It doesn't matter whether you call them "accent" like most people do, or "diacritics" as linguists do. Either way, in some languages they are an integral part of the letter, like the horizonal stroke in English t or the vertical bar in English p and b, and in some languages they are modifiers, where there are rules that tell you how to write them without the modifier. In English, i is a letter with a dot diacritic, sometimes called the "tittle". But unlike Turkish, we don't have a dotless i, ı, and to add to the confusion when we capitalise i we get I with no dot instead of İ. Dropping the dot, or adding one when you shouldn't, can *literally* get you killed: http://gizmodo.com/382026/a-cellphones-missing-dot-kills-two-people-puts-three- more-in-jail http://www.theinquirer.net/inquirer/news/1017243/cellphone-localisation-glitch As far as I know, no natural language has a dotted capital J, but there is a dotless ȷ although I'm not sure what language it is from.

In general, there is no One Correct Way to translate accented characters into
ASCII. It depends on the language, and the word.
For instance, in English ö will usually be translated into just o with no
accent. We usually write coöperate and zoölogy as cooperate and zoology, or
sometimes with a hyphen co-operate, but never cooeperate or zooelogy. But if
the word is derived from German, or words that *look* like they might be
German, we do sometimes use oe: Roentgen rays (an old term for x-rays) after
Wilhelm Röntgen, for instance.
But in other languages the rules will be different. How, for example, should
one translate an Estonian word containing ö into Turkish, but using ASCII
letters only? I have no idea. But in both languages, and unlike German, ö is
*not* considered an o-with-an-accent, but a distinct letter of the alphabet.
https://en.wikipedia.org/wiki/Diaeresis_%28diacritic%29
As far as Python goes, if all you want to do is replace ö with oe and Ö into OE
(or perhaps you should use Œ and œ?) then you can use str.replace or
string.translate:
mystring.replace("Ö", "OE").replace("ö", "oe")

help() also uses a topics dict, from pydoc_data.topics, which gets
extracted when building the .rst docs. Check help('topics') and
help('keywords'). There's also help('symbols'), which lists the
punctuation symbols that help maps to various topics. For example,
help('**') gets mapped to help('POWER') and also prints a list of
related topics for the user, which includes "EXPRESSIONS" and
"OPERATORS" in this case.
Obviously modules in the standard library are documented in much more
detail in the python.org docs. pydoc_data would be gargantuan
otherwise. But I think there's actually enough info available in
help() that someone proficient in another language could use it to get
started programming in Python without any other documentation,
tutorials, or books.

MicroPython's array and struct modules use a common mp_binary_get_size function:
https://github.com/micropython/micropython/blob/v1.8.4/py/binary.c#L37
The array module uses native ("@") sizes, so the size of "i" and "I"
is sizeof(int).

What do you mean? It's not perfectly up-to-date with respect to

The help() function introspects the python source code and formats the docstrings found, so it will often be very much smaller. If you want a copy of the actual Python docs from the website, use a third-party downloader to mirror the docs.python.org site. (On Linux, you can use wget.) But before you do that, which is considered a bit rude, have you checked *both* the Download and Documentation pages on the website to see if there is a link to download the documentation? Or you can get the .rst files from Python's source repository, then use Sphinx to compile the .rst files to HTML. If you are using Linux, your package manager (such as yum, apt-get or similar) may have a package for the Python docs. Try `yum install python-docs` or similar. On the other hand, if you want help() to generate the documentation as a HTML page, I don't think the help() function itself will do it, but the pydoc module does.

Re: Is there something similar to `set -v` of bash in python
The manual says the following. "The trace function is invoked (with event set to 'call') whenever a new local scope is entered; it should return a reference to a local trace function to be used that scope, or None if the scope shouldn’t be traced." It means that one can not somehow settrace in one line and expect to get the trace function being called in the next line. So something like `set -v` in bash sounds not possible. Is it so?

SHRT_MAX <= INT_MAX <= LONG_MAX <= LLONG_MAX. short int and int ("h"
and "i") are at least 16-bit. long int ("l") is at least 32-bit. long
long int ("q") is at least 64-bit.
AFAIK, however, an int is 32-bit on all platforms supported by
CPython. However, I see that MicroPython [1] has been ported to 16-bit
PIC microcontrollers. An int should be 16-bit in that case.

Moreover, the Python interpreter does not have any notion of where the HTML documentation is stored, nor how to access it, nor how to present it. So no, a Python interactive prompt does not natively have a way to do what you're asking.

relied on. As far as I can tell, on all current Python implementations, “i” and
“I” have item sizes of 4, while “q” and “Q” have item sizes of 8.

How to convert 'ö' to 'oe' or 'o' (or other similar things) in a string?
Hi, I want to convert strings in which the characters with accents
should be converted to the ones without accents. Here is my current
code.
$ cat main.sh
#!/usr/bin/env bash
# vim: set noexpandtab tabstop=2:
set -v
./main.py Förstemann
./main.py Frédér8ic@
$ cat main.py

import sys
import unicodedata
print unicodedata.normalize('NFKD',
sys.argv[1].decode('utf-8')).encode('ascii', 'ignore')
The complication is that some characters have more than one way of
conversions. E.g., 'ö' can be converted to either 'oe' or 'o'. I want
to get all the possible conversions of a string. Does anybody know a
good way to do so? Thanks.

The trace module in the stdlib is little-known, but can do this. This will run your program and print each line before executing it: python -m trace -t yourprogram.py --Ned. -- https://mail.python.org/mailman/listinfo/python-list

Yes, on Windows (32 and 64bit), a long is always 32bit and an array with
datatype "L" has itemsize 4.

Rather easily. I've implemented it some time ago like this:
"""
import sys
def _traceit(frame, event, arg):
if (frame.f_globals['__name__'] == '__main__' and
event in ['call', 'line']):
logger.debug('+[{lineno}]: {code}'.format(
lineno = frame.f_lineno,
code = inspect.getframeinfo(frame).code_context
[0].rstrip()))
return _traceit
sys.settrace(_traceit)
"""
