all() 方法返回 True 当给定的可迭代对象中的所有元素都为真时。如果不是,则返回 False。 您可以在此处的 python 文档中阅读 更多 相关信息,并 在 此处 阅读更多信息和示例。 (我在这里也用这个信息回答了类似的问题 ——How to have multiple conditions for one if statement in python) 原文由 burkesquires...
IF-ELSE --> CONDITION2: condition1 is false and condition2 is true IF-ELSE --> ELSE: all conditions are false 上面的关系图展示了多个if else语句的逻辑关系,当条件1为真时执行第一个代码块,当条件1为假且条件2为真时执行第二个代码块,当所有条件都为假时执行最后一个代码块。 多个if else语句的...
Logical Operators to Add Multiple Conditions If needed, we can use logical operators such asandandorto create complex conditions to work with anifstatement. age =35salary =6000 # add two conditions using and operatorifage >=30andsalary >=5000: print('Eligible for the premium membership.')else...
Python if statement can have multiple 'and' to combine conditions. section Example Python ```python num = 10 if num > 0 and num % 2 == 0 and num < 20: print("Number is a positive even number less than 20.") ``` 在上面的旅行图中,我们展示了Python中if语句可以有多个’and’来组合...
Multiple conditions 类似这样的多个if/elif/elifs,如何向量化呢? 你可以调用np.where在任何情况下,代码长了就变得有点难读了 实际上有一个函数专门可以做多重条件的向量化,是什么呢? 5 numpy.select() 向量化if...elif...else。更简洁(甚至更快)和做多重嵌套np.where。
You can also have multiple else statements on the same line: Example One line if else statement, with 3 conditions: a =330 b =330 print("A")ifa > belseprint("=")ifa == belseprint("B") Try it Yourself » And Theandkeyword is a logical operator, and is used to combine conditio...
if (DieOne == 6) and (DieTwo == 6): num = str(num) print('You got double 6s in ' + num + ' tries!') print() break TLDR 在底部。 首先,如果以下条件为真,则 while 循环运行,因此 DieOne != 6 or DieTwo != 6: 简化后必须返回 true,以便 while 函数运行 ...
if x > 10 and \ y < 5: print("Both conditions are true.")```在这个例子中,使用反斜杠使if语句的条件继续到下一行,光标回到行首。5. 在字符串中使用反斜杠进行转义:在Python中,字符串中的特殊字符可以使用反斜杠进行转义。例如:```my_string = "This is a \"quoted\" string."```在这个例子中...
if (this_is_one_thing and that_is_another_thing): # Since both conditions are true, we can frobnicate. do_something() # Add some extra indentation on the conditional continuation line. if (this_is_one_thing and that_is_another_thing): do_something() (另外可以参考下面的考虑:关于换行符...
