Python uses indentation to define a block of code, such as the body of anifstatement. For example, x =1total =0# start of the if statementifx !=0: total += xprint(total)# end of the if statementprint("This is a
Python uses indentation (white space at the beginning of a line) to delimit blocks of code. Other languages, such as C, use curly braces to accomplish this, but in Python indentation is mandatory; programs won't work without it. As you can see, the statements in the if should be indent...
“If” statements evaluate any condition that you pass to it in the same line. This is mostly selfexplanatory. If the condition you pass evaluates to “True” (a Boolean value which we’ve discussed in the last post), python will run the following code within the if statement. Likewise, ...

Learn how to use if/else statements in Python with step-by-step examples, best practices, and common mistakes to avoid.
Example 3: Using OR Operator With Python elif Statement In the following example, the “OR” operator is used with multiple “elif” statements. It returns the boolean value “True” if either of the conditions is satisfied: Code: Number = 72 ...

If Statements Mark as Completed ifstatements are used for truth value testing. In this lesson, you learned that you don’t need to explicitly compare a value toTrueorFalse, you can simply add it to theifstatement: Bad Python ifvalue==True:print'truthy'ifvalue2==None:printNone ...
NESTED IF STATEMENTS 嵌套的if语句则是在一个if语句的代码块内部包含另一个if语句,可以实现更复杂的逻辑判断。 四、BOOLEAN LOGIC AND CONDITIONS 在考虑if语句的条件时,可以使用布尔逻辑操作,如AND、OR和NOT来构建更复杂的条件表达式。这还包括对变量进行比较操作,如等于、不等于、大于、小于等。
Python nested for loops and for loops and if statements combined.They are not necessarily considered to be Python basics; this is more like a transition to the intermediate level. Using them requires a solid understanding of Python3’s logic – and a lot of practicing, too.There are only ...
