Installation

pip install pyleetspeak

Examples of How To Use

The only required argument that the user has to provide is the text_in argument which represent the casual text to transform to leetspeak. Nonetheless, there are other optional arguments that control the behaviour of the transformation:`

• change_prb determines the probability of a transformation to take place (i.e, if it is equal 1 all the possible transformation will be applied).
• change_frq is affects how frequently a transformation will occur (i.e, if it is equal 1 all the letters of this transformation type will be changed)
• mode controls the level of leetspeak transformation. Currently only basic mode is available. We are working on more modes. Stay tuned.
• seed controls the reproducibility of the results. By default no seed is applied.
• verbose controls the verbosity of the proccess.

Basic Use

Let's see a simple working example:

from pyleetspeak import LeetSpeaker
text_in = "I speak leetspeak"
leeter = LeetSpeaker(text_in, change_prb=0.8,  change_frq=0.6, mode = "basic", seed = None, verbose=False)
leet_result = leeter.text2leet()
print(leet_result)
# "1 spe4k l33tsp34k"

For the sake of reproducibility you can set a random seed:

from pyleetspeak import LeetSpeaker
leeter = LeetSpeaker(text_in, change_prb=0.8,  change_frq=0.5, mode = "basic", seed = 42, verbose=False)
leet_result = leeter.text2leet()
print(leet_result)
# "1 sp34k l3etspeak"

Minor concerns about the package behaviour: accents are deleted using Unidecode. This is important for languages like Spanish, where the word "melocotón" is preprocessed as "melocoton" and finally transformed to leetspeak.

Get all changes

You can also obtain all the possible versions of a leetspeak text using the get_all_combs parameter like this:

from pyleetspeak import LeetSpeaker
text_in = "leetspeak"
leeter = LeetSpeaker(text_in, mode = "basic", get_all_combs = True)
leet_result = leeter.text2leet()
assert len(leet_result) == 32 # all possible combinations
print(leet_result)

Define your own changes

pyleetspeak is prepared to apply substitutions defined by the user. It is essential to highlight that these new user-defined changes have to follow two possible formats, dictionary or List of tuples. Here we show a toy example to add two new target characters from the original text to be replaced by two different characters and one, respectively:

• Dictionary type: {"target_chr_1": ["sub_chr_1", "sub_chr_1"], "target_chr_2": ["sub_chr_1"]}
• List[Tuple] type: [("target_chr_1", ["sub_chr_1", "sub_chr_1"]), (("target_chr_2", ["sub_chr_1"])]

You can add new user-defined substitutions:

from pyleetspeak import LeetSpeaker
text_in = "New changes Leetspeak"
obj = LeetSpeaker(
    text_in,
    change_prb=1,
    change_frq=0.8,
    mode="basic",
    seed=21,
    verbose=False,
    get_all_combs=False,
    user_changes = [("a", "#"), ("s", "$")], # user-defined changes
)
print(obj.text2leet())
# N3w ch@ng3$ L33t$pe4k

Moreover, you can use only the user-defined substitutions:

from pyleetspeak import LeetSpeaker
# Only user changes
text_in = "Only user changes: Leetspeak"
obj = LeetSpeaker(
    text_in,
    change_prb=1,
    change_frq=0.8,
    mode=None, # None pre-defined changes will be applied
    seed=21,
    verbose=False,
    get_all_combs=False,
    user_changes = [("a", "#"), ("s", "$")], # user-defined changes
)
print(obj.text2leet())
# Only u$er ch#nge$: Leet$pe#k
