I get the error saying "TypeError: expected string or bytes-like object" how do I fix this?

Question

words = ['apple','bear','cinema']
dataset2 = ['apple','apple','bear','bear','pooh','cinema','cinema']
final_keys = {'apple':'a,b,c,d,b','bear':'s,q,d,f,d,s,d', 'cinema':'a,q,v,d,s,'}

for word in words:
    for i in range(len(dataset2)):        
        if word == str(dataset2[i]):
            datatocopy = final_keys[word]
            # above is where I get the error from

            load_ws[i+1,4] = str(datatocopy)
        else:
            continue

以上是我的部分代码。我从 datatocopy = final_keys[word] 收到错误说 TypeError: expected string or bytes-like object.。有帮助吗？

我检查了你的代码，你提到的抛出错误的那一行工作正常。这是我试过的：-

words = ['apple','bear','cinema']
dataset2 = ['apple','apple','bear','bear','pooh','cinema','cinema']
final_keys = {'apple':'a,b,c,d,b','bear':'s,q,d,f,d,s,d', 'cinema':'a,q,v,d,s,'}

for word in words:
    for i in range(len(dataset2)):        
        if word == str(dataset2[i]):
            datatocopy = final_keys[word]
            print("Values : ", datatocopy)
            # above is where I get the error from

            # load_ws[i+1,4] = str(datatocopy)
        else:
            continue

这是输出：

Values :  a,b,c,d,b
Values :  a,b,c,d,b
Values :  s,q,d,f,d,s,d
Values :  s,q,d,f,d,s,d
Values :  a,q,v,d,s,
Values :  a,q,v,d,s,

I get the error saying "TypeError: expected string or bytes-like object" how do I fix this?
