Python函数定义在控制台中工作，但未导入到i​​python笔记本中

Question

我正在为一个项目开发一些帮助函数，我倾向于使用ipython-notebook来帮助dev。无论如何我碰到了一个奇怪的事情，我的函数定义在python控制台，ipython控制台上工作，或者如果我将函数定义粘贴到ipython-notebook单元格中。

但是，每当我尝试从ipython-notebook中加载模块并随后运行所述函数时，我都会收到以下错误。此外，如果我从控制台运行该函数并像往常一样导入或在ipython控制台中导入，一切正常。我可以导入该功能，它的工作原理。

要清楚，我实际上可以将该函数导入到ipython-notebook中，但实际运行该函数（导入后）会给出以下错误。在导入和运行相同功能的情况下，尽管代码完全相同，但其他方式（不在ipython-notebook中）不会产生相同的错误。

TypeError                                 Traceback (most recent call last)
<ipython-input-53-f4cd5ccd5841> in <module>()
----> 1 fr(100, 1000, c_unit='micro', i_unit='micro')

TypeError: resonant_frequency() got an unexpected keyword argument 'c_unit'

功能定义

def resonant_frequency(capacitance, inductance, c_unit='base', i_unit='base'):
    ''' *** electronics.electronics.py
        * Useful for LC circuit work
        * Both the capacitance and inductance should be in there
          base measurment units. I.e. 100 uHz (micro-hertz) should 
          be 0.0001 Hz etc.

        * Resonant frequency equation is fr = 1 / (2Pi * squrt(capacitance * inductance))
