How to declare array of zeros in python (or an array …

October 10, 2018

Just for completeness: To declare a multidimensional list of zeros in python you have to use a list comprehension like this: buckets = [[0 for col in range(5)] for row in range(10)] to avoid reference sharing between the rows. This looks more clumsy than chester1000's code, but is essential if the values are supposed to be changed later.

List of zeros in python - Stack Overflow

October 10, 2018

You should use [0] * n to generate a list with n zeros. See why [] is faster than list() There is a gotcha though, both itertools.repeat and [0] * n will create lists whose elements refer to same id.#add code here to figure out the number of 0's you need, naming the variable n. listofzeros = [0] * n if you prefer to put it in the function, just drop in that code and add return listofzeros Which would look like this: def zerolistmaker(n): listofzeros = [0] * n return listofzeros sample output: >>> zerolistmaker(4) [0, 0, 0, 0] >>> zerolistmaker(5) [0, 0, 0, 0, 0] >>> zerolistmaker(15) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] >>>Meilleure réponse · 301$python 2.7.8 from timeit import timeit import numpy timeit("list(0 for i in xrange(0, 100000))", number=1000) > 8.173301935195923 timeit("[0 for i in xrange(0, 100000)]", number=1000) > 4.881675958633423 timeit("[0] * 100000", number=1000) > 0.6624710559844971 timeit('list(itertools.repeat(0, 100000))', 'import itertools', number=1000) > 1.0820629596710205 You should use [0] * n to generate a list with n zeros. See why [] is faster than list() There is a gotcha though, both itertools.repeat and [0] * n will create lists whose elements refer to same id . This is not a problem with immutable objects like integers or strings but if you try to create list of mutable objects like a list of lists ( [[]] * n ) then all the elements will refer to the same object. a = [[]] * 10 a[0].append(1) a > [[1], [1], [1], [1], [1], [1], [1], [1], [1], [1]] [0] * n will create the list immediately while repeat can be used to create the list lazily when it is first accessed. If you're dealing with really large amount of data and your problem doesn't need variable length of list or multiple data types within the list it is better to use numpy arrays. timeit('numpy.zeros(100000, numpy.int)', 'import numpy', number=1000) > 0.057849884033203125 numpy arrays will also consume less memory.40The easiest way to create a list where all values are the same is multiplying a one-element list by n . >>> [0] * 4 [0, 0, 0, 0] So for your loop: for i in range(10): print [0] * i23$ python3 >>> from itertools import repeat >>> list(repeat(0, 7)) [0, 0, 0, 0, 0, 0, 0]7zlists = [[0] * i for i in range(10)] zlists[0] is a list of 0 zeroes, zlists[1] is a list of 1 zero, zlists[2] is a list of 2 zeroes, etc.5zeros=[0]*4 you can replace 4 in the above example with whatever number you want.3If you want a function which will return an arbitrary number of zeros in a list, try this: def make_zeros(number): return [0] * number list = make_zeros(10) # list now contains: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]2Here is the xrange way: list(0 for i in xrange(0,5))1python - 2d array of zerosInitializing a list to a known number of elements in PythonAfficher plus de résultatstf.zeros | TensorFlowTraduire cette pagehttps://www.tensorflow.org/api_docs/python/tf/zerostf.zeros( shape ...
