python - 尝试在 python 中比较两个字符串

Question

我什至在检查时使用 print 语句来检查 y.name 和 favorite 是否相同，但在使用

时仍然没有输入 if 语句

if y.name == favourite 

或

if favourite ==y.name

我非常困惑为什么会这样，因为我认为这只是一个标准的相等性检查(代码的开头大部分已设置，只是将其包含在上下文中，以防出现问题而不是问题) if 语句)。预先感谢您!

class Anime(object):
    name: str = ""
    year_aired = 0
    genre1: str = ""

    def __init__(self, name, genre1, year_aired):
        self.name = name
        self.genre1 = genre1
        self.year_aired = year_aired


def _make_anime(name, genre1, year_aired):
    anime = Anime()
    return anime


animelist = input("Please enter a file with a list of anime\n")
animel = open(animelist, "r")
nolines = animel.readlines()
animearr = []
numanime = -1
for i in nolines:
    if i.find("*") != -1:
        animearr[numanime].genre1 = i
    else:
        k = Anime("","", 2018)
        k.name = i
        animearr.append(k)
        numanime += 1
favourite = input("Please enter your favourite anime\n")
favgenre = ""
for y in animearr:
    if y.name == favourite:
        favgenre = y.genre1
print(favgenre)

我认为你应该在比较两个字符串之前添加 strip.("\n") 。

class Anime(object):
    name: str = ""
    year_aired = 0
    genre1: str = ""

    def __init__(self, name, genre1, year_aired):
        self.name = name
        self.genre1 = genre1
        self.year_aired = year_aired


def _make_anime(name, genre1, year_aired):
    anime = Anime()
    return anime


animelist = input("Please enter a file with a list of anime\n")
animel = open(animelist, "r")
nolines = animel.readlines()
animearr = []
numanime = -1
for i in nolines:
    if i.find("*") != -1:
        animearr[numanime].genre1 = i
    else:
        k = Anime("","", 2018)
        k.name = i
        animearr.append(k)
        numanime += 1
favourite = input("Please enter your favourite anime\n")
favgenre = ""
for y in animearr:
    if y.name == favourite.strip("\n"):

        favgenre = y.genre1
print(favgenre)
