示例1: test_is_valid

# 或者: from trafaret import Float [as 别名]
def test_is_valid(self):
string_trafaret = t.Float()
assert string_trafaret.is_valid(1.5) == True
assert string_trafaret.is_valid('foo') == False 示例2: construct
# 需要导入模块: import trafaret [as 别名]
# 或者: from trafaret import Float [as 别名]
def construct(arg):
'''
Shortcut syntax to define trafarets.
- int, str, float and bool will return t.Int, t.String, t.Float and t.Bool
- one element list will return t.List
- tuple or list with several args will return t.Tuple
- dict will return t.Dict. If key has '?' at the and it will be optional and '?' will be removed
- any callable will be t.Call
- otherwise it will be returned as is
construct is recursive and will try construct all lists, tuples and dicts args
