Lexical analysis

.. index:: lexical analysis, parser, token
A Python program is read by a *parser*. Input to the parser is a stream of
*tokens*, generated by the *lexical analyzer*. This chapter describes how the
lexical analyzer breaks a file into tokens.
Python uses the 7-bit ASCII character set for program text.
.. versionadded:: 2.3
An encoding declaration can be used to indicate that string literals and
comments use an encoding different from ASCII.
For compatibility with older versions, Python only warns if it finds 8-bit
characters; those warnings should be corrected by either declaring an explicit
encoding, or using escape sequences if those bytes are binary data, instead of
characters.
The run-time character set depends on the I/O devices connected to the program
but is generally a superset of ASCII.
**Future compatibility note:** It may be tempting to assume that the character
set for 8-bit characters is ISO Latin-1 (an ASCII superset that covers most
western languages that use the Latin alphabet), but it is possible that in the
future Unicode text editors will become common. These generally use the UTF-8
encoding, which is also an ASCII superset, but with very different use for the
characters with ordinals 128-255. While there is no consensus on this subject
yet, it is unwise to assume either Latin-1 or UTF-8, even though the current
implementation appears to favor Latin-1. This applies both to the source
character set and the run-time character set.
Python reads program text as Unicode code points; the encoding of a source file
can be given by an encoding declaration and defaults to UTF-8, see :pep:`3120`
for details. If the source file cannot be decoded, a :exc:`SyntaxError` is
raised.

Identifiers and keywords
========================
.. index::

Identifiers (also referred to as *names*) are described by the following lexical
definitions:
.. productionlist::
identifier: (`letter`|"_") (`letter` | `digit` | "_")*
letter: `lowercase` | `uppercase`
lowercase: "a"..."z"
uppercase: "A"..."Z"
digit: "0"..."9"
The syntax of identifiers in Python is based on the Unicode standard annex
UAX-31, with elaboration and changes as defined below.
Within the ASCII range (U+0001..U+007F), the valid characters for identifiers
are the same as in Python 2.5; Python 3.0 introduces additional
characters from outside the ASCII range (see :pep:`3131`). For other
characters, the classification uses the version of the Unicode Character
Database as included in the :mod:`unicodedata` module.
Identifiers are unlimited in length. Case is significant.
.. productionlist::
identifier: `id_start` `id_continue`*
id_start: <all characters in general categories Lu, Ll, Lt, Lm, Lo, Nl,
the underscore, and characters with the Other_ID_Start property>
id_continue: <all characters in `id_start`, plus characters in the categories
Mn, Mc, Nd, Pc and others with the Other_ID_Continue property>
The Unicode category codes mentioned above stand for:
* *Lu* - uppercase letters
* *Ll* - lowercase letters
* *Lt* - titlecase letters
* *Lm* - modifier letters
* *Lo* - other letters
* *Nl* - letter numbers
* *Mn* - nonspacing marks
* *Mc* - spacing combining marks
* *Nd* - decimal numbers
* *Pc* - connector punctuations
All identifiers are converted into the normal form NFC while parsing; comparison
of identifiers is based on NFC.

In plain English: String literals can be enclosed in matching single quotes
In plain English: Both types of literals can be enclosed in matching single quotes
(``'``) or double quotes (``"``). They can also be enclosed in matching groups
of three single or double quotes (these are generally referred to as
*triple-quoted strings*). The backslash (``\``) character is used to escape
characters that otherwise have a special meaning, such as newline, backslash
itself, or the quote character. String literals may optionally be prefixed with
a letter ``'r'`` or ``'R'``; such strings are called :dfn:`raw strings` and use
different rules for interpreting backslash escape sequences. A prefix of
``'u'`` or ``'U'`` makes the string a Unicode string. Unicode strings use the
Unicode character set as defined by the Unicode Consortium and ISO 10646. Some
additional escape sequences, described below, are available in Unicode strings.
The two prefix characters may be combined; in this case, ``'u'`` must appear

String literals may optionally be prefixed with a letter ``'r'`` or ``'R'``;
such strings are called :dfn:`raw strings` and use different rules for

Bytes literals are always prefixed with ``'b'`` or ``'B'``; they produce an
instance of the :class:`bytes` type instead of the :class:`str` type. They
may only contain ASCII characters; bytes with a numeric value of 128 or greater
must be expressed with escapes.
In triple-quoted strings, unescaped newlines and quotes are allowed (and are
retained), except that three unescaped quotes in a row terminate the string. (A
"quote" is the character used to open the string, i.e. either ``'`` or ``"``.)

.. index:: single: unrecognized escape sequence
.. index:: unrecognized escape sequence
Unlike Standard C, all unrecognized escape sequences are left in the string
unchanged, i.e., *the backslash is left in the string*. (This behavior is
useful when debugging: if an escape sequence is mistyped, the resulting output
is more easily recognized as broken.) It is also important to note that the
escape sequences marked as "(Unicode only)" in the table above fall into the
category of unrecognized escapes for non-Unicode string literals.
When an ``'r'`` or ``'R'`` prefix is present, a character following a backslash
is included in the string without change, and *all backslashes are left in the
string*. For example, the string literal ``r"\n"`` consists of two characters:
a backslash and a lowercase ``'n'``. String quotes can be escaped with a
backslash, but the backslash remains in the string; for example, ``r"\""`` is a
valid string literal consisting of two characters: a backslash and a double
quote; ``r"\"`` is not a valid string literal (even a raw string cannot end in
an odd number of backslashes). Specifically, *a raw string cannot end in a
single backslash* (since the backslash would escape the following quote
character). Note also that a single backslash followed by a newline is
interpreted as those two characters as part of the string, *not* as a line
continuation.
When an ``'r'`` or ``'R'`` prefix is used in conjunction with a ``'u'`` or
``'U'`` prefix, then the ``\uXXXX`` and ``\UXXXXXXXX`` escape sequences are
processed while *all other backslashes are left in the string*. For example,
the string literal ``ur"\u0062\n"`` consists of three Unicode characters: 'LATIN
SMALL LETTER B', 'REVERSE SOLIDUS', and 'LATIN SMALL LETTER N'. Backslashes can
be escaped with a preceding backslash; however, both remain in the string. As a
result, ``\uXXXX`` escape sequences are only recognized when there are an odd
number of backslashes.
escape sequences only recognized in string literals fall into the category of
