Question

我是python的新手，以下代码在分配i值时遇到问题

centriod_array如下所示

[115117112101 95 95 76 65 78 69 83 95 71 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 99 83 87 191 55 98 111 76

92 117 112 100 114 95 110 98 105 99 105 88 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 92 96 99 101 69 111 88 97

88 92 112 101 114 95 110 98 105 99 103 88 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 92 96 97 101 69 111 98 88 ]

def get_tx (centriods,cnt,flag):
for i in centriods:
    if i == " ":
       cnt = cnt+1
       if (cnt == 30 and cnt <= 37) :
         tx = i
         print (tx)



  k=0
    while k < 3:
        get_tx (centriod_array[k],0,0)
        k = k+1


it is printing as below:

9

....


>> i want it to be print like this 

99 83 87 191 55 98 111 76
92 96 99 101 69 111 88 97
92 96 97 101 69 111 98 88 



>> Basically i'm trying to print the values after "0".

Please help!!

以下实际上是数组中的确切元素，例如。抱歉造成混乱

我想提取片段并将它们分配给如下所示的变量：

其他具有非零到非零转换的数组（在这里我以粗体突出显示）

请帮助！

这可以按您期望的方式工作；利用rsplit中每个项目上的centroid_array来检索最后一个0之后的值：

centroid_array = ['115 117 112 101 95 95 76 65 78 69 83 95 71 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 99 83 87 191 55 98 111 76', 
                  '92 117 112 100 114 95 110 98 105 99 105 88 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 92 96 99 101 69 111 88 97', 
                  '88 92 112 101 114 95 110 98 105 99 103 88 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 92 96 97 101 69 111 98 88']

for x in centroid_array:
    print(x.rsplit(' 0 ')[-1])

# 99 83 87 191 55 98 111 76
# 92 96 99 101 69 111 88 97                                          
# 92 96 97 101 69 111 98 88

根据注释中的要求，检索从第50个空格到第200个空格的数字：

def get_tx(centriods):
    for i, x in enumerate(centriods.split()):
        if i >= 50 and i < 200:
            print(x, end=' ')

get_tx(s)

或者简单地：

print(' '.join(s.split()[50:200]))

其中s是您的输入。
