我最近开始学习Python和SQL，并有一个问题。

将Python与SQLite3结合使用，我编写了以下代码：

# Use sqlite3 in the file
import sqlite3

# Create people.db if it doesn't exist or connect to it if it does exist
with sqlite3.connect("people.db") as connection:
    c = connection.cursor()

    # Create new table called people
    c.execute("""CREATE TABLE IF NOT EXISTS people(firstname TEXT, lastname TEXT, age INT, occupation TEXT)""")


    people_list = [
        ('Simon', 'Doe', 20, 'Python Master'),
        ('John', 'Doe', 50, 'Java Master'),
        ('Jane', 'Doe', 30, 'C++ Master'),
        ('Smelly', 'Doe', 2, 'Shower Master')
    ]

    # Insert dummy data into the table
    c.executemany("""INSERT INTO people(firstname, lastname, age, occupation) VALUES(?, ?, ?, ?)""", people_list)

我注意到我可以使用for循环而不是executemany来做同样的事情：

# Use sqlite3 in the file
import sqlite3

# Create people.db if it doesn't exist or connect to it if it does exist
with sqlite3.connect("people.db") as connection:
    c = connection.cursor()

# Create new table called people
c.execute("""CREATE TABLE IF NOT EXISTS people(firstname TEXT, lastname TEXT, age INT, occupation TEXT)""")


people_list = [
    ('Simon', 'Doe', 20, 'Python Master'),
    ('John', 'Doe', 50, 'Java Master'),
    ('Jane', 'Doe', 30, 'C++ Master'),
    ('Smelly', 'Doe', 2, 'Shower Master')
]

# Insert dummy data into the table
for person in people_list:
    c.execute("""INSERT INTO people(firstname, lastname, age, occupation) VALUES(?, ?, ?, ?)""", person)

我只是想知道哪个更有效，更经常使用？
