試圖在python中比較兩個字符串

Question

我什至在使用print語句檢查y.name和收藏夾時是否相同，但是使用它們時仍然沒有輸入if語句

if y.name == favourite 

要么

if favourite ==y.name

我對為什么這樣做感到非常困惑，因為我認為這只是一個標准的相等性檢查（代碼的開頭大部分是設置好的，在出現問題的情況下僅將其包括在上下文中，而不是if語句）。 先感謝您！

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)

我認為您應該在比較兩個字符串之前添加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)
