Python コード スニペットを LaTeX で効率的に表示するにはどうすればよいですか?

Question

私は LaTeX の初心者で、このような単純な Python コードを LaTeX でプロフェッショナルな方法で表現する方法がわかりません。あなたの解決策と例があれば、学習と進歩に大いに役立ちます。

if transactions: Transaction.create_transactions() # if transactions = "true"
node.generate_emptyState() # empty state for all nodes
S.initial_events() # initiate initial events to start with

while not queue.isEmpty() and clock <= targetTime:
    next_e = queue.get_next_event()
    clock = next_e.time # move clock to the time of the event
    Event.execute_event(next_e)
    Queue.remove_event(next_e)

print results

Answer 1

これは私が好んで行う方法です。もちろん、色、フォント サイズ、境界線などを変更できます。

必要なのはピグメント使用するminted。

私は を好みますmintedが、 も使用できますpythonhighlight。これは、 -package の優れたフロントエンドですlistings。

\documentclass{article}
\usepackage{pythonhighlight}

\begin{document}
\begin{python}
if transactions: Transaction.create_transactions() # if transactions = "true"
node.generate_emptyState() # empty state for all nodes
S.initial_events() # initiate initial events to start with

while not queue.isEmpty() and clock <= targetTime:
      next_e = queue.get_next_event()
      clock = next_e.time # move clock to the time of the event
      Event.execute_event(next_e)
      Queue.remove_event(next_e)

print results
\end{python}
\end{document}

listingsあまりいじらずに良い結果を得るもう一つの方法は、solarzied-パッケージ:

\documentclass{article}
\usepackage{solarized-light}

\begin{document}
\begin{lstlisting}[language=python]
if transactions: Transaction.create_transactions() # if transactions = "true"
node.generate_emptyState() # empty state for all nodes
S.initial_events() # initiate initial events to start with

while not queue.isEmpty() and clock <= targetTime:
      next_e = queue.get_next_event()
      clock = next_e.time # move clock to the time of the event
      Event.execute_event(next_e)
      Queue.remove_event(next_e)

print results
\end{lstlisting}
\end{document}

{Piton}拡張機能 を使用できますpiton。これは LuaLaTeX の Lua ライブラリ LPEG を使用します (LuaLaTeX が必要です)。外部プログラムは必要ありません。

\documentclass{article}
\usepackage{xcolor}
\usepackage{piton}

\begin{document}

\begin{Piton}
from math import pi

def arctan(x,n=10):
   """Compute the mathematical value of arctan(x)

   n is the number of terms in the sum
   """
    if x < 0:
        return -arctan(-x) # recursive call
    elif x > 1: 
        return pi/2 - arctan(1/x) 
        #> (we have used that $\arctan(x)+\arctan(1/x)=\frac{\pi}{2}$ for $x>0$)
    else: 
        s = 0
        for k in range(n):
            s += (-1)**k/(2*k+1)*x**(2*k+1)
        return s 
\end{Piton}

\end{document}

と組み合わせて使用​​することも可能ですtcolorbox。

\documentclass{article}
\usepackage{xcolor}
\usepackage{piton}
\usepackage{tcolorbox}

\NewPitonEnvironment{Python}{}
  {\begin{tcolorbox}}
  {\end{tcolorbox}}

\begin{document}

\begin{Python}
from math import pi

def arctan(x,n=10):
   """Compute the mathematical value of arctan(x)

   n is the number of terms in the sum
   """
    if x < 0:
        return -arctan(-x) # recursive call
    elif x > 1: 
        return pi/2 - arctan(1/x) 
        #> (we have used that $\arctan(x)+\arctan(1/x)=\frac{\pi}{2}$ for $x>0$)
    else: 
        s = 0
        for k in range(n):
            s += (-1)**k/(2*k+1)*x**(2*k+1)
        return s 
\end{Python}

\end{document}
