如何创建一个迭代列表的函数，同时在数据帧中创建一个新列？

import pandas as pd

df = pd.DataFrame()
my_list = [1, 2, 3, 4, 5]

for item in my_list:
    df['new_column'] = item

import pandas as pd

def create_iterative_list(my_list):
    df = pd.DataFrame()
    for item in my_list:
        df['new_column'] = item
    return df
