Python - 試圖添加註釋時出錯

Question

我正在學習如何將字符串，列表等寫入txt/dat文件。我想在我的代碼中添加註釋，以便我可以參考訪問密鑰的內容。所以這就是我所做的。

# Mode Description 
# rb  Read from a binary file. If the file doesn’t exist, Python will complain with an error. 
# wb  Write to a binary file. If the file exists, its contents are overwritten. If the file doesn’t exist, 
#  it’s created. 
# ab  Append a binary file. If the file exists, new data is appended to it. If the file doesn’t exist, it’s 
#  created. 
# rb+ Read from and write to a binary file. If the file doesn’t exist, Python will complain with an 
#  error. 
# wb+ Write to and read from a binary file. If the file exists, its contents are overwritten. If the file 
#  doesn’t exist, it’s created. 
# ab+ Append and read from a binary file. 

後，我有：

import pickle, shelve 

print("Pickling lists.") 
variety = ["sweet", "hot", "dill"] 
shape = ["whole", "spear", "chip"] 
brand = ["Claussen", "Heinz", "Vlassic"] 

f = open("pickles1.dat", "wb") 

pickle.dump(variety, f) 
pickle.dump(shape, f) 
pickle.dump(brand, f) 
f.close() 

print("\nUnpickling lists.") 
f = open("pickles1.dat", "rb") 
variety = pickle.load(f) 
shape = pickle.load(f) 
brand = pickle.load(f) 

print(variety) 
print(shape) 
print(brand) 
f.close() 

當我運行它，我得到以下錯誤：

語法錯誤：非UTF-8編碼與 '\ X92' 文件PickleIt開始.py在第10行，但沒有聲明編碼;詳情請見http://python.org/dev/peps/pep-0263/

我查了一下鏈接，但是我真的不明白，以前我沒看過。

Answer 1

將所有’替換爲'。 這是抱怨，因爲你沒有將編碼類型添加到文件的開頭。默認編碼是utf-8，其中不允許這些字符。

而不是取代的，你可以加入這一行開始（評論前）：

# coding: iso-8859-1

（或其他編碼，其中這些字符都存在，像latin-1例如。）

該行設置文件的編碼並允許使用特殊字符。
