Python制作英⽂学习词典编写程序制作英⽂学习词典，实现3个基本功能。添加，查询和退出。
以下是该词典的Python代码：
dict = {}
digits = '0123456789'
path = ''
def readFile(path, arg):
try:
file = open(path,arg,encoding = "utf-8")
except:
file = open(path,'w',encoding= "utf-8")呕心沥血
return file
def readWords():
file = readFile(path, 'r')
while True:
line = adline()
if not line:
break
word = line.split(' ',2)
dict[word[0]] = word[1][:-1]
file.clo()
def writeFile(word,dsp):
file = readFile(path,'a')
file.write('{} {}\n'.format(word, dsp))
file.clo()
def modifyFile(word, dsp):
冲绳岛file = readFile(path,'r')

flen = len(line) -1
for i in range(flen):
if word in line[i]:
file.clo()
line[i] = '{} {}\n'.format(word, dsp)
file = readFile(path,'w')
file.writelines(line)
break
file.clo()
