if is_sunny: print("It's a nice day!") else: print("It's a bit warm but cloudy.") else: print("It's cool outside.") 三元运算符 Python 还支持三元运算符(条件表达式),用于简化简单的 if-else 语句。 语法: python value_if_true if condition else value_if_false 示例: python age = ...
If `condition` is a string (e.g. ‘${rc} < 10’), it is evaluated as a Python expression using the built-in ‘eval’ function and the keyword status is decided based on the result. If a non-string item is given, the status is got directly from its truth value. 由上文可知condit...
下面是一个示例,演示如何使用逻辑运算符计算多个"True"值: 代码语言:python 代码运行次数:0 复制Cloud Studio 代码运行 x = 5 y = 10 z = 15 if x > 0 and y > 0 and z > 0: print("All conditions are true.") else: print("At least one condition is false.") 在上面的示例中,如果x、y...
first string is empty, so it will become False inside if condition. not will convert False to True. Hence statement inside the if condition is executed. second string is not empty, so it will become True inside if condition. not will convert True to False. Hence statement inside the else ...

python if condition: # 条件为真时执行的代码块 else: # 条件为假时执行的代码块 3. 执行流程 for 循环: 初始化一个迭代变量。 每次迭代时,迭代变量从可迭代对象中获取下一个值。 执行循环体内的代码块。 当可迭代对象中没有更多元素时,循环结束。
Executing the above code will return the following output: Great! This was what we expected. Now the next step is, what if the condition turns out to be False and we then want to print something *(or anything else)? *This comes out as the"else "conditional statement in Python. ...
Apparently, Python has an automatic way of creating a four-space indentation whenever you combine a two-character keyword likeif, a single space, and an opening parenthesis. Therefore, there is no need to add extra indentation in the condition break. ...
