1.4.3上的文件

Question

這是我的代碼

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東西。我究竟做錯了什麼？

Answer 1

你從來沒有寫過以任何方式任何文件。你可以用幾種方法來做到這一點。既然你已經在使用什麼樣子的Python 3的print功能，嘗試file參數：

print(UserSen, file=sentext) 

... 

print(position, file=postext) 

Answer 2

print函數不會寫入文件。你需要明確地寫信給它。

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

和類似：

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