Help with two lines in a function

[amjass12]

check what reorderRows is in your first code example
just by inserting a print(reorderRows) before that line

df_cm = df_cm.reindex(index=[reorderRows])

Looking at your second code example

cm=cm.reindex(index=['1', '2', '3', '4', '5', '6'])

reorderRows must be the same as '1', '2', '3', '4', '5', '6' but if you assign it like this

reorderRows = '1', '2', '3', '4', '5', '6'

reorderRows is of type tuple ('1', '2', '3', '4', '5', '6')
and index=['1', '2', '3', '4', '5', '6'] is not the same as index=[('1', '2', '3', '4', '5', '6')]
which i assume you get printed out using print(reorderRows) as suggested because the error you get
KeyError: "[('1', '2', '3', '4', '5', '6')] not in index"
says exactly this

Thank you so much!! I am very sorry but i feel like i am doing something so wrong! I get your answer but i continue to get an error.. firstly, print(reorderRows in the first column, does not print the output after execution (snippet of code):

def kerasConfMat (classLabelPDindex,classLabelPDCols,reorderCols,reorderRows,actual, pred,hmcolor, xlab, ylab, fontsize, titlelab, xAxislab,yAxislab,titleFontSize, axisLabFontSize, colorbarlegend, annotatePlot):

    cm = confusion_matrix(actual.argmax(axis=1), pred.argmax(axis=1))
    cm = cm.astype('float') / cm.sum(axis=1)[:, np.newaxis]

    df_cm = pd.DataFrame(
     cm, index=classLabelPDindex, columns=classLabelPDCols)


    df_cm = df_cm[[reorderCols]]
[b]    print(reorderRows)
[/b]    df_cm = df_cm.reindex(index=reorderRows)

After execution I simply get the same error but not output of what reorderRows is:

Traceback (most recent call last):

    .format(mask=objarr[mask]))
KeyError: "[('p3', 'p15', 'p30', 'p60', 'p180', 'p365')] not in index"

Secondly, thank you for the clarification that does indeed make perfect sense! I feel like the solution was as follows:

Remove [] from the function so that the argument becomes:

df_cm = df_cm[[reorderCols]]
    print(reorderRows)
    df_cm = df_cm.reindex(index=reorderRows)

then define order=['1','2','3','4','5','6']

whose output =

Out[129]: ['1', '2', '3', '4', '5', '6']

This should make the format of of the function after inserting order in the argument:

df_cm = df_cm.reindex(index=['1', '2', '3', '4', '5', '6'])

Which should be in the correct format, however, i continue to get the same error:

KeyError: "[('p3', 'p15', 'p30', 'p60', 'p180', 'p365')] not in index"

I am really confused as to the specific issue here!
