如何在for循环中正确地将列表追加到DataFrame

import pandas as pd

df = pd.DataFrame()

data_list = [1, 2, 3, 4, 5]

for item in data_list:
    df = df.append({'Column_Name': item}, ignore_index=True)

print(df)

import pandas as pd

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

for item in data_list:
    df = df.append({'Column_Name': item}, ignore_index=True)

print(df)
