把反斜杠放进一根绳子里

latex file python-3.x

我有大量的长文本文件,我想转换成乳胶格式的表。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文档中的一个表,因此需要将其格式化为:

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\\

真正的文件会有几十行长,所以用手来做是不切实际的。

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 ,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
\
\

\\ \hline 进入 outfile

在 .txt 文件实际上有一个 \n 在句末! 为了在句末加些东西,我们应该注意这一点。

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'\\' ... 并跟随

如果要创建另一行,只需使用: outfile.write('\n') outfile.write(r'\hline') outfile.write('\n')

最终解决了这个问题:

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}')
