how to create a python series of an integer of length n in a loop

I am looping through a range

Loopnumber = []

for i in range(2):
   series1 = [10/01/2017, 30,10,2017, 21/11/2017]
   loopnumber = ?

Loopnumber.extend(loopnumber)

I wish to create a series of same length as series 1 which a datetime series, and which is of value i and every time the loop runs the values of i are appended to a vector called loopnumber

expected output is 

[0, 0, 0, 1, 1, 1, 2, 2, 2]

in this case expected output is

It's not clear why you need this, but you can extend a list within your for loop. Note also you need range(3) to iterate 3 times.

loop_list = []

for i in range(3):
    series1 = ['10/01/2017', '30,10,2017', '21/11/2017']
    loop_list.extend([i]*len(series1))

print(loop_list)

[0, 0, 0, 1, 1, 1, 2, 2, 2]
