Python 2.7.13 多行打印

Question

这是一个初学者问题。我正在写一个文字游戏，遇到了一些问题。

代码：

def river():
    print "You are traveling through deciduous forest."
    print "There is nothing going on, except a few squirrels and a hedge."
    print "Squirrels are fighting over nuts and a hedge is getting fat eating an apple."
    print "Then you see a wide, deep river. The stream is very strong."
    print "What are you going to do next?"
    print "1. Try to swim the river."
    print "2. Watch the squirrels and hedge."
    print "3. Turn back."

    while True:
        choice = raw_input("> ")

        if choice == "1" or choice == "swim":
            print """You are doing well when in the middle of a river
something begins to bite you near legs. The bitting gets stronger
and you soon realize that piranhas are tearing chunks of your meat
off. Soon there is nothing left of you that the bones. The piranhas
seems satisfied, since they got a free meal."""
            dead()
        if choice == "2" or choice == "watch":
            print "You keep watching animals and are becoming more and more thirsty and hungry."
        if choice == "3" or choice == "turn back" or choice == "turn":
            start_rewind()

start()

我不喜欢这些打印语句。如果我使用多行打印，就像选择 1 一样，缩进看起来不太好。它与 def river() 在同一行。这是正常的还是坏的风格？如果我缩进选项 I 下的文本，那么它与选项 1 在同一行，.. 那么当我在命令提示符中启动脚本时它看起来不太好。我该如何解决？

谢谢

Answer 1

我会这样写：

print ("You are traveling through deciduous forest.\n"
       "There is nothing going on, except a few squirrels and a hedge.\n"
       "Squirrels are fighting over nuts and a hedge is getting fat eating an apple.\n"
       "Then you see a wide, deep river. The stream is very strong.")

上面的括号隐含地延续了字符串。参见 the Python docs。例如：

print ("foo "
       "bar")

和print "foo bar"

将给出相同的输出。注意 "foo".

之后的 space

注意在print语句和第一个括号之间有一个space。在python3中，print是一个函数，那里应该没有space。

Answer 2

试试这个：

print("""
You are traveling through deciduous forest.
There is nothing going on, except a few squirrels and a hedge.
Squirrels are fighting over nuts and a hedge is getting fat eating an apple.
Then you see a wide, deep river. The stream is very strong.
What are you going to do next?
1. Try to swim the river.
2. Watch the squirrels and hedge.
3. Turn back.
""")
