class number: #This is an example of block of code where the block consists of an entire class def __init__(self,value): self.value =value def increment(self): self.value=self.value+1 Generally, a block of code extends to multiple lines. So to comment out a block of code in pyth...

When you define return_42(), you add an explicit return statement (return 42) at the end of the function’s code block. 42 is the explicit return value of return_42(). This means that any time you call return_42(), the function will send 42 back to the caller....
Currently, tabs are restricted to four spaces due to TclTk limitations 在block opening语句之后,下一行将缩进4个空格(在Python Shel窗口中缩进一个选项卡)。在某些关键字(break、 return等)之后,下一行是dedented。在前导缩进中,退格删除最多4个空格(如果有)。Tab插入空格(在Python Shell窗 口的一个Tab中)...
一、定义模块: 模块:用来从逻辑上组织python代码(变量、函数、类、逻辑:实现一个功能),本质就是以.py结尾的python文件(文件名:test.py ,对应的模块名就是test) 包:用来从逻辑上组织模块的,本质就是一个目录(必须带有__init__.py的文件)二、导入方法: 1、impo
15、This technique of using the values of outside parameters within a dynamic function is called closures. 16、The with statement creates what’s called a context: when the with block ends, Python will automatically close the file, even if an exception is raised inside the with block. ...
