Try to sleep on it or make a drawing of the program flow. Note: The @timer decorator is great if you just want to get an idea about the runtime of your functions. If you want to do more precise measurements of code, then you should instead consider the timeit module in the standard...
原始字符串:对于频繁使用到反斜杠的特殊字符串,一个一个去添加转义字符显得繁琐,可在字符串前面加上一个‘r’,这就是原始字符串的含义。例如字符串C:\Program File\Intel\WiFi\Help,定义只要r'C:\Program File\Intel\WiFi\Help',它的实现方法其实很简单,就是程序会自动对每一个反斜杠前面再加一个反斜杠。但...
