random interger array question

[rpang]

I being ask to create a random integer array with the info below:

● Create two random integer array of values 0 to 14 of size ten called x and y.
Concatenate x and y using the concatenate method. Assign it to Q5.

my code is :

np.random.seed(56)
x = np.random.randint(15, size= (10))
y = np.random.randint(15, size= (10))

Q5 = np.concatenate([x,y])

print(Q5)

my print:

Output:
[ 5  4  0  2 11 10 14  9 11  7  6  4  9 10  7  1  8 12  2 14]

correct print is:

Output:
[ 5  3  2  5  1  5  1 11 14 10  4  3  9  7  6  7  7 14  0  4]

wondering why the answer print from my code doesnt match the correct answer code. I have assign seed of 56.

Why would you expect, when working with random numbers, to get exactly the same answer as something else?

the answer suppose to be this :

Output:
[ 5  3  2  5  1  5  1 11 14 10  4  3  9  7  6  7  7 14  0  4]

which the question is asking me to spilt the random numbers

full question below:
● Create two random integer array of values 0 to 14 of size ten called x and y.
Concatenate x and y using the concatenate method. Assign it to Q5.
● Use the split method on Q5 to create each of the following:
Q6a: [5 3 2 5]
Q6b: [ 1 5 1 11 14 10 4]
Q6c: [3 9 7 6 7 7]
Q6d: [14 0 4]

but my code:

np.random.seed(56)
x = np.random.randint(15, size= (10))
y = np.random.randint(15, size= (10))

Q5 = np.concatenate([x,y])

print(Q5)

my print which is wrong:

Output:
[ 5  4  0  2 11 10 14  9 11  7  6  4  9 10  7  1  8 12  2 14]

generate a numbers which doesn't match the question print answer:

Output:
[ 5  3  2  5  1  5  1 11 14 10  4  3  9  7  6  7  7 14  0  4]

but if I run a code:

np.random.seed(56)
x = np.random.randint(15, size= (10,10))
y = np.random.randint(15, size= (10,10))

Q5 = np.concatenate([x,y])

print(Q5)

with the 10,10 i can see the correct numbers are listed on line 16.

Output:
[[ 5  4  0  2 11 10 14  9 11  7]
 [ 6  4  9 10  7  1  8 12  2 14]
 [11 11 14  0  5  6  1  9 10 12]
 [ 5  5  2 12  9  3  5  9  2 10]
 [ 1  0 13  4  6  2 12  0  8 13]
 [ 6 14  4 14  0 14  1 11  1 13]
 [12  3 14 14  9  6 13 10  2  1]
 [ 3  8  8  3  2  0  3  0  5  8]
 [ 0  8  6 12 10 13  0  9  4 11]
 [10 14 13  6  0 10  2  3  7  1]
 [11 11  6  5  0 11 12  6  8  2]
 [13  8  7 12  6  0  3  4  2  7]
 [ 2  4  5  0 14  7 10  1  1  8]
 [ 6  7  4 13  1  7  8 13  4 11]
 [ 3  6  2 10  5  0  8  0  5  3]
 [ 7  8  7  0 10 10  9 11  1  3]
 [ 5  3  2  5  1  5  1 11 14 10]
 [ 4  3  9  7  6  7  7 14  0  4]
 [14  8  9  0  1 11  1  3  6  7]
 [ 7  5  2  6  0 12  7 13 11  7]]

wondering what is wrong with my code?

I get your results. Are you sure about the seed value?
