使用Python、Java、C++、C、C#等分别来实现下面功能的完整代码，功能：
小红书、知乎、百度、公众号等多平台选择模块：Python代码：
“`python
def select_platform():
print(“请选择要发布的平台：”)
print(“1. Windows”)
print(“2. Linux”)
print(“3. macOS”)
choice = input(“请输入对应的数字（1/2/3）：”)
if choice == “1”:
return “Windows”
elif choice == “2”:
return “Linux”
elif choice == “3”:
return “macOS”
else:
print(“输入错误，请重新输入！”)
return select_platform()
platform = select_platform()
print(“您选择的平台是：”, platform)
