如何将打印函数的输出重定向到pandas数据帧中？

import pandas as pd
import io
from contextlib import redirect_stdout

output = io.StringIO()
with redirect_stdout(output):
    # 在这里调用需要打印输出的函数

print('Hello, World!')

output_str = output.getvalue()

df = pd.DataFrame([output_str.split('\n')], columns=['Output'])

import pandas as pd
import io
from contextlib import redirect_stdout

def my_print_function():
    print('Hello, World!')
    print('This is a test.')

output = io.StringIO()
with redirect_stdout(output):
    my_print_function()

output_str = output.getvalue()
df = pd.DataFrame([output_str.split('\n')], columns=['Output'])
