Resolved: Missing value in a list
is there another faster way to know the missing value 20 beside using the (sorted) function,
cause if I have a longer list that might take a while to spot that number

Hi Doaa!
Thanks for reaching out.
Yes, you can use the set difference method to find the missing value quickly. Here's a short example:
all_values = set(range(1, 29)) # Assuming 1 to 28 are possible valuesmissing_values = all_values - set(df['Reason for Absence'].unique())print(missing_values)
The answer will be the set of missing values from your data. If the missing value is 20, the output will be:
{20}
Hope this helps.
Best,
