A python library for variable type checker/validator/converter at run time.
Project description
pytypeutil
Summary
A python library for variable type checker/validator/converter at run time.
Usage
Type Check
>>> from pytypeutil.type import Integer
>>> Integer(1).is_type()
True
>>> Integer(1.1).is_type()
False
Type Validation
>>> from pytypeutil.type import Integer
>>> Integer(1).validate()
>>> try:
... Integer(1.1).validate()
... except TypeError as e:
... print(e)
...
invalid value type: expected=INTEGER, actual=<type 'float'>
Type Conversion
convert
>>> from pytypeutil.type import Integer
>>> from pytypeutil import TypeConversionError
>>> Integer("1").convert()
1
>>> try:
... Integer(1.1).convert()
... except TypeConversionError as e:
... print(e)
...
failed to convert from float to INTEGER
try_convert
>>> from pytypeutil.type import Integer
>>> Integer("1").try_convert()
1
>>> print(Integer(1.1).try_convert())
None
force_convert
>>> from pytypeutil.type import Integer
>>> Integer("1").force_convert()
1
>>> Integer(1.1).force_convert()
1

Features
Supported types are as follows:
bool
datetime
dict
int
