Question

我有一个类似此示例的列表：

ImportError: dlopen: cannot load any more object with static TLS

In [2]: QXcbConnection: XCB error: 145 (Unknown), sequence: 171, resource id: 0, major code: 139 (Unknown), minor code: 20

我正在尝试将其导出到mylist = ['chr10 30930000 32110000 ARHGAP12,PFKP,ZEB1,ZNF438 4', 'chr15 76430000 77240000 ETFA,ISL2, 4']中。实际上每个text file和string would be one line。每个字符串中的每个every line would have 5 columns将是space separated part。因此，在one column中有一些column 4，它们将是comma separated characters。该文件将为in the same column。

对于该示例，预期的输出将如下所示：

tab separated

我正在chr10 30930000 32110000 ARHGAP12,PFKP,ZEB1,ZNF438 4 chr15 76430000 77240000 ETFA,ISL2 4中使用以下代码进行操作：

python

但是它不完全返回我想要的。你知道如何解决吗？

Answer 1

代替：


<style name="AppTheme" parent="Theme.MaterialComponents.Light">

按空格分隔后，按标签加入：

f.write("%s\n" % item+ '\t')

Answer 2

这应该非常简单，如下所示-

aa=['chr10 30930000 32110000 ARHGAP12,PFKP,ZEB1,ZNF438 4', 'chr15 76430000 77240000 ETFA,ISL2, 4']
with open("aa.txt","w") as wr:
    for item in aa:
        wr.write("\t".join(item.split(" ")) + "\n")

Answer 3

您的item中的每一个都是字符串，例如'chr10 30930000 32110000 ARHGAP12,PFKP,ZEB1,ZNF438 4'。我想您希望将每个列值之间的空格转换为制表符。为了达到这一目的，您应该添加另一个嵌套循环。像这样：

with open('outfile.txt', "w") as f:
    for line in mylist:
        for item in line.split(' '):
            f.write(item + '\t')
        f.write("\n")
