文本文档中的字符串不等于程序中的相同字符串

Question

此代码的目标是要求编号1-41，在文本文档中查找该特定数字行，并检查它是否等于字符串＆＃39; good＆＃39;。< / p>

f = open("Goods", "r") #Opens the "Goods" file
lines = f.readlines() #Loads all 42 lines into memory

x = int(input("pick a number 1-41")) #asks for a number 1-41, casts it to an int, and assigns it to 'x'

if x < 13:
    goods = "Lumber"
elif x > 12 and x < 22:
    goods = "Spices"
elif x > 21 and x < 33:
    goods = "Fruit"
elif x > 32 and x < 41:
    goods = "Rum"
else:
    goods = "Opium"

if lines[x] == string:
    print("It worked!")
else:
    print(string, lines[x])  
#prints both the string, and the line gotten from the text document for trouble shooting
    print("Fail")

然而，这段代码的问题在于，即使文本文档中的行和字符串“＆＃39; goods＆＃39;完全一样; python没有看到，而是执行else语句。

如何让python将两个字符串注册为相同的？
