请回答t给出的问题他顶了...谢谢



我需要让my_glossary从txt文件中获取数据但是当我使用addNewWord函数添加数据时，我会收到诸如txt文件中的语法错误，指出{}或''是问题的原因。

please answer the question given at the top...thanks

I need to get my_glossary to get the data from the txt file but when I add the data using the addNewWord function I get errors such as a syntax error inside the txt file saying that the {} or '' are the cause of the issue.

from tkinter import *

def dictest():
    global my_glossary
# read all lines of the file
    inFile = open("glossary.txt", "r")
    inText = inFile.read()
    inFile.close()
 
    my_glossary = {}
# iterate through all lines, after removing the line-end character(s)
    for line in inText.splitlines():
        if line != '':           # ignore empty lines
            key,value = line.split(',')
            my_glossary[key] = value
 
    my_glossary['newkey'] = 'and the new value'
 
# list all the dictionary entries
    for k,v in my_glossary.items():
        print('key:', k, ', value:', v)

# key press funciton:
def click():
    entered_text = entry.get() # collect text from the text entry box
    output.delete(0.0, END) # clear text box
    try:
        definition = my_glossary[entered_text]
    except:
        definition = "There is no entry for this word."
    output.insert(END, definition)

def clickNew():
    global my_glossary
    addToGlossary = entryNew.get()
    addToGlossaryDef = outputNew.get()
    my_glossaryOpen = open("glossary.txt", "a")
    #addToGlossaryTotal = {
        #addToGlossary : addToGlossaryDef 
        #}
    addToGlossaryTotal = addToGlossary, addToGlossaryDef,
    my_glossaryOpen.write(repr(addToGlossaryTotal))
    my_glossaryOpen.close()

推荐答案

请参阅以下内容阅读文本文件和创建字典。请注意，词汇表文件中的文本不需要引号。我的文件看起来像：

See the following for reading the text file and creating a dictionary. Note you do not need quotes around your text in the glossary file. My file looks like:

foo,something silly
bar,something sillier

代码

Code

f = open('glossary.txt','r')
line = f.readline()
words = line.split(',')
dict = {}
dict[words[0]]=words[1]
line = f.readline()
words = line.split(',')
dict[words[0]]=words[1]

dict    # show the dictionary content

# output
{'foo': 'something silly\n', 'bar': 'something sillier\n'}

def dictest():
# read all lines of the file
    inFile = open("glossary.txt", "r")
    inText = inFile.read()
    inFile.close()

    glossary = {}
# iterate through all lines, after removing the line-end character(s)
    for line in inText.splitlines():
        if line != '':           # ignore empty lines
            key,value = line.split(',')
            glossary[key] = value

    glossary['newkey'] = 'and the new value'

# list all the dictionary entries
    for k,v in glossary.items():
        print('key:', k, ', value:', v)
