似乎NumPy argsort在浮标上按字典顺序工作:
npSorted = np.array([[ "a", 12],
["B", 8 ],
["D", -0.96605562],
[ "e", -0.28283675],
["F", 0.22764316],
["T", 0.27752806],
["G", 0.36523876],
["H", 0.50737573],
[ "ME", 0.93213482]])
npSorted = npSorted[npSorted[:, 1].argsort()]
for sortedStock in npSorted:
print(sortedStock[0], ": ", sortedStock[1])
结果是:
e : -0.28283675
D : -0.96605562
F : 0.22764316
T : 0.27752806
G : 0.36523876
H : 0.50737573
ME : 0.93213482
a : 12
B : 8
那么我应该如何排序以获得0.5 <8 <12?
谢谢

就像@ Tomothy32所说的那样,不要使用异构数据。您可以执行以下操作来修复它。在排序前添加.astype(np.float)
1001 qc101 consented qc102;qc111
1001 qc102 notconsented qc102;qc111
1001 qc111 notconsented qc102;qc111
1221 qc244 notconsented qc244;qc201
1221 qc202 consented qc244;qc201
1221 qc201 notconsented qc244;qc201
