Question

例如：我有一个列表，它是：

[0,15,1,7,2,16]

我将需要将该列表输出到

[(1,7),(0,15),(2,16)]。

因此，从头开始每隔两个词进行拆分，并且子列表的第二个词也按升序排列。

除了导入数学之外，是否有一种无需使用任何python库函数即可执行此操作的方法？

Answer 1

具有列表理解和排序方法

l1 = [0,15,1,7,2,16]
def on_sec(v):
    return v[1]
print(sorted ([(l1[e], l1[e+1]) for e in range(0, len(l1), 2)], key=on_sec))

# OUTPUT: [(1, 7), (0, 15), (2, 16)]

Answer 2

尝试一下：

a = [0,15,1,7,2,16]
b = sorted([a[n:n+2] for n in range(0, len(a), 2)], key = lambda x: x[1])
print(b)    # OUTPUT : [[1, 7], [0, 15], [2, 16]]

Answer 3

Numpy对于此类拆分操作非常有用。我们可以使用reshape将其分成几对，然后根据第二个元素进行排序。

import numpy as np

l = [0,15,1,7,2,16]
split = np.reshape(l, (-1,2))
sorted(split, key = lambda x: x[1])

或者，我们也可以使用numpy进行排序：

split[split[:,1].argsort()]

Answer 4

a = [0,15,1,7,2,16] 
l = [] 
for i in range(0,len(a),2): 
    c = (a[i],a[i+1]) 
    l.append(c) 

l.sort() 
print(l)

Answer 5

您可以通过以下键使用函数l = [0, 15, 1, 7, 2, 16] sorted(zip(l[::2], l[1::2]), key=lambda x: x[1]) # [(1, 7), (0, 15), (2, 16)]：
