如何在python中重用前导码？

def print_header():
    print("This is the header.")

def print_footer():
    print("This is the footer.")

def print_content(content):
    print("This is the content:", content)

# 在需要使用前导码的地方调用函数
print_header()
print_content("Hello, world!")
print_footer()

# mymodule.py
def print_header():
    print("This is the header.")

def print_footer():
    print("This is the footer.")

def print_content(content):
    print("This is the content:", content)

import mymodule

mymodule.print_header()
mymodule.print_content("Hello, world!")
mymodule.print_footer()
