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。
Shorthand if and if else is nothing but a way to write the if statements in one line when we have only one statement to execute in the if block and the else block. An example for shorthand if in Python: Python 1 2 3 a = 4 b = 2 if a>b: print(" a is greater than b") ...

To use the if-else in one line in Python, we can use the expression: a if condition else b. In this expression, a is evaluated if the condition is True. If the condition is false, then b is evaluated. Let us use this as an example. Syntax of if else in one line 1 2 3 4...
