download:Vue3 master a complete knowledge system from entry to actual combat

Who says zero-based classes are shallow? This course will bring you an easy introduction, in-depth mastery of Vue3 and solid front-end skills. From Vue3 basic grammar, to component principle, animation, code design, and then to the extension of new grammar, the course comprehensively and systematically combs Vue knowledge points from simple to deep. In the learning process, there are teachers for many years of “avoid pit experience” to teach each other, and in the end, take you according to the enterprise level code quality and engineering development process to complete the application of “Jingdong Home”, to achieve a thorough grasp of the framework.

Suitable for people who want to start from scratch to get a thorough introduction to Vue; Those who want to understand the principle and new syntax of Vue3; Students who want to expand their front-end knowledge and seek promotion and salary opportunities should be familiar with BASIC JS grammar. Understand the Npm development environment; Understand basic Webpack operations

Randrange (0,4) =i and index +1 ! = I: 7 checkCode += CHR (random.randint(97,122)) # generate a lowercase letter in a z 8 elif index +1== I: 9 checkcode += CHR (random.randint(65,90)) # generate A capital letter in A~Z 10 else: 11 print(checkCode) (m47A, 8wQ9, vugS

2. Formatting time function

3 import time4 return time.strftime(“%Y-%m-%d “) 3 def formatTime(longtime): longtime 3 import time4 return time.strftime(“%Y-%m-%d %H:%M:%S”,time.localtime(longtime))

3. Record the display log instance

Import time def show_info(): print(” “) def write_loginfo(username): print(” “) def write_loginfo(username): Param username: username “”” with open(‘log.txt’,’a’) as f: String = “User name: {} Login time: {}\n”.format(username ,time.strftime(‘%Y-%m-%d %H:%M:%S’,time.localtime(time.time()))) f.write(string) def Read_loginfo (): “”” “”” “”” with open(‘log.txt’,’r’) as f: while True: line = f.readline() if line == “: Print (line) # if name == “main”:

Enter a user name

While len(username) < 2: Print (' username = 1 ') print(' username = 1 ') print(' username = 1 ') print(' username = 1 ') print(' username = 1 ') print(' username = 2 ') Print (' Password should be at least 6 characters long ') password = input(' Please enter password: Num = int(input(' ') print(' ') print(' ') write_loginfo(username) If num == 0: print(' num ') break elif num == 1: Print (' print ') read_loginfo() show_info() num = int(input(' print ') else: Print (' print ') show_info() num = int(input(' print ')Copy the code

3. 3 def find_answer(question): 4 with open(‘reply.txt’,’r’) as f: 5 while True: 6 line=f.readline() 7 if not line: # can also for the if the line = = 9 ‘8 break keyword = line. The split (‘ |’) [0] 10. Reply = line split (‘ | ‘) [1] 11 if keyword in question: 15 if name ==’main’: 16 question=input(‘ please input what you want to ask: ‘) 17 while True: 18 if question==’bye’: 19 break 20 reply=find_answer(question) 21 if not reply: 22 question=input(” I don’t know what you are talking about, you can ask something about order, account and payment (to exit please enter bye) : “) 24 print(reply) 25 question=input(” You can ask something about order, account and payment (please enter bye to exit) : “) ‘) 27 Copy code Copy code 4. Find the maximum number of treaties and least common multiple (division by toss and turn) Maximum number of treaties: refers to two or more integers common divisors of the largest

Least common multiple: The common multiple of two or more integers is called their common multiple, where the least common multiple other than 0 is called the least common multiple of the integers

Relation: Product of two numbers = least common multiple * maximum treaty number

1 a=int(input(‘ input 1:’)) 2 b=int(input(‘ input 2:’)) 3 s=a*b 4 while a%b! =0: 5 a,b=b,(a%b) 6 print(a) 7 print(b) 8 else:
