Python bindings for wc(s)width
cwcwidth
provides Python bindings for wcwidth
and wcswidth
functions defined in POSIX.1-2001
and POSIX.1-2008 based on Cython. These functions compute the printable
length of a unicode character/string on a terminal. The module provides the same functions as
wcwidth and its behavior is compatible.
On systems not conforming to POSIX.1-2001 and POSIX.1-2008, Markus Kuhn's implementation is used to provide the functionality.
Cython >= 0.28
(optional, only for building). If Cython is not available, the C files are not
regenerated from their source.cwcwidth
can be installed via pip
:
pip install cwcwidth
or by running:
python3 setup.py install
>>> import cwcwidth
>>> cwcwidth.wcwidth("a")

>>> cwcwidth.wcswidth("コ")

>>> cwcwidth.wcswidth("コンニチハ, セカイ!")

>>> cwcwidth.wcswidth("コンニチハ, セカイ!", 5)
