String-handling utilities to avoid locale-dependence.

Used primarily to generate type name aliases.

Function english_capitalize Apply English case rules to convert the first character of an ASCII string to upper case.
Function english_lower Apply English case rules to convert ASCII strings to all lower case.
Function english_upper Apply English case rules to convert ASCII strings to all upper case.

Variable _ascii_upper Undocumented
def english_capitalize(s): (source)

Apply English case rules to convert the first character of an ASCII string to upper case.

This is an internal utility function to replace calls to str.capitalize() such that we can avoid changing behavior with changing locales.

Examples

>>> from numpy.core.numerictypes import english_capitalize
>>> english_capitalize('int8')
'Int8'
>>> english_capitalize('Int8')
'Int8'
>>> english_capitalize('')
''
Parameters
s:str
Returns
strcapitalized
def english_lower(s): (source)

Apply English case rules to convert ASCII strings to all lower case.

This is an internal utility function to replace calls to str.lower() such that we can avoid changing behavior with changing locales. In particular, Turkish has distinct dotted and dotless variants of the Latin letter "I" in both lowercase and uppercase. Thus, "I".lower() != "i" in a "tr" locale.

Examples

>>> from numpy.core.numerictypes import english_lower
>>> english_lower('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_')
'abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz0123456789_'
>>> english_lower('')
''
Parameters
s:str
Returns
strlowered
def english_upper(s): (source)

Apply English case rules to convert ASCII strings to all upper case.

This is an internal utility function to replace calls to str.upper() such that we can avoid changing behavior with changing locales. In particular, Turkish has distinct dotted and dotless variants of the Latin letter "I" in both lowercase and uppercase. Thus, "i".upper() != "I" in a "tr" locale.

Examples

>>> from numpy.core.numerictypes import english_upper
>>> english_upper('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_')
'ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_'
>>> english_upper('')
''
Parameters
s:str
Returns
struppered
