hup.base.literal module¶
Data type dependent string representation of objects.
-
as_datetime
(text: str, fmt: Optional[str] = None) → datetime.datetime¶ Convert text to datetime.
Parameters: - text – String representation of datetime
- fmt – Optional string parameter, that specifies the format, which is used to decode the text to datetime. The default format is the [ISO 8601]_ format, given by the string %Y-%m-%d %H:%M:%S.%f.
Returns: Value of the text as datetime.
-
as_dict
(text: str, delim: str = ', ') → dict¶ Convert text into dictionary.
Parameters: - text –
String representing a dictionary. Valid representations are: Python format: Allows keys and values of arbitrary types:
Example: “{‘a’: 2, 1: True}”- Delimiter separated expressions: Allow string keys and values:
- Example (Variant A): “<key> = <value><delim> …” Example (Variant B): “’<key>’: <value><delim> …”
- delim – A string, which is used as delimiter for the separatation of the text. This parameter is only used in the DSV format.
Returns: Value of the text as dictionary.
- text –
-
as_list
(text: str, delim: str = ', ') → list¶ Convert text into list.
Parameters: - text –
String representing a list. Valid representations are: Python format: Allows elements of arbitrary types:
Example: “[‘a’, ‘b’, 3]”- Delimiter separated values (DSV): Allows string elements:
- Example: “a, b, c”
- delim – A string, which is used as delimiter for the separatation of the text. This parameter is only used in the DSV format.
Returns: Value of the text as list.
- text –
-
as_path
(text: str, expand: bool = True) → pathlib.Path¶ Convert text into list.
Parameters: - text – String representing a path.
- expand – Boolen value, whoch determines, if variables in environmental path variables are expanded.
Returns: Value of the text as Path.
-
as_set
(text: str, delim: str = ', ') → set¶ Convert text into set.
Parameters: - text –
String representing a set. Valid representations are: Python format: Allows elements of arbitrary types:
Example: “{‘a’, ‘b’, 3}”- Delimiter separated values (DSV): Allows string elements:
- Example: “a, b, c”
- delim – A string, which is used as delimiter for the separatation of the text. This parameter is only used in the DSV format.
Returns: Value of the text as set.
- text –
-
as_tuple
(text: str, delim: str = ', ') → tuple¶ Convert text into tuple.
Parameters: - text –
String representing a tuple. Valid representations are: Python format: Allows elements of arbitrary types:
Example: “(‘a’, ‘b’, 3)”- Delimiter separated values (DSV): Allows string elements:
- Example: “a, b, c”
- delim – A string, which is used as delimiter for the separatation of the text. This parameter is only used in the DSV format.
Returns: Value of the text as tuple.
- text –
-
decode
(text: str, target: Optional[type] = None, undef: Optional[str] = 'None', **kwds) → Any¶ Decode text representation of object to object.
Parameters: - text – String representing the value of a given type in it’s respective syntax format. The standard format corresponds to the standard Python representation if available. Some types also accept further formats, which may use additional keywords.
- target – Target type, in which the text is to be converted.
- undef – Optional string, which respresents an undefined value. If undef is a string, then the any text, the matches the string is decoded as None, independent from the given target type.
- **kwds – Supplementary parameters, that specify the encoding format of the target type.
Returns: Value of the text in given target format or None.
-
encode
(obj: object, **kwds) → str¶ Encode object to literal text representation.
Parameters: obj – Simple object Returns: Literal text representation of given object.
-
estimate
(text: str) → Optional[type]¶ Estimate type of text by using
literal_eval()
.Parameters: text – String representation of python object. Returns: Type of text or None, if the type could not be determined.
-
from_str
(text: str, charset: Optional[str] = None, spacer: Optional[str] = None) → str¶ Filter text to given character set.
Parameters: - text –
- charset –
Name of used character set. Supportet options are:
printable: Printable characters UAX-31: ASCII identifier characters as defined in [UAX31]
Returns: String, which is filtered to the chiven character set.
