■ Generator comprehension

◆ When described normally
def g():
    for i in range(10):
        yield i

g = g()

print(type(g))
print(next(g))
print(next(g))
print(next(g))
print(next(g))
print(next(g))

result


<class 'generator'>
0
1
2
3
4
◆ When described in generator comprehension
g = (i for i in range(10))

print(type(g))

print(next(g))
print(next(g))
print(next(g))
print(next(g))
print(next(g))

result


<class 'generator'>
0
1
2
3
4

At first glance it looks like a tuple, but if you just use (), it becomes a generator.

g = tuple(i for i in range(10))

print(type(g))
print(g)

result


<class 'tuple'>
(0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

You can generate tuples by prefixing () with tuple.
