模块描述

A collection of string constants.

简要接口文档

__all__ = ["ascii_letters", "ascii_lowercase", "ascii_uppercase", "capwords",
           "digits", "hexdigits", "octdigits", "printable", "punctuation",
           "whitespace", "Formatter", "Template"]

模块全局变量

whitespace  -- a string containing all ASCII whitespace
ascii_lowercase  -- a string containing all ASCII lowercase letters
ascii_uppercase -- a string containing all ASCII uppercase letters
ascii_letters -- a string containing all ASCII letters
digits -- a string containing all ASCII decimal digits
hexdigits -- a string containing all ASCII hexadecimal digits
octdigits -- a string containing all ASCII octal digits
punctuation -- a string containing all ASCII punctuation characters
printable -- a string containing all ASCII characters considered printable

whitespace = ' \t\n\r\v\f'
ascii_lowercase = 'abcdefghijklmnopqrstuvwxyz'
ascii_uppercase = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
ascii_letters = ascii_lowercase + ascii_uppercase
digits = '0123456789'
hexdigits = digits + 'abcdef' + 'ABCDEF'
octdigits = '01234567'
punctuation = r"""!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~"""
printable = digits + ascii_letters + punctuation + whitespace

模块函数

def capwords(s, sep=None):  -->string
参数：
  s  --> 文本字符串
  sep  --> 分割依据，默认空格
返回值：
  string  --> 返回按分隔符分割后单词首字母大写后的字符串

模块类

class Template(metaclass=_TemplateMetaclass):
    delimiter = '$'  #  默认分隔符
    idpattern = r'(?a:[_a-z][_a-z0-9]*)' #  默认匹配字符串
    braceidpattern = None #  默认分割字符串
    flags = _re.IGNORECASE #  默认字符格式

    def __init__(self, template):
        self.template = template

    def substitute(*args, **kws):
        return self.pattern.sub(convert, self.template)

    def safe_substitute(*args, **kws):
        return self.pattern.sub(convert, self.template)

class Formatter:
    def format(*args, **kwargs):
        return self.vformat(format_string, args, kwargs)
