为什么这个打印函数在这里？

Question

我为这可能太简单而道歉，但我对这段代码的一个部分感到有点困惑。

# Geek Translator
# Demonstrates using dictionaries

geek = {"404": "clueless.  From the web error message 404, meaning page not found.",
        "Googling": "searching the Internet for background information on a person.",
        "Keyboard Plague": "the collection of debris found in computer keyboards.",
        "Link Rot" : "the process by which web page links become obsolete.",
        "Percussive Maintainance" : "the act of striking an electronic device to make it work.",
        "Uninstalled" : "being fired.  Especially popular during the dot-bomb era."}

choice = None
while choice != "0":

    print(
    """
    Geek Translator

    0 - Quit
    1 - Look Up a Geek Term
    2 - Add a Geek Term
    3 - Redefine a Geek Term
    4 - Delete a Geek Term
    """
    )

    choice = input("Choice: ")
    print()

    # exit
    if choice == "0":
        print("Good-bye.")

    # get a definition    
    elif choice == "1":
        term = input("What term do you want me to translate?: ")
        if term in geek:
            definition = geek[term]
            print("\n", term, "means", definition)
        else:
            print("\nSorry, I don't know", term)

    # add a term-definition pair        
    elif choice == "2":
        term = input("What term do you want me to add?: ")
        if term not in geek:
            definition = input("\nWhat's the definition?: ")
            geek[term] = definition
            print("\n", term, "has been added.")
        else:
            print("\nThat term already exists!  Try redefining it.")

    # redefining an existing term
    elif choice == "3":
        term = input("What term do you want me to redefine?: ")
        if term in geek:
            definition = input("What's the new definition?: ")
            geek[term] = definition
            print("\n", term, "has been redefined.")
        else:
            print("\nThat term doesn't exist!  Try adding it.")

    # delete a term-definition pair
    elif choice == "4":
        input("What term do you want me to delete?")
        if term in geek:
            del geek[term]
            print("\nOkay, I deleted", term)
        else:
            print("\nI can't do that!", term, "doesn't exist in the dictionary.")

    # some unknown choice
    else:
        print("\nSorry, but", choice, "isn't a valid choice.")

input("\n\nPress the enter key to exit.")

除了choice = input(Choice: ")之后的print()函数，我理解所有这些是如何工作的

那是怎么回事？如果我删除它，什么都不会改变(据我所知)，所以我对它的意义感到好奇。

Answer 1

没有参数的print()打印换行符。重点是显示终端输出中的空行。

Answer 2

它打印一个新行(在控制台输出中可以看到空行)。

Answer 3

一个空的print()输出一个换行符，所以可能它存在的唯一原因是添加一个换行符？
