I want to generate something like that in a function that receives 1 argument n using yield to generate:
1
1+2
1+2+3
…
…
1+2+3+⋯+n−1+n
That is my last try:
def suite(n):
total = 0
for i in n:
total+=i
yield total
and this is what I receive:
Traceback (most recent call last):
File "notebook", line 4, in suite
TypeError: 'int' object is not iterable
Your error is here:
for i in n:
n is an integer and not an iterable. Perhaps you wanted to use xrange() (Python 2 only) or range() (recommended on Python 3) here:
for i in range(n):
Note that this starts iteration at 0, not 1 (up to and including n - 1). You could either use range(1, n + 1), or simply add 1 to your sum:
def suite(n):
total = 0
for i in range(n):
total += i + 1
yield total
This hasn't really got anything to do with generators; wether or not you used yield, trying to loop over a plain int object doesn't work either way.
Because your function declaration doesn not correspond with for loop. You cannot iterate over integer, you should use some iterable instead. The simplest way is to use range:
The correct version is:
def suite(n):
total = 0
for i in range(n):
total += i
yield total
>>>suite(6)
Or, you can do another change to yield sum of some iterable:
def suite(iterable):
total = 0
for i in iterable:
total += i
yield total
>>>suite([1,2,3])
Use range to create an iterator to use in your for loop:
def suite(n):
total = 0
for i in range(1, n+1):
total+=i
yield total
