Normally, when you create a variable inside a function, that variable is local, and can only be used inside that function. 通常,在函数内部创建变量时,该变量是局部变量,只能在该函数内部使用。 To create a global variable inside a function, you can use the global keyword. 要在函数内部创建全局变...

A rocket ship goes through several steps before a launch. Depending on tasks or delays, these steps might take longer than planned. Let's create a variable-length function that can calculate how many minutes until launch, given how much time each st...
