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(...
In the following example, we have two loops. The outerforloop iterates the first four numbers using therange()function, and the innerforloop also iterates the first four numbers. If theouter number and a current number of the inner loopare the same, then break the inner (nested) loop. ...

嵌套列表是指一个列表中包含其他列表作为元素的数据结构。嵌套列表可以有任意层级的嵌套,即一个列表中可以包含其他列表,而这些列表又可以包含其他列表,以此类推。 如: nested_list = [[1, 2, 3], [4, 5, 6], […
