r/learnpython on Reddit: Removing trailing zeros from a list.
May 4, 2024 -
Lets say I have a list:
lyst = [1, 0, 4, 3, 0, 1, 0, 0, 0]
but I want to turn it into:
lyst = [1, 0, 4, 3, 0, 1]
How would I go about doing this? I'm trying to do synthetic division, so I need to cut out trailing zeros while leaving the zeros in between numbers protected.

February 23, 2019 - Alice yes bcz it's considered as 0 and 0 in python. ... False = 0 0 = 0 it will remove both print(False==0) lst=[False, None, 0, [], {}] print([x for x in lst if x != 0]) lst.pop(0) lst.remove(0) all have the same result, it might be beneficial to have all zeroes made into strings "0" lst=[False, None, "0", [], {}] print([x for x in lst if x != "0"])

Hi all,
let's say i have a list
result = [0, 0, 4, 5, 1, 3]
and i want to remove the leading zeroes from that list.
here is my code, is it pythonic?
for i in range(len(result)):
if result[i] != 0:
result = result[i:]
breakthis is part of the exercise, in the book 'Elements of programming interviews' i found code that is more complicated and i tottaly don't get it (but it works)
result = result[next((i for i, x in enumerate(result) if x != 0),
len(result)):] or [0]can someone explain me this? this is the best way to make it? I have read about next() function and i get that in the end this is result = result[2:].

Seems unnecessarily complex. If you don't care too much about time complexity I'd probably just do: while result[0] == 0: del result[0]

that's horrible code imo, yours is far more readable the only change you need to do is to handle an empty list: for i, v in enumerate(my_list): if v != 0: return my_list[i:] return [] if they wanted to do it in some way like that, it'd use itertools.dropwhile return list(itertools.dropwhile(lambda x: x == 0), my_list) theirs is running through a generator comp of all elements. if none pass the check, the default of len(result) is the return value of next theirs also returns [0] for an empty list, is it meant to do that?

Answer (1 of 3): This is clearly and obviously a home work problem; it is not a problem that any serious developer would face. You don’t define where there two zeros should be - at the start, the end, in the middle; do they have to be together or apart ? When you remove one of the zeros - ...

February 23, 2024 - The Boolean mask method in NumPy involves creating a boolean mask that identifies the non-zero elements of an array, and then using this mask to create a new array with only those elements. ... By using the Boolean mask method, we can create a new array that only contains the non-zero elements of the original array without using a loop. When working with multi-dimensional arrays in Python, removing zeros can be more complex than with traditional arrays.

def remove_values(the_list, val):
return [value for value in the_list if value != val]

Try using filter method:
list = [9,8,7,6,5,4,3,2,1,0,0,0,0,0,0]
filter(lambda x: x != 0,a) #iterates items, returning the ones that meet the condition in the lambda function
# [9, 8, 7, 6, 5, 4, 3, 2, 1]
