7.2.12. String Type¶

class typepy.String(value: Any, strict_level: int = 1, **kwargs)[source]¶

For each member methods, the result matrix for each strict_level is as follows. Column headers (except Method column) indicate input data to value argument of a method in the Method column. For each cell shows the output of the method.

`typepy.String`: `strict_level` = 0¶
Method	`"abc"`	`""`	`" "`	`None`	`1`
`is_type()`	`True`	`True`	`True`	`True`	`True`
`validate()`	NOP [1]	NOP [1]	NOP [1]	NOP [1]	NOP [1]
`convert()`	`"abc"`	`""`	`" "`	`"None"`	`"1"`

strict_level: Represents how much strict to detect the value type. Higher strict_level means that stricter type check.

convert()¶

Returns:	Converted value.
Raises:	typepy.TypeConversionError – If the value cannot convert.

force_convert()¶

Returns:	Converted value.
Raises:	typepy.TypeConversionError – If the value cannot convert.

is_type() → bool¶

Returns:
Return type:	bool

try_convert()¶

Returns:	Converted value. `None` if failed to convert.

validate(error_message: Optional[str, None] = None) → None¶

Raises:	TypeError – If the value is not matched the type that the class represented.
