I am coding a decision tree and a confusion matrix and I added loop counters to determine the run time of my code but it returns me 0.

L = 0
def creatematrixnull(target):
    global L
    uniquetarget =unique(target)
    # we specifie the type to ease the plot
    dataframe=pd.DataFrame(columns=uniquetarget,index=uniquetarget, dtype='int32')
    for i in range(len(uniquetarget)):
        dataframe.iloc[i]=[0]*len(uniquetarget)
        L=L+1
    return dataframe 
    creatematrix=creatematrixnull(targettest)
print(L)

This is an example of what I am talking about

What does the targettest data look like? It also seems you have formatted it incorrectly, the `creatematrix` function call should not be indented – Cypherjac Feb 21 '22 at 14:54
Also please where is the unique function defined or sourced from? – profnotime Feb 21 '22 at 15:06
@profnotime, `unique` is from **numpy** – Cypherjac Feb 21 '22 at 15:10
Okay I thought it was a custom definition. Thanks @Cypherjac – profnotime Feb 21 '22 at 15:13
Oh sorry about this @Cypherjac yes now it gives me 8 – Feb 21 '22 at 15:48
I still get 0 for the other ones – Feb 21 '22 at 15:49
