什么是"AttributeError:"_ io.TextIOWrapper"对象没有属性"replace"在python中? [英] What is a " AttributeError: '_io.TextIOWrapper' object has no attribute 'replace' " in python?

问题描述

print (
"""    Welcome to the code breaker game!
       In this game you will have to change symbols into letters in order to decipher secret words. 
       0 - instructions
       1 - start
       2 - clues
       3 - check your answers
       4 - quit
""")

choice = input(" choice : ")

if choice == ("0"):
    text_file = open ("instructions.txt","r")
    print (text_file.read())
    text_file.close()

elif choice =="1":
    text_file = open ("words.txt","r")
    contents = text_file
    print (text_file.read())
    text_file.close()
    a = input("Please enter a symbol ")
    b = input("Please enter a letter ")

    newcontents = contents.replace(a,b)
    contents = newcontents
    print(contents,"\n")
    text_file.close


elif choice == "2":
 text_file = open ("clues.txt","r")
 print (text_file.read())
 text_file.close()

elif choice == "3":
 text_file = open ("solved.txt","r")
 print (text_file.read())
 text_file.close()

elif choice == "4":
 quit 

所以基本上我正在做一个计算机科学项目，我的任务是通过将符号替换为字母来制作解码游戏，但是当我尝试制作实际上将符号变成字母的代码部分时，却遇到了这个错误.

So basically I'm doing a computer science project and my task is to make a decoding game by substituting symbols to letters but I get this error for when I try to make the part of the code which actually changes symbols into letters.

还有什么方法可以使该循环(不使用while循环，因为它们非常复杂)?我基本上希望代码在运行程序时向我显示A和B，并在选择任何选项后为我显示能够选择其他选项的代码. (例如，我按0进行说明，然后可以选择其他选项，例如开始游戏.)

Also is there any way to make this loop (not using while loops as they are quite complicated)? I basically want the code to show me the A and B when I run the program and for me after choosing any option to be able to choose a different option. (Eg I press 0 for instructions and then be able to choose a different option such as start game).

推荐答案

这部分代码:

text_file = open ("words.txt","r")
contents = text_file
print (text_file.read())
text_file.close()

没有任何意义.您正在将文件对象(不是文件内容的 )分配给contents.然后，您print内容，但不要将其分配给任何内容.我想您想要的是:

makes no sense. You are assigning the file object (not the file's contents) to contents. You then print the contents, but don't assign them to anything. I think what you want is:

with open("words.txt") as text_file:
    contents = text_file.read()
print(contents)
