Question

我正在尝试制作一个读取指定文本文档的基本脚本，要求替换一串字符以及替换它，然后保存它：

from tkinter import Tk, filedialog
from tkinter.filedialog import askopenfilename

Tk().withdraw()
    def OpenFile():
    fileName = askopenfilename(initialdir="C:/Users", filetypes = (("Text File", "*.txt"),("All Files","*.*")), title = "Open a document.")
    with open(fileName, 'r') as f:
        textFile = f.read()

OpenFile()
print(textFile)

运行脚本并选择文件

时出错

Traceback (most recent call last):
  File "C:\Users\****\Documents\Python\Find and Replace\replace.py", line 11, in <module>
print(textFile)
NameError: name 'textFile' is not defined

Answer 1

游戏：找到不同的东西：

from tkinter import Tk, filedialog
from tkinter.filedialog import askopenfilename

Tk().withdraw()

def OpenFile():
    fileName = askopenfilename(initialdir="C:/Users", filetypes = (("Text File", "*.txt"),("All Files","*.*")), title = "Open a document.")
    with open(fileName, 'r') as f:
        textFile = f.read()
        return textFile # RETURN THE FILE CONTENT HERE SO IT IS VISIBLE TO THE MAIN FUNCTION

textFile = OpenFile() # GET YOUR OUTPUT HERE SO YOU CAN PRINT IT ON THE NEXT LINE
print(textFile)

读取文本文档并将其转换为字符串
