Please help me to fix the Python error in b$)$ Return a list consisting of K values of the Aliquot sequence for n$..$ This sequence is defined by A$\_\{$k$+1\}=$ sum$($ func$($A$\_\{$k$\})),$ where A$\_1=$ n$.$ If func$()$ isn't provided, it defaults to factorize$().$

ddef aliquot$\_$sequence$($n$,$k$,$func$=$factorize$)$:

assert type$($k$)$ is int

assert k$>0$

Liste$=[]$

Liste.append$($n$)$

for n in range$($k$-1)$:

Test$=$sum$($func$($Liste$[$n$]))$

Liste.append$($Test$)$

if Test$==0$:

break

return Liste

pass

print$($ f'As a quick test, this code claims the Aliquot sequence for $4$ is $\{$aliquot$\_$sequence$(4,32,$factorize$)\}.\text{'})$

How do I fix the error: TypeError: 'int' object is not iterable when I run the code?
