last = list(raw_input("Enter last name: "))

firstAndLast(first, last)

Answer 1

您可以setTimeout：-

import java.util.Scanner;

public class Facebook {


     public static void enterPassword() throws Exception {
            Scanner sc = new Scanner(System.in);
            String password;
            System.out.print("Enter your password : ");
            password = sc.next();
            // sc.close();
            if (!password.equals("incorrect")) {
                throw new Exception();
            }
        }

        public static void printPassword() {
            try {
                enterPassword();
            } catch (Exception e) {
                System.out.println("Your password is incorrect. Try again!");
                printPassword();
            }
        }

         public static void enterConfirmationCode() throws Exception {
                Scanner sc = new Scanner(System.in);
                String fiveDigits;
                System.out.print("Enter your 5 digits confirmation code : ");
                fiveDigits = sc.next();
                // sc.close();
                String getDigits  = fiveDigits.replaceAll("\\D+", "");
                if (getDigits.length() != 5) {
                    throw new Exception();
                }
            }

            public static void printConfirmationCode() {
                try {
                    enterConfirmationCode();
                } catch (Exception e) {
                    System.out.println("That's too long? Try again!");
                    printConfirmationCode();
                }
            }

        public static void main(String[] args) {


            System.out.println("Welcome to Facebook!");

            printPassword();
            printConfirmationCode();

            System.out.println("Congratulations, you have logged in to Facebook!");


        }

}

Answer 2

该错误告诉您该怎么做。在python-3.x中，print（）是带括号的函数，因此您必须在括号中传递参数。

$.ajax({
  type: "POST",
  url: "/contact",
  data: {
    myKey1: $("#myKey1").val(),
    myKey2: $("#myKey2").val()
  },
  beforeSend:function(){
  $(".loading_msg").hide();

  },
  complete:function(){
   $(".loading_msg").show();
   setTimeout(function(){
    console.log('Here')
    $(".loading_msg").fadeOut("slow");
    $("#message").val("")
   },3000)
  } 
});

您也可以只使用print(first)函数而不是input()函数

程序

raw_input()

输出

def firstAndLast(first,last):
    common = []
    for letter in first:
        if letter in last:
            common.append(letter)
    return common

first = input("Enter first name: ")
last = input("Enter last name: ")

common = firstAndLast(first, last)
#common will be the list of common letters

print(common)

Answer 3

程序：

s1=raw_input("Enter first string:")

s2=raw_input("Enter second string:")

a=list(set(s1)&set(s2))

print("The common letters are:")

for i in a:
    print(i)

Answer 4

s1 = input（“输入第一个字符串：”）

s2 = input（“输入第二个字符串：”）

a = list（set（s1）＆set（s2））

print（“常用字母为：”）

对于a中的i：print（i）

Answer 5

尝试一下

first = list(input("Enter first name: "))
last = list(input("Enter last name: "))

print(f"common characters are: {', '.join(set(first) & set(last))}")

输出：

Enter first name: Jaydip
Enter last name: Kyada
common characters are: a, y, d

我认为这一行会回答您的问题。

编写python程序以显示两个字符串之间的所有常见字符
