Pretty tables in Python

[3.14159265...]

I am very new to programming so please explain with examples.

I have a three dimensional array that I have filled, it started like this:

a = [[[0 for depth in range(0)] for row in range(20)] for col in range(20)]

Then I appended data to it as the calculations went on.

The output I want is a 2 dimensional array, indexed by column and range, where the entries of depth (ranging zero entries to 7 or 8) are listed.

Python does exactly what I want, but now I want to print it and look for the patterns I want by inspection. This needs a table that is not all over the place.
All help is appreciated.

For anyone really interested I am working on the 3x+1 problem.

don't know python

Java code

for (int depth=0; depth<20; depth++){

System.out.println("Matrix "+depth);

for(int row=0; row<20; row++){

for (int col=0; col<20; col++)

System.out.print(x[depth][row][col]+" ");

System.out.println(" "");

}//for row

System.out.println(" "");
System.out.println(" "");

}//for depth


The above assumes array has already been populated, that the array name is x, that the base indexes for dimensions start with 0 (range 0 to 19). The code will print 20 two-dimensional tables corresponding to depth=0, depth=1, depth=2, .., depth=19.

Thanks.

I ended up using a code that was already written by someone to get the exact output I needed .
