1.4.3上的文件

Question

这是我的代码

sentext = open("urSentence.txt", "w") 
UserSen = input("Enter your sentence of your choice, ") 
print (UserSen) 
sentext.close() 
postext = open("ThePos.txt", "w") 
listSplit = UserSen.split() 
X = {} #this will make the words in a sentence assigned to a number 
position=[] 
for i,j in enumerate(listSplit): #"i" will count how many words there are in the sentence 
    if j in X: 
     position.append(X[j]) 
    else: 
     X[j]=i 
     position.append(i) 
print (position) 
postext.close() 

它使文件，但它不保存其中的任何东西。我究竟做错了什么？

Answer 1

你从来没有写过以任何方式任何文件。你可以用几种方法来做到这一点。既然你已经在使用什么样子的Python 3的print功能，尝试file参数：

print(UserSen, file=sentext) 

... 

print(position, file=postext) 

Answer 2

print函数不会写入文件。你需要明确地写信给它。

sentext = open("urSentence.txt", "w") 
UserSen = input("Enter your sentence of your choice, ") 
sentext.write(UserSen) 
sentext.close() 

和类似：

postext = open("ThePos.txt", "w") 
... 
postext.write(str(position)) 
postext.close()
