text: Title: ZLMA newbie question
  Body: hello, I am new in Pandas and Pandas Ta,
  
  here is my code:
  ```python
  data=[1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10] #etc.. 
  df = DataFrame (data,columns=["Close"])
  zlma_list= ta.zlma(pd.Series(df['Close']))
  ```
  
  How can I change the original values of ZLMA
  ```python
  def zlma(close, length=None, mamode=None, offset=0, **kwargs):
  ```
  
  I tried this:
  
  ```python
  zlma_list= ta.zlma(close=pd.Series(df['Close'],length=21,mamode=sma))
  #changing the length is crucial for me. I did changes on original codes but it should be easier.
  ```
  but it doesnt work.
  
  
  also what is kwargs stand for? what is the aim of kwargs.
  
  thank you for understanding. I dont know is it good place to ask.
