因为one-line if确实需要else来跟踪它。尽管如此,当我在上面的脚本中添加else (在if之后):over_30 = [number 浏览23提问于2020-03-09得票数 0 回答已采纳 1回答 期望keyword_do的单行if-else语句 、、、 我已经使用单行if- and语句很长一段时间了,就在最近,我还反复地得到这个错误:这是我在当前示例中使...
You can also have anelsewithout theelif: Example a =200 b =33 ifb > a: print("b is greater than a") else: print("b is not greater than a") Try it Yourself » Short Hand If If you have only one statement to execute, you can put it on the same line as the if statement....
一行版: # One-line版 result = [x for x in mylist if x % 2 == 0] print(result) # [2, 8, 12]五、一行代码将列表转换为字典 使用Python的enumerate()函数,可以在一行中将列表转换为字典。将列表传递给enumerate()函数,并使用dict()函数将最终输出转换为字典格式。
这个One-Liner 片段将向你展示如何在一行中使用 While 循环代码,我已经展示了两种方法。 #方法 1 Single Statement whileTrue:print(1)#infinite 1 #方法 2 多语句 x = 0 whilex < 5:print(x); x= x + 1# 0 1 2 3 4 5 3、一行 IF Else 语句 ...
result = [x for x in mylist if x > 250] print(result) # [300, 400, 500] 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 2 一行 While 循环 这个One-Liner 片段将向你展示如何在一行中使用 While 循环代码,我已经展示了两种方法。
In certain situations, theifstatement can be simplified into a single line. For example, number =10ifnumber >0:print('Positive') Run Code This code can be compactly written as number =10ifnumber >0:print('Positive') Run Code This one-liner approach retains the same functionality but in ...
if .. elif .. else statement When there are multiple conditions to check, you can use the elif clause (short for "else if"). Python evaluates each condition one by one until it finds one that is True. If none are True, the else block is executed. ...
# target is expected to be one of x, y, or z, and nothing else. if target == x: run_x_code() elif target == y: run_y_code() else: run_z_code() 假设这个代码现在是完全正确的。但它会一直正确吗?需求改变了,代码也会改变。现在要求改变为当 target == w,执行 run_w_code。如果...
