i have defined a function called scores to calculate the F$1$ score, Precision, Recall and how to write a code to generate the Sensitivity and Specificity when my input is $5*5$ or $6*6$ matrix def scores$($cm$)$:

$p=\{\}$

$r=\{\}$

$f1=\{\}$

for $i$ in range$($ len$(cm)$ :

$p[i]=cm\frac{i,i}{{\displaystyle \underset{?}{\overset{?}{}}}}(cm[$:$,i])$

$r[i]=cm\frac{i,i}{{\displaystyle \underset{?}{\overset{?}{}}}}(cm[i,$:$])$

$f1[i]=2**(cm\frac{i,i}{{\displaystyle \underset{?}{\overset{?}{}}}}(cm[$:$,i]))**\frac{cm\frac{i,i}{{\displaystyle \underset{?}{\overset{?}{}}}}(cm[i,\text{:}])}{(cm\frac{i,i}{{\displaystyle \underset{?}{\overset{?}{}}}}(cm[\text{:},i]))+(cm\frac{i,i}{{\displaystyle \underset{?}{\overset{?}{}}}}(cm[i,\text{:}]))}$

return $p,r,f1$and put the codes in the function scores
