QUESTION
I have three pyspark dataframes. I want to put the dataset reference in a dictionary, write a loop, perform some operations on these three dataframes, and then save them for further analysis. But I struggle with the last step. I have two questions:
In my code below, how do I access the results in
TRANSFORMS? When I type:print(TRANSFORMS[0])I only get this cryptic result:Is there a mistake in my code and the transormations are never made?How do I modify the function so it saves three datasets like
df_1_result, df_2_result, df_3_resultwhich I can then later use in further analysis?
ANSWER
Answered 2021-Nov-05 at 08:46There are a couple of issues here:
Issue 1: TRANSFORMS.append(multi_output) simply adds the function definition to the TRANSFORMS list. The function is never invoked. Also, we should define it outside the for-loop.
Issue 2: The statement under the second condition has a typo. The code below, should work as expected.
QUESTION
I want to make a hash of hash using the structure of an array. Each array element should be a subkey of the preceding array element. For example using the following arrays:
...ANSWER
Answered 2021-Jan-02 at 23:48This is sounding like an XY problem to me - I'm very suspicious that you've 3 separate, numbered arrays.
But I'll answer on the off chance you're seeing a more general case - the trick to doing this sort of thing is using a hash reference to traverse and reset.
QUESTION
I have a simple Dog class that I am trying to store information about in a dictionary. With multiple instances of the class, Im seeing that the values of the dictionary get overwritten with subsequent instances. Any idea why this is happening? Ive also included another variable that doesnt seem to change. I assume this is some attribute that has to do with Python Dictionaries. Any idea how to fix? Working on Python 3.6. Thanks in advance.
...ANSWER
Answered 2020-Nov-19 at 17:07You have created a class attribute info, which you update during each instance creation (you don't create a new one).
As this class attribute isn't used at all, and since you want each instance to have its own, separate info, just create it in __init__:
QUESTION
I am using Python/matplotlib to create a figure whereby it has three subplots, each returned from a different 'source' or class method.
For example, I have a script called 'plot_spectra.py' that contains the Spectra() class with method Plot().
So, calling Spectra('filename.ext').Plot() will return a tuple, as per the code below:
...ANSWER
Answered 2020-Mar-10 at 13:19One way to do this is:
QUESTION
import java.util.*;
public void readToolData(String fileName) throws FileNotFoundException
{
File dataFile = new File(fileName);
Scanner scanner = new Scanner(dataFile);
scanner.useDelimiter(",");
while( scanner.hasNext() )
{
String toolName = scanner.next();
String itemCode = scanner.next();
int timesBorrowed = scanner.nextInt();
boolean onLoan = scanner.nextBoolean();
int cost = scanner.nextInt();
int weight = scanner.nextInt();
storeTool(new Tool(toolName, itemCode, timesBorrowed, onLoan, cost, weight));
}
scanner.close();
}

Answered 2020-Feb-20 at 19:00The issue here is that your lines are not ending with a comma and there are newlines.
This is what your program is interpreting the first two lines of your input as:
QUESTION
Edit: This is not the right way to use interfaces in Go. The purpose of this question is for me to understand how empty interfaces work in Go.
If all types in Go implement interface{} (empty interface), why can't I access the name field in the Cat and Dog structs? How can I get access to the name field of each struct through the function sayHi()?
ANSWER
Answered 2020-Jan-29 at 23:12An interface{} is a method set, not a field set. A type implements an interface if it's methods include the methods of that interface. Since empty interface doesn't have any methods, all types implement it.
If you need to access a field, you have to get the original type:
