所以我正在制作一个程序，可以根据需要多次向用户重复问候语，但是当他们想继续时，它不会显示该代码

Question

print("This program will print the amount of greeting you would like to see.")
print()
play = input("Do you want to continue? (y/n): ") 
while play == "y":
    name = input("Enter your name: ")
    print()
    greetings = int(input("How many times would you like to see your custom greeting?: "))
    print()
    for i in range(greetings):
        print("Hello " + name + "." + " It's a pleasure to meet you!")
    while play == "n":
        continue

所以在这一行中它没有显示 would you like to see more，而是显示 Enter your name。我不确定是否应该删除此代码或更改某些内容

        play_2 = input("Would you like to see more? (y/n): ")
        while play_2 == "y":
            name_2 = input("Enter your name: ")
            print()
            greetings_2 = int(input("How many times would you like to see your custom 
greeting?: "))
            print()
            for i in range(greetings_2):
                print("Hello " + name_2 + "." + "It's a pleasure to meet you!")
            while play_2 == "n":
                continue

print()                 
print("Bye. Thanks for using my program!")

Answer 1

        play_2 = input("Would you like to see more? (y/n): ")
        while play_2 == "y":
            name_2 = input("Enter your name: ")
            print()
            greetings_2 = int(input("How many times would you like to see your custom 
greeting?: "))
            print()
            for i in range(greetings_2):
                print("Hello " + name_2 + "." + "It's a pleasure to meet you!")
            while play_2 == "n":
                continue

取消缩进一次。我建议先进行调试。

Answer 2

您可以按如下方式更改代码：

print("This program will print the amount of greeting you would like to see.")
print()
play = input("Do you want to continue? (y/n): ") 
while play == "y":
    name = input("Enter your name: ")
    print()
    greetings = int(input("How many times would you like to see your custom greeting?: "))
    print()
    for i in range(greetings):
        print("Hello " + name + "." + " It's a pleasure to meet you!")
    play = input("Would you like to see more? (y/n): ")

问题出在 while 循环的设置上。如果用户想在最后再次运行该程序，则只需要一个检查。如果用户输入除“y”以外的任何内容，循环将中断。

Answer 3

您需要一种重复输入的机制，Do you want to continue? (y/n):例如在下面的代码中，它已被放入 while 循环中，因此它会在打印给定名称指定次数后再次运行。

print("This program will print the amount of greeting you would like to see.")
print()

play = input("Do you want to continue? (y/n): ")

while play == "y":
    name = input("Enter your name: ")
    greetings = int(input("How many times would you like to see your custom greeting?: "))
    for i in range(greetings):
        print("Hello " + name + "." + " It's a pleasure to meet you!")
    play = input("Do you want to continue? (y/n): ")

样本运行:

This program will print the amount of greeting you would like to see.

Do you want to continue? (y/n): y
Enter your name: Naomi
How many times would you like to see your custom greeting?: 2
Hello Naomi. It's a pleasure to meet you!
Hello Naomi. It's a pleasure to meet you!
Do you want to continue? (y/n): y
Enter your name: Campbell
How many times would you like to see your custom greeting?: 2
Hello Campbell. It's a pleasure to meet you!
Hello Campbell. It's a pleasure to meet you!
Do you want to continue? (y/n): n

Process finished with exit code 0

Answer 4

使用 while True 的无限循环，如果用户不想继续，则使用 break 离开。这样做的好处是您不必在多行代码中跟踪额外的变量。

print("This program will print the amount of greetings you would like to see.")
while True:
    name = input("Enter your name: ")
    number_of_greetings = int(input("How many times would you like to see your custom greeting?: "))
    for _ in range(number_of_greetings):
        print(f"Hello {name}. It's a pleasure to meet you!")
    play_again = input("Do you want to continue? (y/n): ")
    if play_again != 'y':
        break

print("Bye. Thanks for using my program!")

Answer 5

print("This program will print the amount of greeting you would like to see.")
while (play := input("\nDo you want to continue? (y/n): ")).lower() == "y" :
    name = input("Enter your name: ")
    print()
    greetings = int(input("How many times would you like to see your custom greeting?: "))
    print()
    for i in range(greetings):
        print("Hello " + name + "." + " It's a pleasure to meet you!")

您可以通过对输入添加检查并在字符串末尾使用 \n 来消除 print() 行从而减少代码的长度来改进代码。

So I'm making a program that repeats a greeting to the user as many times they want, but when they want to continue it doesnt show that code

python

for-loop

while-loop
