将变量从第二个脚本返回到第一个脚本(Python)

def get_variable():
    variable = "Hello, World!"
    return variable

import script2

returned_variable = script2.get_variable()
print(returned_variable)  # 输出：Hello, World!

global_variable = "Hello, World!"

import script2

returned_variable = script2.global_variable
print(returned_variable)  # 输出：Hello, World!

variable = "Hello, World!"

with open("returned_variable.txt", "w") as file:
    file.write(variable)

with open("returned_variable.txt", "r") as file:
    returned_variable = file.read()

print(returned_variable)  # 输出：Hello, World!
