import json
def getstoredname():
filename = 'username.json'
try:
with open(filename) as f:
username = json.load(f)
except:
return None
else:
return username
def getnewname():
username = input("What is your name? ")
filename = 'username.json'
with open(filename,'a+') as f:
json.dump(username,f)
return username
def greetuser():
username = getstoredname()
if username:
print("Welcome back, " + username + "!")
else:
username = getnewname()
print ("We'll remember you when you come back, " + username +
"!")
greetuser()
这个问题应该怎么改代码？
