Answer 1

这是一个初学者的问题，可以通过在线python课程更好地解决。

但是，我会给你一个答案：

#Define your dictionary
Cities={"New York City":30, "Boston":54, "Los Angeles":75, "Orlando":114, "Houston":389, "Miami":200}

#Print the NY number
print(Cities["New York City"])

#Calculate the difference between the LA and Orlando numbers
difference = Cities["Los Angeles"] - Cities["Orlando"]

#Print the previously calculated difference
print(difference)
