Python语言采用严格的缩进来表示程序逻辑。也就是我们所说的Python程序间的包含与层次关系。一般代码不要求缩进,顶行编写且不留空白。在if、while、for、def、class等保留字所在完整语句后通过英文的“:”结尾并在之后行进行缩进,表明后续代码与紧邻无缩进语句的所属关系。
The program waits for you to select Ctrl+Z+Enter to close the window. Select File > Save (or Ctrl+S) to save the property changes. To attach the mixed-mode debugger to an existing process, select Debug > Attach to Process. A dialog opens. In the Attach to Process dialog, select ...
Then the program uses .read1() to try and read as many bytes as are available at .stdout. Note: If you put the Popen object into text mode and then called .read() on .stdout, the call to .read() would be blocking until it reached a newline. In this case, a newline would coi...

for循环在这个范围内递归——for i in range(1,5)等价于for i in [1, 2, 3, 4],这就如同把序列中的每 个数(或对象)赋值给i,一次一个,然后以每个i的值执行这个程序块。else部分是可选的。如果包含else,它总是在for循环结束后执行一次,除非遇到break语 句。 记住,for..in循环对于任何序列都适用。这...
