我试图在Python 3.2中创建一个应用程序,我一直使用制表符进行缩进,但即使是编辑器也将其中一些更改为空格,然后在我试图运行程序时打印出“在缩进中使用制表符和空格不一致”。

如何将空格改为制表符?快把我逼疯了。

import random

attraktioner = ["frittfall","bergodalbana","spökhuset"]


class Nojesfalt:
    def __init__(self, attraktion):
        self.val = attraktion
        self.langd = 0
        self.alder = 0


#längdgräns för fritt fall
    def langdgrans(self):
        print("")
        self.langd = int(input("Hur lång är du i cm? "))
        if self.langd < 140:
            print("tyvärr, du är för kort, prova något annat")
            return 0
        elif self.langd >= 140:
            print("håll dig hatten, nu åker vi!")
            print(" ")
            return 1

#åldersgräns för spökhuset
    def aldersgrans(self):
        print("")
        self.alder = int(input("Hur gammal är du? "))
        if self.alder < 10:
            print("tyvärr, du är för ung, prova något annat")
            return 0
        elif self.alder >= 10:
            print("Gå in om du törs!")
            print(" ")
            return 1


#åker attraktion frittfall lr bergodalbana
        def aka(self):
                print("")
        print(self.val)
        tal = random.randint(0,100)
        if tal < 20:
            print("åkturen gick åt skogen, bättre lycka nästa gång")
        elif tal >= 20:
            print("jabbadabbbadoooooooo")
            return 1

#går i spökhuset
        def aka1(self):
                print("")
        print(self.val)
        tal = random.randint(0,100)
        if tal < 20:
            print("du är omringad av spöken och kan inte fortsätta")            return 0
        elif tal >= 20:
            print("Buhuuuuuu, buuuhuuuu")
            return 1

#programkod
print("Välkommen till nöjesfältet, vad vill du göra?")
print(" ")

while 1:
    vald_attr = input("Vad vill du göra?\n1. frittfall\n2. bergodalbana\n3. spökhuset\n4. Avsluta\n")
    if vald_attr == "1":
        val = Nojesfalt(attraktioner[0])
        if val.langdgrans() == 1:
            val.aka()
    elif vald_attr == "2":
        val = Nojesfalt(attraktioner[1])
        val.aka()
    elif vald_attr == "3":
        val = Nojesfalt(attraktioner[2])
        if val.aldersgrans() == 1:
            val.aka1()
    elif vald_attr == "4":
        break

当前回答

我最近遇到了同样的问题,并发现我只需要将.py文件的字符集转换为UTF-8,因为这是Python 3使用的字符集。

顺便说一句,我一直使用4个空格制表符,所以问题不是由它们引起的。

如果你使用ATOM:

转到菜单:Packages——> WhiteSpace——>将所有制表符转换为空格

您的问题是由于您的编辑器限制/配置。一些编辑器通过以下方式为您提供工具来帮助解决问题:

将制表符转换为空格 例如,如果你正在使用Stani的Python编辑器,你可以配置它在保存时执行。 将空格转换为制表符

如果你正在使用ActiveState Komodo,你有一个工具来“tabify”你的代码。正如其他人已经指出的那样,这不是一个好主意。

Eclipse的Pydev提供了“将制表符转换为空格制表符”和“将空格制表符转换为制表符”函数。

对于VSCode用户

Ctrl+Shift+P或View->命令面板。

使用Vim编辑器解决这个问题

Open terminal (Ctrl + Alt + T). Go to the directory where the file is located (cd <path_to_your_directory>). Ex: cd /home/vineeshvs/work. Open the file in Vim (vim <file_name>). Ex: vim myfile.txt . [Optional step] Enable search keyword highlighting in Vim (ESC :set hlsearch) Go to the line where you have this problem (ESC :<line_number>). Ex: :53 in Vim editor after pressing ESC button once. Replace tabs using the required number of spaces in Vim (:.,$s/\t/<give_as_many_spaces_as_you_want_to_replace_tab>/gc). Ex: Tab will be replaced with four spaces using the following command: :.,$s/\t/ /gc after pressing ESC button once). This process is interactive. You may give y to replace the tab with spaces and n to skip a particular replacement. Press ESC when you are done with the required replacements.

There was a duplicate of this question from here but I thought I would offer a view to do with modern editors and the vast array of features they offer. With python code, anything that needs to be intented in a .py file, needs to either all be intented using the tab key, or by spaces. Convention is to use four spaces for an indentation. Most editors have the ability to visually show on the editor whether the code is being indented with spaces or tabs, which helps greatly for debugging. For example, with atom, going to preferences and then editor you can see the following two options:

然后,如果你的代码使用空格,你会在你的代码缩进的地方看到小点:

如果它使用制表符缩进,你会看到类似这样的东西:

Now if you noticed, you can see that when using tabs, there are more errors/warnings on the left, this is because of something called pep8 pep8 documentation, which is basically a uniform style guide for python, so that all developers mostly code to the same standard and appearance, which helps when trying to understand other peoples code, it is in pep8 which favors the use of spaces to indent rather than tabs. And we can see the editor showing that there is a warning relating to pep8 warning code W191,

我希望以上所有内容都能帮助您了解您所遇到的问题的性质,以及如何在将来预防它。
