Question

好的，所以我有我的程序，但我得到一个“预期的缩进块”，我不知道它在哪里，我相信我说得对，但我很困惑。

##Cave fuction
def cave():

    global lvl
    global mhp
    global exp

    while True:
        print("Who whould you like to talk to. (Emily(1), James(2), Paco(3)")
        talk = int(input("Who to talk to: "))
        ptint(" ")               
        if talk == 1:
            #put storie function here
        elif talk == 2:
            #put train function here
        elif talk == 3:
            print("Your level is", lvl, "you have", mhp, "and have", exp, "EXP")
        else:
            amsterdam = 7 #filler

        print("Anthing else needed(y/n)")
        ant = input("Anthing: ")

        if ant == n:
            break
        else:
            mexico = 19 #filler

Answer 1

在if / elif语句之间放置pass（或print语句或真正执行的任何内容）。这些评论并不是真正的代码。

Answer 2

在Python中，C中没有像{}那样的空块。如果你想阻止什么都不做，你必须使用pass关键字。例如：

if talk == 1:
    pass  # Put storie function here.
elif talk == 2:
    pass  # Put storie function here.

这应该可以解决您的问题。在以:结尾的行之后，必须使用下一行，并且在这方面注释不计入缩进。

Answer 3

你必须在if-else语句中放入一些有效的语句，你写的是put storie function here。以下代码不会抛出错误，因为每个if-else都有一些有效的声明：

def cave():

    global lvl
    global mhp
    global exp

    while True:
        print("Who whould you like to talk to. (Emily(1), James(2), Paco(3)")
        talk = int(input("Who to talk to: "))
        ptint(" ")               
        if talk == 1:
            #put storie function here
            pass
        elif talk == 2:
            #put train function here
            pass
        elif talk == 3:
            print("Your level is", lvl, "you have", mhp, "and have", exp, "EXP")
        else:
            amsterdam = 7 #filler

        print("Anthing else needed(y/n)")
        ant = input("Anthing: ")

        if ant == n:
            break
        else:
            mexico = 19 #filler

Answer 4

在if或elif的条件之后，在else之后，预计会出现缩进块。像这样：

if condition:
    indented_block
elif condition:
    indented_block
else:
    indented_block

只是作为一个块的评论：

if condition:
    # ...

不考虑

，所以你必须把东西放在那里。另一种方法是使用占位符：

if condition:
    pass

pass是一个空操作。执行时没有任何反应。

Answer 5

如果这是你正在运行的确切代码，那么你的问题应该在：

while True:
    print("Who whould you like to talk to. (Emily(1), James(2), Paco(3)")
    talk = int(input("Who to talk to: "))
    ptint(" ")               
    if talk == 1:
        #put storie function here
    elif talk == 2:
        #put train function here

这里你得到的注释#put storie function here没有被评估为代码所以基本上python解释的是：

while True:
    print("Who whould you like to talk to. (Emily(1), James(2), Paco(3)")
    talk = int(input("Who to talk to: "))
    ptint(" ")               
    if talk == 1:
    elif talk == 2:
    […]

虽然它期望：

while True:
    print("Who whould you like to talk to. (Emily(1), James(2), Paco(3)")
    talk = int(input("Who to talk to: "))
    ptint(" ")               
    if talk == 1:
        print("python wants actual code here in an inner block")
    elif talk == 2:
        print("python wants actual code here in an inner block as well")
    […]

因而无法编译

Answer 6

你的if块是空的。试试这个

if talk == 1: pass #put storie function here elif talk == 2: pass #put train function here elif talk == 3: print("Your level is", lvl, "you have", mhp, "and have", exp, "EXP") else: amsterdam = 7 #filler

Answer 7

你需要在之前输入一些声明。 elif talk == 2:

if talk == 1:
    print 1
elif talk == 2:

Python：“预期的缩进块”不知道如何修复
