Missing Numbers challenge in Data Science course

Question

@sololearn admin
I got the same result as the target results, but the system doesn't recognize the result data as "SOLVED".
please help,
many thanks,

here is my script:

#====Missing Numbers======
import numpy as np
import pandas as pd
lst = [float(x) if x != 'nan' else np.NaN for x in input().split()]

lst = pd.array(lst)

k = -1
for i in lst:
k+=1
if np.isnan(lst[k]):
print(k,round(np.mean(lst),1))

else:
print(k,round(lst[k],1))

print("dtype:",lst.dtype)

Answer 1

Your output should be a pandas Series.
