I apologise for the terrible description and if this is a duplicated, i have no idea how to phrase this question. Let me explain what i am trying to do. I have a list consisting of 0s and 1s that is 3600 elements long (1 hour time series data). i used itertools.groupby()
to get a list of consecutive keys. I need (0,1) to be counted as (1,1), and be summed with the flanking tuples.
so
[(1,8),(0,9),(1,5),(0,1),(1,3),(0,3)]
becomes
[(1,8),(0,9),(1,5),(1,1),(1,3),(0,3)]
which should become
[(1,8),(0,9),(1,9),(0,3)]
right now, what i have is
def counter(file):
list1 = list(dict[file]) #make a list of the data currently working on
graph = dict.fromkeys(list(range(0,3601))) #make a graphing dict, x = key, y = value
for i in list(range(0,3601)):
graph[i] = 0 # set all the values/ y from none to 0
for i in list1:
graph[i] +=1 #populate the values in graphing dict
x,y = zip(*graph.items()) # unpack graphing dict into list, x = 0 to 3600 and y = time where it bite
z = [(x[0], len(list(x[1]))) for x in itertools.groupby(y)] #make a new list z where consecutive y is in format (value, count)
z[:] = [list(i) for i in z]
for i in z[:]:
if i == [0,1]:
i[0]=1
return(z)
dict
is a dictionary where the keys are filenames and the values are a list of numbers to be used in the function counter()
. and this gives me something like this but much longer
[[1,8],[0,9],[1,5], [1,1], [1,3],[0,3]]
edits: solved it with the help of a friend,
while (0,1) in z:
idx=z.index((0,1))
if idx == len(z)-1:
break
z[idx] = (1,1+z[idx-1][1] + z[idx+1][1])
del z[idx+1]
del z[idx-1]
Not sure what exactly is that you need. But this is my best attempt of understanding it.
def do_stuff(original_input):
new_original = []
new_original.append(original_input[0])
for el in original_input[1:]:
if el == (0, 1):
el = (1, 1)
if el[0] != new_original[-1][0]:
new_original.append(el)
else:
(a, b) = new_original[-1]
new_original[-1] = (a, b + el[1])
return new_original
# check
print (do_stuff([(1,8),(0,9),(1,5),(0,1),(1,3),(0,3)]))
