Error: "TypeError: list indices must be integers, not str" in Python -

i trying import data file , using in function getting error:

door_position_pattern_actual = door_position[d]

typeerror: list indices must integers, not str

code references:

reactive_sampling_period_in_seconds = 10 * 60  door_position = list()  while 1:      line = f.readline()     vals = f.readline()     vals= vals.rstrip()     data1 = []     v in vals.split(","):         data1.append(v.lstrip())     if(entry[1]=="doorposition"):         door_position = list(data1)  def door_positin_fnc_actual(self, time_in_seconds):      time_period_in_10mins = 6     index = int(math.floor(time_in_seconds%(144*reactive_sampling_period_in_seconds)/(reactive_sampling_period_in_seconds)))     d in door_position :         door_position_pattern_actual = door_position[d]     return door_position_pattern_actual[index] 

output references:

print(door_position)  ['(1', '1', '1', '0', '1', '0', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '0', '1', '1', '1)'] 

i suspecting (1 creating prob not able fix it, kindly suggest me ...!!!

this wrong:

for d in door_position :     door_position_pattern_actual = door_position[d] 

d not index, it's value. doesn't make sense use in door_position[ ... ]

the error typeerror: list indices must integers, not str comes here.

perhaps looking this:

for d in range(len(door_position)) :     door_position_pattern_actual = door_position[d]
