我想将一些mathjax代码保存到python中的.txt文件中。
x = "$\infty$"
with open("sampletext.txt","a+") as f:
f.write(x)
完全按预期工作
sampletext.txt
$\infty$
但是，当我尝试将转义序列保存在列表中
x = ["$\infty$"]
with open("sampletext.txt","a+") as f :
f.write(str(x))
sampletext.txt
['$\\infty$']
如何删除后者中的双反斜杠并将其另存为['$\infty$']？
也许这可以帮助您：
x = [r"$\infty$"]
with open("sampletext.txt","a+") as f:
f.write(''.join(x))
标记“ r”（原始）可用于保存带有特殊符号（例如“ \”）的字符串
或者如果您不知道列表中有多少项：
x = ["$\infty$"]
with open("sampletext.txt","a+") as f:
f.write(f"{''.join(x)}")
尝试一下：
x = [r"$\infty$"]
with open("sampletext.txt","a+") as f:
f.write(str(x))
r表示将字符串视为原始字符串，这意味着所有转义码都将被忽略。
