First study python, Confused , Write a simple login verification , Take notes username = 'cc' # user name
userpassword = '123' # password
count = 0 # Counter
while count<3: # If the count is less than 3, Namely 0,1,2 Three times in total , Then execute the following code
_username = input("USER:")
_userpassword = input("PW:")
if _username == username and _userpassword == userpassword: # Judge whether the user name and password entered by the user are consistent
print("wlcome",username,"back.~~v-v".format(username=username))
break # If it is consistent, it will jump out of the loop
elif count<2:
print("not this user or password,try again")
count +=1
else:
print("lock!!!",username.format(username=username))
The code is simple , I hope I can write practical code in a year
