Question

下面的代码每隔0.1秒逐个字母打印欢迎文本。

welcome = ("Welcome")

for character in welcome:
    print (character, end = "", flush = True)
    sleep(0.1)

通常，如果我想打印几件东西（在本例中为“欢迎”和“你好”），我会这样做：

welcome = ("Welcome")
hello = ("Hello")

for character in welcome:
    print (character, end = "", flush = True)
    sleep(0.1)

for character in hello:
    print (character, end = "", flush = True)
    sleep(0.1)

但是每次我想要换行时都键入此命令效率不高，因为这会浪费大量时间和空间。

for character in hello:
        print (character, end = "", flush = True)
        sleep(0.1)

有没有办法我只能以某种方式使用其中一个

for character in hello:
            print (character, end = "", flush = True)
            sleep(0.1)

要打印许多这样的行：

hello = ("How are You")
welcome = ("Welcome")
nice = ("Awesome")

Answer 1

您可以遍历存储所有消息的数组：

from time import sleep

hello = ("How are You")
welcome = ("Welcome")
nice = ("Awesome")

messages = [hello, welcome, nice]
for message in messages:
    for character in message:
        print (character, end = "", flush = True)
        sleep(0.1)
    print('')

输出如下所示：

你好吗

欢迎

太棒了

Answer 2

只需创建一个这样的函数

welcome = "Welcome"
hello = "Hello"

list = [welcome,hello]

def my_function(word):
    for character in word:
        print(character, end="", flush=True)
        sleep(0.1)

def my_function_list(list):
    for word in list:
        my_function(word)

my_function_list(list)

Answer 3

您可以定义一个功能。像这样一个：

def print_char_by_char(word): 
    for character in word:  
        print (character, end = "", flush = True)  
        sleep(0.1)

然后使用它：

print_char_by_char("How are You")
print_char_by_char("Welcome")
print_char_by_char("Awesome")

Answer 4

您可以定义和重用一个或两个函数，请检查以下代码：

def fancy_print(text):
    [print_and_wait(c) for c in text]

def print_and_wait(char):
    from time import sleep
    print(char, end='', flush=True)
    sleep(0.1)

if __name__ == '__main__':
    hello = "How are You"
    fancy_print(hello)

    welcome = "Welcome"
    fancy_print(welcome)

    nice = "Awesome"
    fancy_print(nice)

使用相同的3行代码打印多行
