[英]replace characters in Pandas DataFrame
I want to export following chart to LaTex and replace my '+/-' with '±', just for the looks.我想将以下图表导出到 LaTex 并将我的 '+/-' 替换为 '±',只是为了外观。 Though, no matter what character I try (could also be an 'a' or anything else) it either doesn't change a bit or the column is empty.但是,无论我尝试什么字符(也可以是“a”或其他任何字符),它要么不会改变一点,要么该列是空的。 I found the code on several forums and I don't know what I'm doing wrong.我在几个论坛上找到了代码,我不知道我做错了什么。
df = pd.DataFrame({'A': ["3.90+/-0.04", "3.550+/-0.035", "3.250+/-0.033"],'B': [0.04175, 0.03800, 0.03490]})
df=df.replace("+/-", "±", regex=False)
print(df)
df.to_latex('232_a.txt', index=False, encoding="ISO-8859-1")
I'd appreciate any kind of help.我会很感激任何帮助。 Thanks in advance!提前致谢!
