I know I can use the following syntax for loop in one line:
[print(x) for x in range(10)]
How can I use this syntax to combine two loops in one line?

**never do this**. You are talking about a *list comprehension*, which **is not** a single-line for-loop. Using list comprehension a for side effects is bad, don't do it. List comprehension are for mapping/filtering operations on iterables to *create a list* – juanpa.arrivillaga Nov 08 '20 at 21:54

Yes, it answers everything about your question. Read the accepted answer, it is quite extensive – juanpa.arrivillaga Nov 08 '20 at 21:59

You can use code something like below. It allows iterating by an array of arrays.
x = [[2,5,6],[3,5,1]]
result = [[value[i] for value in x] for i in range(3)]

[(i, j) for i in range(10) for j in range(10)] for instance or [[i for in range(j)] for j in range(10)] and you can combine those ideas in any way you want
