Calculating the Number of Missing Values
It should be noted that it isn't convenient to check each value of the dataset for the NaN. It is more convenient to see the number of missing values to conclude columns where we have NaNs.
As you remember, we have two functions to check for the missing values. To calculate the sum, just use the .sum() function. Thus, in general, we have 2 options for outputting the number of NaNs for each column:
data.isna().sum()
# Or
data.isnull().sum()
Okay, nothing complicated. Let's move on the task.
