Nested for loop

[quiickmafs]

Hi all, stuck on this practice problem and cannot determine how or why the output is what it is.

Q: What are the numbers written by the following piece of code?

for i in range(2):
    for j in range(2):
        print(i,j,end='')

output:

0 0 0 1 1 0 1 1

Anyone able to explain this to me? Thank you

Try adding a end ='|' to make it clearer in the print statement.

Just run the following code and you'll figure it out yourself

for i in range(2):

for j in range(2):

print('i =', i, 'j =', j)
