Python if statement is one of the most commonly used conditional statements in programming languages. It decides whether certain statements need to be executed or not. It checks for a given condition, if the condition is true, then the set of code present inside the ” if ” block will be ...
Python MultilineifCondition: Backslash at the End of Each Line Using a backslash (\) at the end of each line is a method to visually break a long line of code into multiple lines, making it more readable. This is particularly useful when dealing with complex conditions inifstatements. ...
If statement, without indentation (will raise an error): a =33 b =200 ifb > a: print("b is greater than a")# you will get an error Try it Yourself » Elif Theelifkeyword is Python's way of saying "if the previous conditions were not true, then try this condition". ...
Ifconditionevaluates toFalse, the body of theifstatement will be skipped from execution. Let's look at an example. Working of if Statement Example: Python if Statement number = int(input('Enter a number: '))# check if number is greater than 0ifnumber >0:print(f'{number}is a positive ...
Example -1: Use of multiple conditions with logical OR The following example shows the use of the where() function with and without the optional argument. Here, the logical OR has used to define the condition. The first where() function has applied in a one-dimensional array that will retu...
以下语句:print("first print"),if condition:,print("third print")具有相同的缩进级别,并且始终被执行。 在if语句之后,有一个缩进级别更高的代码块,其中包括print ("second print")语句。 如果if的条件为真,则执行print ("second print")语句。

max = a if a > b else b ## value_if_true if condition else value_if_false print(max) 2.枚举迭代(Enumerate)函数 enumerate()函数将一个可迭代对象加上计数器,并以enumerate对象的形式返回。当你想要遍历一个列表同时也想要跟踪索引时,这个函数非常有用。
If Elif Else in Python Here, the elif stands for else if in Python. This conditional statement in Python allows us to check multiple statements rather than just one or two like we saw in if and if-else statements. If first if the condition is true, then same as in the previous if ...
您清楚三元运算符的工作原理吗?基本上,name = something if condition else something-else。因此,如果condition评估为True,则将name分配为something,如果condition评估为False,则将something-else分配给name。 现在您已经了解了如何控制代码的路径,让我们继续下一个主题:循环。
