array([
['192', '895'],
['14', '269'],
['1', '23'],
['1', '23'],
['50', '322'],
['19', '121'],
['17', '112'],
['12', '72'],
['2', '17'],
['5,250', '36,410'],
['2,546', '17,610'],
['882', '6,085'],
['571', '3,659'],
['500', '3,818'],
['458', '3,103'],
['151', '1,150'],
['45', '319'],
['44', '335'],
['30', '184']
])如何删除一些行并保留数组，如下所示：
Table3=array([
['192', '895'],
['14', '269'],
['1', '23'],
['50', '322'],
['17', '112'],
['12', '72'],
['2', '17'],
['5,250', '36,410'],
['882', '6,085'],
['571', '3,659'],
['500', '3,818'],
['458', '3,103'],
['45', '319'],
['44', '335'],
['30', '184']
])我删除了索引2,4,6。我不知道该怎么做。我试过几种方法，但还是不行。

看起来您实际上删除了索引2、5和10 (而不是2、4和6)。为此，您可以使用np.delete，向其传递要删除的索引的列表，并将其应用于axis=0
Table3 = np.delete(arr, [[2,5,10]], axis=0)
>>> Table3
array([['192', '895'],
['14', '269'],
['1', '23'],
['50', '322'],
['17', '112'],
['12', '72'],
['2', '17'],
['5,250', '36,410'],
['882', '6,085'],
['571', '3,659'],
['500', '3,818'],
['458', '3,103'],
['151', '1,150'],
['45', '319'],
['44', '335'],
['30', '184']],
