PySnooper支持灵活多样的程序调试,包括但不限于:给函数添加装饰器@pysnooper.snoop(),完成对函数的监听。 使用with pysnooper.snoop()语句,实现对程序块(block),即一行或者多行程序进行监听。 使用@pysnooper.snoop(‘/my/log/file.log’),将监听结果重定向到文件系统。 监听非局部变量的值: @pysnooper.snoop(vari...
Inside the Python interpreter, the help() function pulls up documentation strings for various modules, functions, and methods. These doc strings are similar to Java’s javadoc. The dir() function tells you what the attributes of an object are. help展示function之类的documentation dir显示object的属...

When referring to multiple variables parenthesis is used. Example: str1 = 'World' str2 = ':' print("Python %s %s" %(str1,str2)) Output: Python World : Repeating Characters Use multiplication with strings to repeat characters: print('#' * 10) # Output: ### Other Examples...
python中print一个方法后面输出多一个none 在使用python,如果方法中有输出结果,那么直接调用方法即可输出相应结果 (虽然是多此一举的输出和最简单的代码) 是因为python中的方法如果没有写返回值,那么默认返回的none,感觉python真是一切方便为主... 查看原文 Python中如何从列表中删除None值 在Python中我们可以使用...
