一个 print("Hello world!") 能玩出几个花样

普普通通式

print("Hello world!")

变量式

text = "Hello world!"
print(text)

函数式

def sayhello():
        print("Hello world!")
sayhello()

模块式
a.py:

def main():
                print("Hello world!")

b.py:

import a
a.main()

参数式

def sayhello(x):
        print(x)
sayhello("Hello world!")

类式

class IO:
    def out(self,text):
        print(text)

stdio = IO()
stdio.out('Hello, World!')

Tensorflow 式

import tensorflow as tf
hello = tf.constant("Hello world!")
sess = tf.Session()
h = sess.run(hello)
print(h.decode())

无 print() 式

#myhello.py
import sys
from time import time
from os import system
def _output(string):
    try:
        for i in string:
            sys.stdout.write(i)
            sys.stdout.flush()
        sys.stdout.flush()
        return 0
    except:
        return 1

class my_io(object):
    def __init__(self):
        self.string = '\0'
    def output(self):
        return _output(self.string)
        
def main():
    global text, mio, errno
    errno = 0
    text = 'Hello World!'
    mio = my_io()
    mio.string = text
    if mio.output():
        errno = 1
        return 1
    return 0

if __name__ == '__main__':
    st = time()
    main()
    en = time()
    exit_output = my_io()
    exit_output.string = f"\n--------------------------------\nProcess exited after {round(en - st, 3)} seconds with return value {errno}\n请按回车继续..."
    exit_output.output()
    sys.stdin.readline()
    sys.exit(errno)

ASCII 编码 + 解包式

print(*[chr(len(' a a a a  a a a a a '.split(' ')[i])*100+len('aaaaaaa    a aaa a a a   aaa'.split(' ')[i])*10+len('aa a aaaaaaaa aaaaaaaa a aa aaaaaaaaa a aaaa aaaaaaaa  aaa'.split(' ')[i])) for i in range(12)], sep = '')

彩蛋式

import __hello__

瞧瞧，一个 Hello world 能玩出多少花样，我们在写程序时也不能一根筋的去写
牢记：条条大路通罗马！

青出于蓝

class IO:
    def out(self,text):
        print(text)

stdio = IO()
stdio.out('Hello, World!')

>>> print(*[chr(len(' a a a a  a a a a a '.split(' ')[i])*100+len('aaaaaaa    a aaa a a a   aaa'.split(' ')[i])*10+len('aa a aaaaaaaa aaaaaaaa a aa aaaaaaaaa a aaaa aaaaaaaa  aaa'.split(' ')[i])) for i in range(12)], sep = '')
Hello world!

ASCII码是吧
