1. A function that requires one-step debugging is called in the script (a very important step). Since Python is an interpreted language, you need to tell the system that you are using this function when you are doing one-step debugging, and stepping into the function that you need. As shown, we define the CreateDataSet () function, which is called in the script before debugging, which is the red marked part.2. Add Breakpoints. As with the rest of the

A function is an encapsulation supported by Python. By splitting a large code segment into a function and calling a function at a layer, we can break down a complex task into a sim
(func)即可。Two: Partial function (one of functools the functions in the module)1在介绍函数参数的时候,通过设定参数的默认值,可以降低函数调用的难度。而偏函数也可以做到这一点。2 int() Functions can convert a string to an integer, and when passed in only the string, the int() function defaults to decimal conversion:int(‘12345‘)12345But int() the function also provides additional base parameters, the default value is 10 . If you pass in base a parameter, you can do an n-binary conversion: >>> int ( ' 12345 ', base= 8) 5349 #把字符串当做8进制 and returns t
