python/flask TypeError：'float'对象不可调用

我正在部署使用python（Flask）编写的简单API，但出现奇怪错误“TypeError：'float'object is callable”。但是，对象是int型的，我确认了。我试着通过“for range in range（int（additional_params_count））”来强制执行int类型：“但它没有帮助。python/flask TypeError：'float'对象不可调用

下面是错误信息和源

您分配range在代码的浮动，不这样做，否则你无法访问range()内置然后：

if (lng != None) and (lat != None): 
    range = 0.1  ###########

De mo：

>>> range = 0.1 
>>> range() 
Traceback (most recent call last): 
    File "<ipython-input-39-7b0c968826c1>", line 1, in <module> 
    range() 
TypeError: 'float' object is not callable
