Generating Random Data

Working With Missing Data | Dataquest

My query is regarding the below code given as an example. I have tried to read about it, but this seems like a complicated version. I would like to understand:

1. [1.0, np.nan] - i understand this parameter is an array. However, I do not understand the syntax.
2. p =[0.3,0.7] - again, i understand that this probability. Are we not biasing the dataframe with these probabilities ? Also, if you could help in understanding the syntax - is 0.3 for x and 0.7 for y -dimension variables?

However, I do not understand the syntax.

What specifically is confusing you about the syntax here?

@raturi22

Are we not biasing the dataframe with these probabilities ?

The dataframe being created with the randomly generated values is to only show the use of isnull() and sum(). There is not really a need to discuss any biases or why/how that particular p was selected.

Also, if you could help in understanding the syntax - is 0.3 for x and 0.7 for y -dimension variables?

I would suggest checking out the documentation for the function.
