如何打印指定列宽的列表

例如，我想打印mylist = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]然后打印新行

column = 5

或者我想打印print(mylist, column= 5) [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20]然后打印新行

column = 10

我知道我可以使用for循环来做到这一点，但我想知道是否有一个函数已经这样做了？

Answer 1

使用numpy数组而不是列表并重塑数组。

ValueError

当然，如果无法将array划分为column同等大小的列，则会抛出{{1}}。

Answer 2

不确定为什么，但我认为接近我认为你想要实现的东西可以通过将行数固定为-1来使用numpy数组重塑来完成

import numpy as np
array=np.array([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]) array
array([ 1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12, 13, 14, 15, 16, 17,
       18, 19, 20])
array.reshape(-1,5)

给出

array([[ 1,  2,  3,  4,  5],
       [ 6,  7,  8,  9, 10],
       [11, 12, 13, 14, 15],
       [16, 17, 18, 19, 20]])

array.reshape(-1,10)

给出

array([[ 1,  2,  3,  4,  5,  6,  7,  8,  9, 10],
       [11, 12, 13, 14, 15, 16, 17, 18, 19, 20]])

Answer 3

您也可以使用切片来完成此操作。

mylist = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]

def print_list(mylist, no_of_cols):
    start_index = 0
    for i in range(no_of_cols, len(mylist), no_of_cols):
        print mylist[start_index:i]
        start_index = i

    if len(mylist) > start_index:
        print mylist[start_index:len(mylist)]

print_list(mylist, 5)
