python - 在 python 中，如何将一系列命令分配给一个变量？

Question

我通过深入研究自学python。如果你把它留空，我不确定一个函数是否会这样做：

#My first section that pulls a value from a random shuffle of codes
print "\n"
print "-"*10
print 'This is a test of the %s system'% codes[0]
print "-"*10
print "\n"

#My second section that pulls a value from a random shuffle of codes
print "\n"
print "-"*10
print 'This is not a test of the %s system and all is good'% codes[1]
print "-"*10
print "\n"

我的问题是，有没有办法让它看起来更好看，代码行更少？还是我坚持打印 10 行？

Answer 1

你可以使用一个函数：

def print_stuff(what,addendum=''):
    print "\n"
    print "-"*10
    print 'This is a test of the %s system%s' % (what,addendum)
    print "-"*10
    print "\n"

print_stuff(codes[0])
print_stuff(codes[1],addendum = " and all is good")

Answer 2

Python 有非常棒的多行字符串：

def print_it(somethig):
    print """
----------
This is a test of the {} system.
----------
""".format(something)

print_it(0)
print_it(1)

Answer 3

使用索引号创建一个函数：

def print_codes(i):
    #My first section that pulls a value from a random shuffle of codes
    print "\n"
    print "-"*10
    print 'This is a test of the %s system'% codes[i]
    print "-"*10
    print "\n"

print_codes(0)
print_codes(1)

如果要显示不同的消息，可以定义一个函数来接收要打印的消息：

def print_message(message):
    print "\n"
    print "-"*10
    print message
    print "-"*10
    print "\n"

print_message('This is a test of the %s system' % codes[0])
print_message('This is not a test of the %s system and all is good'% codes[1])
