Do Python's str.__lt__ or sorted order characters based on their unicode index or by some locale-dependent collation rules?

Strings are sorted alphabetically, and numbers are sorted numerically. Note: You cannot sort a list that contains BOTH string values AND numeric values.
sort() method sorts the elements of a list in ascending or descending order using the default < comparisons operator between items. Use the key parameter to pass the function name to be used for comparison instead of the default < operator. Set the reverse parameter to True, to get the list in descending order.
sorted() , with no additional arguments or parameters, is ordering the values in numbers in an ascending order, meaning smallest to largest. The original numbers variable is unchanged because sorted() provides sorted output and does not change the original value in place.
To sort the DataFrame based on the values in a single column, you'll use . sort_values() . By default, this will return a new DataFrame sorted in ascending order. It does not modify the original DataFrame.
No, string ordering does not take locale into account. It is based entirely on the Unicode codepoint sort order.
The locale module does provide you with a locale.strxform() function that can be used for locale-specific sorting:
import locale
sorted(list_of_strings, key=locale.strxfrm)
This tool is quite limited; for any serious collation task you probably want to use the PyICU library:
import PyICU
collator = PyICU.Collator.createInstance(PyICU.Locale(locale_spec))
sorted(list_of_strings, key=collator.getSortKey)
