将变量值从一个文件写入另一个文件

# 定义变量值
variable_value = "Hello, World!"

# 源文件路径
source_file_path = "source.txt"

# 目标文件路径
target_file_path = "target.txt"

# 从源文件读取变量值
with open(source_file_path, 'r') as source_file:
    variable_value = source_file.read()

# 将变量值写入目标文件
with open(target_file_path, 'w') as target_file:
    target_file.write(variable_value)
