如何在所有的dataframe python中将两个数字之间的'，‘替换为X.X%

import pandas as pd
import re

df = pd.DataFrame({'Column1': ['1,000', '2,500', '3,750'],
                   'Column2': ['4,500', '5,250', '6,000']})

def replace_comma(value):
    pattern = r'(\d+),(\d+)'
    replacement = r'\1.\2%'
    return re.sub(pattern, replacement, value)

df = df.applymap(replace_comma)

print(df)

  Column1 Column2
0  1.000%  4.500%
1  2.500%  5.250%
2  3.750%  6.000%
