Trying to loop over index values - Intend to to get False value for every index number divided by 2
I can't figure out how get this code to no print the values if its falseBs4: Trying to loop in diferent arrays with diferent lenghts. Get IndexError: list index out of range
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;
I have a list such as:
bool_list = [False,False,True,True,True,True]
Now I plan to run a for loop to make sure that every index value divided by 2 gets converted to False. In case, the index value is not divided by 2 then it remains the same.
For example, I want a result in which the bool_list will display =
[False,False,False,True,False,True] as the 2nd and 4th index has been turned to False.
I have tried to write the following for loop using the enumerate function to get the index value but somehow it's giving me an error:
def mark_false(bool_list, p):
for idx,val in enumerate(bool_list):
if idx % p ==0:
bool_list[idx] ==False
else:
bool_list[idx] = bool_list[idx]
return (bool_list)
The function is going to be with p = 2

You can do this without a loop by replacing the slice of every other index with a list of False objects of the same length:
>>> bool_list = [False,False,True,True,True,True]
>>> bool_list[::2] = [False] * len(bool_list[::2])
>>> bool_list
[False, False, False, True, False, True]
