Running the following code causes some strange behavior in python 2.7 and 3.5:
class Test():
def __init__(self):
self.arr = [1,2,3,4,5,6]
def worker(self):
for x in self.arr:
print (self.arr.pop(0))
b = Test()
b.worker()
Will cause the following output
>>> b.worker()
1
2
3
>>> b.worker()
4
5
>>> b.worker()
6
While the following code sample works as expected, printing the whole array in one go:
class Test():
def __init__(self):
self.arr = [1,2,3,4,5,6]
def worker(self):
for x in range(len(self.arr)):
print (self.arr.pop(0))
b = Test()
b.worker()
>>> b.worker()
1
2
3
4
5
6
What is going on here, why doesn't the first code sample print and reduce (pop) the whole array when the worker() is called?
