Hello Users,

I have my desired Tuple (see below) using the code mentioned. But I was wondering if there is any other clean way to obtain the same Output? (without using For/While Loops)

Desired Output:

((5, 5, 5, 5, 5, 5), (5, 5, 5, 5, 5, 5), (5, 5, 5, 5, 5, 5), (5, 5, 5, 5, 5, 5), (5, 5, 5, 5, 5, 5), (5, 5, 5, 5, 5, 5))

Used Code:

Ar_tuple=()
Mat_tuple=()
 
i=0
while i<6:
    Ar_tuple=(Ar_tuple + (5,)) 
    i=i+1                

j=0
while j<6:
    Mat_tuple=((Mat_tuple)+(Ar_tuple,)) 
    j=j+1
    
print(Mat_tuple)

Best Regards

((5,) * 5,) * 6

Note that this does not work well with lists. Lists are mutable, so instead of a list of six distinct sub-lists you will get a list of six references to the same list. It works with tuples because they are immuntable.
