Lorem Ipsum text

Lorem Ipsum text consists of semi-randomly generated but otherwise nonsense Latin-looking words.
This allows one to concentrate on the form and layout of the text without getting distracted by what the text says.

It is used in the financial printing industry and whenever text is needed for appearance purposes. Here is the Python code [#1]

import random
loremList1 = [
	"a", "ac", "accumsan", "ad", "adipiscing", "aenean", "aliquam",

Here is the output of the Python code.

1. [1] "dictumst ridiculus"
2. [2] "augue conubia consectetuer"
3. [3] "fermentum sed pulvinar dictum"
4. [1] "dictumst ridiculus blandit habitant cursus"
5. [2] "augue conubia consectetuer magnis eleifend ullamcorper"
6. [3] "fermentum sed pulvinar dictum massa senectus ornare"
7. [1] "dictumst ridiculus blandit habitant cursus per nostra orci"
8. [2] "augue conubia consectetuer magnis eleifend ullamcorper justo gravida sit"
9. [3] "fermentum sed pulvinar dictum massa senectus ornare suscipit sagittis blandit"

Note that the seed creates a pseudo-random number sequence that repeats when given the same seed.

Warning: The sequence repeats, but if any conditional statement execution causes a different sequence of calls to the random number generator where that value is used differently, then the program output is not repeatable.

In such cases, a random number generate is needed that is a class so that one can have different random number generators for each purpose.

Note how the use of the same random seed results in the same random sequence.

This is useful for deterministic (non-random) testing and can be turned off for (random) production use.

Here is a code module in Python [module rsLorem in rsLorem.py].

Here is the code using the rsLorem module.

Here is the Python code [#3]

from rsLorem import loremDo1
for pos1 in range(1,9+1):
	seed1 = ((pos1-1) % 3) + 1
	text1 = loremDo1(n1=pos1,seed1=seed1)
	print("{0:d}. [{1:d}] \"{2:s}\"".format(pos1,seed1,text1))

Here is the output of the Python code.

(module rsLorem imported)
1. [1] "dictumst ridiculus"
2. [2] "augue conubia consectetuer"
3. [3] "fermentum sed pulvinar dictum"
4. [1] "dictumst ridiculus blandit habitant cursus"
5. [2] "augue conubia consectetuer magnis eleifend ullamcorper"
6. [3] "fermentum sed pulvinar dictum massa senectus ornare"
7. [1] "dictumst ridiculus blandit habitant cursus per nostra orci"
8. [2] "augue conubia consectetuer magnis eleifend ullamcorper justo gravida sit"
9. [3] "fermentum sed pulvinar dictum massa senectus ornare suscipit sagittis blandit"

A common pattern is to count i from 1 to n but want a repeating sequence of 1 to d, starting at one (1), usually where d is less than n. In terms of i this is a three step process.

Subtract 1 (one) from i.
Take the remainder (mod) left over when divided by d.
Add 1 (one). If you want a repeating sequence from 0 to d-1, leave out this step.

Here is an example program to show the pattern. Here is the Python code [#4]

n1 = 16
d1 = 3
for i1 in range(1,n1+1):
	i2 = i1-1
	i3 = i2 % d1
	i4 = i3 + 1
	print("i={0:d} :: {1:d}-1={2:d} :: ({3:d}-1)%{4:d}={5:d} :: (({6:d}-1)%{7:d})+1={8:d}".format(i1,i1,i2,i1,d1,i3,i1,d1,i4))

Here is the output of the Python code.

i=1 :: 1-1=0 :: (1-1)%3=0 :: ((1-1)%3)+1=1
i=2 :: 2-1=1 :: (2-1)%3=1 :: ((2-1)%3)+1=2
i=3 :: 3-1=2 :: (3-1)%3=2 :: ((3-1)%3)+1=3
i=4 :: 4-1=3 :: (4-1)%3=0 :: ((4-1)%3)+1=1
i=5 :: 5-1=4 :: (5-1)%3=1 :: ((5-1)%3)+1=2
i=6 :: 6-1=5 :: (6-1)%3=2 :: ((6-1)%3)+1=3
i=7 :: 7-1=6 :: (7-1)%3=0 :: ((7-1)%3)+1=1
i=8 :: 8-1=7 :: (8-1)%3=1 :: ((8-1)%3)+1=2
i=9 :: 9-1=8 :: (9-1)%3=2 :: ((9-1)%3)+1=3
i=10 :: 10-1=9 :: (10-1)%3=0 :: ((10-1)%3)+1=1
i=11 :: 11-1=10 :: (11-1)%3=1 :: ((11-1)%3)+1=2
i=12 :: 12-1=11 :: (12-1)%3=2 :: ((12-1)%3)+1=3
i=13 :: 13-1=12 :: (13-1)%3=0 :: ((13-1)%3)+1=1
i=14 :: 14-1=13 :: (14-1)%3=1 :: ((14-1)%3)+1=2
i=15 :: 15-1=14 :: (15-1)%3=2 :: ((15-1)%3)+1=3
i=16 :: 16-1=15 :: (16-1)%3=0 :: ((16-1)%3)+1=1
