Python Nested if Statements It is possible to include anifstatement inside anotherifstatement. For example, number =5# outer if statementifnumber >=0:# inner if statementifnumber ==0:print('Number is 0')# inner else statementelse:print('Number is positive')# outer else statementelse:print(...
Nestedifstatements allow you to evaluate multiple conditions within a singleifblock. This is particularly useful when you need to check a series of conditions before executing a specific block of code. By nestingifstatements, you can create a more structured and efficient way to handle complex dec...
Nested If You can haveifstatements insideifstatements, this is callednestedifstatements. Example x =41 ifx >10: print("Above ten,") ifx >20: print("and also above 20!") else: print("but not above 20.") Try it Yourself »
Once you are feeling comfortable with theif,elif, andelsestatements, you can move on to nested conditional statements. We can use nestedifstatements for situations where we want to check for a secondary condition if the first condition executes as true. For this, we can have an if-else stat...
Nested If Statements Although the indentation of the statements makes the structure apparent,nested conditionalsbecome difficult to read very quickly. In general, it is a good idea to avoid them when you can. Logical operators often provide a way to simplify nested conditional statements. For exampl...
for iterating_var in sequence: for iterating_var in sequence: statements(s) statements(s)Python while 循环嵌套语法:while expression: while expression: statement(s) statement(s)你可以在循环体内嵌入其他的循环体,如在while循环中可以嵌入for循环,反之,你可以在for循环中嵌入while循环。
Python Conditional Statements Test your understanding of Python conditional statementsIntroduction to the if Statement We’ll start by looking at the most basic type of if statement. In its simplest form, it looks like this: Python if <expr>: <statement> In the form shown above: <expr> ...
Beautiful is better than ugly.Explicit is better than implicit.Simple is better than complex.Complex is better than complicated.Flat is better than nested.Sparse is better than dense.Readability counts.Special cases aren't special enough tobreakthe rules.Although practicality beats purity.Errors should...
elif是“else if”的缩写。elif语句数量不受限制；若有else语句，其必须在最末尾，但是不一定要有else语句，如：每个条件按顺序检查，第一个false，则到下一个；其中某一个为true，对应的分支就会执行，然后语句结束。不管有多少条件为true，只执行第一个为true的。4.7 嵌套条件（nestedconditionals）一个条件可套...
Python programming language provides the following types of decision-making statements. Let us go through each decision-making statement quickly. Single Statement Suites If the suite of anifclause consists only of a single line, it may go on the same line as the header statement. ...
