typo is a python package to simulate typographical errors in English language.

Release 0.1.7

• Ability to preserve first and/or last characters in error methods.

Usage

import typo
import datetime

myStrErrer = typo.StrErrer('Hello World! Happy new year 2021.', seed=31)
print(myStrErrer.missing_char().result)
# Should print 'ello World! Happy new year 2021.'

myStrErrer = typo.StrErrer('Hello World! Happy new year 2021.', seed=31)
print(myStrErrer.missing_char(preservefirst=True).result)
# Should print 'Hllo World! Happy new year 2021.'

myStrErrer = typo.StrErrer('Hello World! Happy new year 2021.', seed=2)
print(myStrErrer.missing_char().char_swap().result)
# Should print 'Hlol World! Happy new year 2021.'

myIntErrer = typo.IntErrer(34343, seed=1)
print(myIntErrer.similar_digit().result)
# Should print 39343

myDateErrer = typo.DateErrer(datetime.datetime.strptime("8 Mar 95", "%d %b %y"))
print(myDateErrer.date_month_swap().result)
# Should print 1995-08-03 00:00:00

Currently, following types of typos can be simulated:
