【问题描述】：

我正在尝试将 pandas 数据帧转换为乳胶格式，但它在输出中返回了额外的斜杠。

数据

df = pd.DataFrame({\'model_name\': {0: \'ALBERT\', 1: \'a\', 2: \'b\', 3: \'c\', 4: \'d\', 5: \'e\'}, \'macro_precision_first\': {0: 91.89396817624747, 1: 92.17133890858452, 2: 92.6826295632407, 3: 92.80299948526579, 4: 93.34410168004217, 5: 92.0346638078341}, \'macro_recall_first\': {0: 92.2318448502444, 1: 92.3357692328841, 2: 93.0292033013862, 3: 93.12015088280738, 4: 93.66748596470968, 5: 92.36958589707638}, \'macro_f1_first\': {0: 91.95372391665576, 1: 92.23312713937592, 2: 92.71221623765801, 3: 92.88621653320901, 4: 93.43123707996612, 5: 92.1035266749227}})

当我尝试df.to_latex() 时，输出如下所示：

\'\\\\begin{tabular}{llrrr}\\n\\\\toprule\\n{} & model\\\\_name &  macro\\\\_precision\\\\_first &  macro\\\\_recall\\\\_first &  macro\\\\_f1\\\\_first \\\\\\\\\\n\\\\midrule\\n0 &     ALBERT &                  91.89 &               92.23 &           91.95 \\\\\\\\\\n1 &          a &                  92.17 &               92.34 &           92.23 \\\\\\\\\\n2 &          b &                  92.68 &               93.03 &           92.71 \\\\\\\\\\n3 &          c &                  92.80 &               93.12 &           92.89 \\\\\\\\\\n4 &          d &                  93.34 &               93.67 &           93.43 \\\\\\\\\\n5 &          e &                  92.03 &               92.37 &           92.10 \\\\\\\\\\n\\\\bottomrule\\n\\\\end{tabular}\\n\'

我期待的是这样的行：

ALBERT &                  91.89 &               92.23 &           91.95 \\\\ 
a      &                  92.17 &               92.34 &           92.23 \\\\
b      &                  92.68 &               93.03 &           92.71 \\\\
c      &                  92.80 &               93.12 &           92.89 \\\\
d      &                  93.34 &               93.67 &           93.43 \\\\
e      &                  92.03 &               92.37 &           92.10 \\\\

我怎样才能摆脱多余的斜线和\\\\\\n？

【解决方案1】：

斜杠是字符串中的转义字符。他们并不真正存在。尝试打印：

print(df.to_latex())

输出：

\begin{tabular}{llrrr}
\toprule
{} & model\_name &  macro\_precision\_first &  macro\_recall\_first &  macro\_f1\_first \\
\midrule
0 &     ALBERT &              91.893968 &           92.231845 &       91.953724 \\
1 &          a &              92.171339 &           92.335769 &       92.233127 \\
2 &          b &              92.682630 &           93.029203 &       92.712216 \\

5 &          e &              92.034664 &           92.369586 &       92.103527 \\
\bottomrule
\end{tabular}
