默认情况下,方法split()以空格(tab、换行)作为分割条件,对原字符串进行切割,最终返回一个字符串列表。我们用把这个列表赋值给另一个变量curs。 其实,我们可以用任意符号进行分割,继续来IDLE敲一下。 >>> port_vlan = 'port trunk allow-pass vlan 1843 1923 2033 2053 2103 2163 2273 2283' #原始字符串 >>...

字符串按照tab分割,8的倍数隔开,不足补空格---str.expandtabs() 就是来一个字符串,其间可能由\t分割,比如\t前面的字符串是3个字符,结果就是在后面自动补5个空格,接着就是原字符串\t后面的内容,如果原来字符串\t前面是10个字符,结果就是在\t位置补充6个空格(反正就是8的倍数,然后不空格就0k): ...

缩进可以用Tab键实现,也可以用多个空格实现(一般是4个空格),但两者不能混用。建议采用4个空格方式书写代码。 2.1.2 注释 注释是代码中的辅助性文字,会被编译器或解释器略去,不被计算机执行,一般用于程序员对代码的说明。Python语言中使用“#”表示一行注释的开始。注释可以在一行中任意位置通过“#...
