如何将 Python 的字典数据填充到 Latex 的表中？

我在运行时将数据填入字典中。需要帮助将这些数据填充到 Latex 中的表中。

表格的代码片段：

f.write('\\end{itemize}\n')
f.write('\\begin{table}[ht]')
f.write('\\caption{Resolved issues}')
f.write('\\centering')
f.write('\\begin{tabular}{c c} ')
f.write('\\hline\\hline')
f.write(' Issue-Id & Summary \\\ [0.5ex] ')
f.write('\\hline ')
f.write(' 123 & Summary1 \\\ ')
f.write(' 456 & Summary2 \\\  [1ex] ')
f.write('\\hline ')            
f.write('\\end{tabular}')
f.write('\\label{table:nonlin}')
f.write('\\end{table}')

我已将 Issue-id 硬编码为 123 和 456。同样，Summary 为 Summary1 和 Summary2。

我的字典内容是这样的：

{'35871': ['Bad Loop Optimizations'], '35398': ['Bad long loop expansion], '36702': ['Crash reading a file']}

任何帮助深表感谢。

欢迎来到 TeX.SX！ 据我了解，你的问题似乎与 python 更相关，而不是与 TeX 更相关！

尝试以下代码：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

Shanthi = {'35871': ['Bad Loop Optimizations'], '35398': ['Bad long loop expansion'], '36702': ['Crash reading a file']}

with open("./Shanthi.tex", "w") as f:
    f.write('\\begin{table}[ht]\n\\caption{Resolved issues}\n\\centering\n')
    f.write('\\begin{tabular}{@{}c c@{}}\n\t\\toprule\n\t{\\bfseries Issue-Id} & {\\bfseries Summary} \\\\\n\t\\midrule\n\t')
    f.write("\\\\ \n\t".join(["{} & {}".format(_k, ", ".join(_v)) for _k, _v in sorted(Shanthi.items())]))
    f.write('\\\\\n\t\\bottomrule\n\\end{tabular}\n\\label{table:nonlin}\n\\end{table}')

它生成一个Shanthi.tex文件，其中包含：

\begin{table}[ht]
\caption{Resolved issues}
\centering
\begin{tabular}{@{}c c@{}}
    \toprule
    {\bfseries Issue-Id} & {\bfseries Summary} \\
    \midrule
    35398 & Bad long loop expansion\\ 
    35871 & Bad Loop Optimizations\\ 
    36702 & Crash reading a file\\
    \bottomrule
\end{tabular}
\label{table:nonlin}
\end{table}

因此，您可以在文件\input{Shanthi.tex}中使用main。请务必\usepackage{booktabs}在序言中添加，以便获得漂亮的表格（例如参见此处）。

提出的小改进projetmbc

（f 字符串仅适用于 python ≥ 3.6)

#!/usr/bin/env python

Shanthi = {
    '35871': ['Bad Loop Optimizations'], 
    '35398': ['Bad long loop expansion'], 
    '36702': ['Crash reading a file']
}

with open("./Shanthi.tex", "w") as f:
    backreturn = "\\\\\n" + " "*8

    content = backreturn.join([
        f"{_k} & {', '.join(_v)}" 
        for _k, _v in sorted(Shanthi.items())
    ])

    f.write(f"""
\\begin{{table}}[ht]
    \\caption{{Resolved issues}}
    \\centering
    \\begin{{tabular}}{{@{{}}c c@{{}}}}
        \\toprule
        {{\\bfseries Issue-Id}} & {{\\bfseries Summary}} \\\\
        \\midrule
        {content}\\\\
        \\bottomrule
    \\end{{tabular}}
    \\label{{table:nonlin}}
\\end{{table}}
    """.strip())

处理较大的单元格内容、长表格和 ID 重复项

只需使用-column (或)longtable代替table+即可。用元组列表替换字典。tabularpm

你的 Python 脚本：

#!/usr/bin/env python

Shanthi = [
    ('35871', 'Bad Loop Optimizations'),
    ('35398', 'Bad long loop expansion'),
    ('36702', 'Crash reading a file'),
    ('2692415', 'connect fatal error : System  Mixing wild card named port connection (.*) and position wrong while instanced with signals concatenated and tool generated "option.f"'),
    ('35871', 'Bad Loop Optimizations'),
    ('35398', 'Bad long loop expansion'),
    ('36702', 'Crash reading a file'),
    ('2692415', 'connect fatal error : System  Mixing wild card named port connection (.*) and position wrong while instanced with signals concatenated and tool generated "option.f"'),
    ('35871', 'Bad Loop Optimizations'),
    ('35398', 'Bad long loop expansion'),
    ('36702', 'Crash reading a file'),
    ('2692415', 'connect fatal error : System  Mixing wild card named port connection (.*) and position wrong while instanced with signals concatenated and tool generated "option.f"'),
    ('0', '\\lipsum[1]'),
    ('35871', 'Bad Loop Optimizations'),
    ('35398', 'Bad long loop expansion'),
    ('36702', 'Crash reading a file'),
    ('2692415', 'connect fatal error : System  Mixing wild card named port connection (.*) and position wrong while instanced with signals concatenated and tool generated "option.f"'),
]

with open("./Shanthi.tex", "w") as f:
    backreturn = "\\\\\n" + " "*4

    content = backreturn.join([
        f"{_tuple[0]} & {_tuple[1]}" 
        for _tuple in Shanthi
    ])

    f.write(f"""
\\begin{{longtable}}{{@{{}}cp{{.7\\textwidth}}@{{}}}}
    \\caption{{Resolved issues\\label{{table:nonlin}}}}\\\\
    \\toprule
    {{\\bfseries Issue-Id}} & {{\\bfseries Summary}} \\\\ \\midrule
    \\endfirsthead
    \\caption{{Resolved issues (continued)}}\\\\
    \\toprule
    \multicolumn{{2}}{{l}}{{\\scriptsize\\emph{{\\ldots{{}} continued}}}}\\\\
    {{\\bfseries Issue-Id}} & {{\\bfseries Summary}} \\\\ \\midrule
    \\endhead
    \\multicolumn{{2}}{{r}}{{\\scriptsize\\emph{{to be continued\ldots}}}}\\\\
    \\bottomrule
    \\endfoot
    \\bottomrule
    \\endlastfoot
    {content}\\\\
\\end{{longtable}}
    """.strip())

它会生成一个Shanthi.tex文件，您可以在其中调用它main.tex：

\documentclass[a4paper,12pt]{article}
\usepackage{booktabs}
\usepackage{longtable}
\usepackage{lipsum}

\begin{document}
    \input{Shanthi.tex}
\end{document}

答案2

顺便说一下

表格的代码片段：

f.write('\end{itemize}\n')

f.write（'\begin{table}[ht]'）...

当你 1) 将所需输出连接成一个长字符串，并且 2) 将其写出一次时，你的 Python 代码会变得更易读且更易于维护。请参阅https://www.w3schools.com/python/gloss_python_string_concatenation.asp有关详细信息，以及有关此策略的一些 Python 伪代码，保留潜在的反斜杠问题：

% assembling all required output
s = '\\end{itemize}\n'
s += '\\begin{table}[ht]'
s += '\\caption{Resolved issues}'
s += ...
% ...
f.write(s) % that's all, folks. "Just one f.write" (Like in 'The hunt for red october')

最好的祝愿

NBUR 的答案采用的是元组列表，而不是字典。问题要求将字典转换为 LaTex 表。以下是直接从字典转到 LaTex 表的改编代码：

def dict_to_latex_table(params:dict,key_header:str,value_header:str,caption:str):

    tuples=dict_to_latex_tuples(params)
    with open("latex/Tables/params_table.tex", "w") as f:
        backreturn = "\\\\\n" + " "*4

        content = backreturn.join([
            f"{_tuple[0]} & {_tuple[1]}" 
            for _tuple in tuples
        ])
    
        f.write(f"""
\\begin{{longtable}}{{@{{}}cp{{.7\\textwidth}}@{{}}}}
    \\caption{{{caption}\\label{{table:nonlin}}}}\\\\
    \\toprule
    {{\\bfseries {key_header}}} & {{\\bfseries {value_header}}} \\\\ \\midrule
    \\endfirsthead
    \\caption{{{caption} (continued)}}\\\\
    \\toprule
    \multicolumn{{2}}{{l}}{{\\scriptsize\\emph{{\\ldots{{}} continued}}}}\\\\
    {{\\bfseries {key_header}}} & {{\\bfseries {value_header}}} \\\\ \\midrule
    \\endhead
    \\multicolumn{{2}}{{r}}{{\\scriptsize\\emph{{to be continued\ldots}}}}\\\\
    \\bottomrule
    \\endfoot
    \\bottomrule
    \\endlastfoot
    {content}\\\\
\\end{{longtable}}
    """.strip())



def flatten_dict(some_dict:dict):
    flat_dict={}
    # Flatten dict
    for key, value in some_dict.items():
        if isinstance(value,dict):
            for newKey, newValue in value.items():
                flat_dict[newKey] = newValue
        else:
            flat_dict[key]=value
    print(f'flattend_params={flat_dict}')
    return flat_dict
    
def dict_to_latex_tuples(some_dict: dict):
    flat_dict=flatten_dict(some_dict)
    tuples=[]
    for key,value in flat_dict.items():
        if isinstance(key,str):
            key=key.replace("_"," ")
        if isinstance(value,str):
            value=value.replace("_"," ")
        tuples.append((key,value))
    return tuples

此外，列标题和标题也已参数化。并且用空格代替下划线。
