pip install spelcheck

Automagically spellcheck your classes. Definitely do this.

After you've pip-installed it, just import spelcheck somewhere in your project (ideally before you define any classes). Some magic will then occur, and your typos will be fixed. Observe:

>>> import random
>>> import spelcheck
>>> class Employee:
...     def __init__(self, name, title):
...         self.name = name
...         self.title = tilte  # oops, we misspelled "title"
...         eslf.salary = radnom.randint(1, 10000)  # damn, misspelled "random"
...
...     def __str__(self):
...         return f"<Employee: {self.name}, {self.title} (€{self.salary})>"

>>> e = Employee("Steve", "Accountant")
>>> print(e)
<Employee: Steve, Accountant (€4325)>

If the autocorrection is too aggressive for you (or not aggressive enough) you can set the minimum fuzzywuzzy score (default: 75) before defining any classes:

import spelcheck
spelcheck.SPELCHECK_MINSCORE = 95  # be more precise
spelcheck.SPELCHECK_MINSCORE = 50  # be more aggressive

• Closures don't work. That is: we can't automatically correct a typo that should be a nonlocal name. I don't know if this is possible at all without changing our technique completely (maybe by parsing the source and looking at what function the inner function is defined in and what names exist there).
• Support Python 3.8. At the moment this doesn't seem to work in 3.8, I assume this is because of positional-only arguments which may have changed how a code object looks like. This seems doable.
