将反斜杠放入字符串中

Question

我有大量长文本文件，我想转换成LaTex格式的表。以下是其中一个文件的简短示例：

List of the best combinations (with |r-value| > 0.5)
Combination &   r value &   no.obs. &   Kendall's tau
============================================================
B - V   &   0.580019    &   11863   &   1.000000
B - R   &   0.574867    &   11863   &   1.000000
V - B   &   -0.580019   &   11863   &   1.000000
R - B   &   -0.574867   &   11863   &   1.000000

Highest r-value of 0.580019 occurred for B - V
Lowest r-value of -0.580019 occurred for V - B

我需要将其转换为LaTex文档中的表格，因此需要格式化为：

List of the best combinations (with |r-value| > 0.5)\\
\hline
Combination &   r value &   no.obs. &   Kendall's tau\\
============================================================\\
B - V   &   0.580019    &   11863   &   1.000000\\
\hline
B - R   &   0.574867    &   11863   &   1.000000\\
\hline
V - B   &   -0.580019   &   11863   &   1.000000\\
\hline
R - B   &   -0.574867   &   11863   &   1.000000\\
\hline

Highest r-value of 0.580019 occurred for B - V\\
Lowest r-value of -0.580019 occurred for V - B\\

真正的文件将长达数十行，因此手动完成是不切实际的。

我试过了

filename = file+'.txt'
with open(filename, 'r') as infile:
    new_filename = file+'_table.txt'
    with open(new_filename, 'w') as outfile:
        lines = infile.readlines()
        for line in lines:
            end_of_line = r'\\'
            outfile.write(line + end_of_line)
            outfile.write(r'\\hline')

以及来自here的建议，但我的输出是

\List of the best combinations (with |r-value| > 0.5)
\Combination    &   r value &   no.obs. &   Kendall's tau
\============================================================
\B - V  &   0.580019    &   11863   &   1.000000
\B - R  &   0.574867    &   11863   &   1.000000
\V - B  &   -0.580019   &   11863   &   1.000000
\R - B  &   -0.574867   &   11863   &   1.000000
\
\Highest r-value of 0.580019 occurred for B - V
\Lowest r-value of -0.580019 occurred for V - B
\
\

如何将\\和\hline插入outfile逐字？或者是否有任何其他工具可用于转换为LaTex格式？

Answer 1

在.txt文件中，实际上句子末尾有一个\n！为了在句末添加内容，我们应该小心这一点。

我想你可以在“for line in lines”中添加另一行来解决这个问题！

    line = line.replace("\n", " ")
    end_of_line = r'\\' 

......然后跟随

如果你想创建另一行，只需使用：

    outfile.write('\n') 
    outfile.write(r'\hline') 
    outfile.write('\n') 

我帮助这对你有用。

最终修复它：

with open(filename, 'r') as infile:
        new_filename = file+'_table.txt'
        with open(new_filename, 'w') as outfile:
            lines = infile.readlines()
            outfile.write(r'\begin{tabular}{|c|c|c|c|}')
            for line in lines[1:-3]:
                if line.startswith('='):
                    pass
                else:
                    line = line.replace('\n', ' '+r'\\'+'\n')
                    outfile.write(line)
                    outfile.write(r'\hline' + '\n')
            outfile.write(r'\end{tabular}')
