).

Source file listing ​

Display the contents of cal.py file:

console
lamr code cal.py

This command will show the following output:

python
"""Print today's date and a calendar for current month."""

from calendar import TextCalendar
from datetime import date

t = date.today()
print("Today is", t)
print()  # prints empty line
TextCalendar().prmonth(t.year, t.month)

Run code ​

The calendar utility:

console
>>> lamr run cal.py
Today is 2024-02-04

   February 2024
Mo Tu We Th Fr Sa Su
          1  2  3  4

12 13 14 15 16 17 18
19 20 21 22 23 24 25
26 27 29

Make an ASCII art logo:

console
>>> lamr run logo.py
Sample font: slant
Sample text: Python 3
ASCII art:
    ____             __     __                           _____
   / __ \   __  __  / /_   / /_   ____    ____          |__  /
  / /_/ /  / / / / / __/  / __ \ / __ \  / __ \          /_ <
 / ____/  / /_/ / / /_   / / / // /_/ / / / / /        ___/ /
/_/       \__, /  \__/  /_/ /_/ \____/ /_/ /_/        /____/
         /____/

You can achieve similar result py piping the code command output to interpreter:

console
lamr code cal.py | python
lamr code logo.py | python

Build project using resources ​

For a list of follow-up questions, excercises and references run lamr code with one or more flags:

console
lamr code logo.py --questions
lamr code logo.py --excercises
lamr code logo.py --references
lamr code logo.py --all
