Function range() in Python language does not give the expected result

Question

As a beginner in python, I was trying to test the function range() in the IDLE terminal. I wrote in the terminal the below posted code and I expected to see result like this:

range(10)==>[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

But unfortunately, i do not get the expected result

Python Code I Tried:

range(10)
print(range(10))

The Result From The shell:

>>>
print(range(10))

Answer 1

In python 3, range() returns a generator, that's why it shows you the object rather than the values:

>>> print(range(10))
range(0, 10)

If you were expecting a list, you will need to convert it to one before printing it:

>>> print(list(range(10)))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Generators only create one value at a time in order to save memory. You can read up on them here, which includes an example suited to your test case.

Cross version solution

>>> print(list(range(10)))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

>>> for i in range(10):
...     print(i)

Python2:

>>> print(range(10))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> print range(10)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> a = range(10)
>>> print(a)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Don't know your Python version, but mine works fine. Try specifying range(0,10) to be sure.
