3. Using a While Loop You can also use awhile loopto iterate over the elements of a tuple in python. The while loop continues to execute as long as the value of the index is less than the length of thetuples. In the below example, inside the loop, theprint()statement displays the ...

Here, you used a while loop instead of a for loop. The reason for this is that it’s not safe to iterate through a dictionary with a for loop when you need to remove items from the dictionary at hand. You continue this until the dictionary becomes empty, and .popitem() raises the ...
在上面的代码中,我们使用了游标(CURSOR)来逐行读取员工销售数据,并通过LOOP循环和WHEN结构来处理数据。 总结 WHILE循环是 MySQL 存储过程中的一个强大工具,它增强了我们处理数据的能力。通过控制逻辑、条件判断以及迭代,用户可以轻松解决复杂的数据处理任务。掌握WHILE循环将在数据库管理和应用开发的过程中提供重要支持。
In the code above, fruit acts as an iterator that the loop uses to traverse each list element while simultaneously printing them. The loop terminates after evaluating the last element in the list. The code above should give the following output: Apple Mango Peach Orange Banana 2. Iterating Th...
do和for很类似,也有do循环联合(do-while) loop循环 loop起初是个联合,起初CPL语言,年代:1963年;loop-to起初的是NetRexx,年代:1996年。 loop联合:CPL、SETL。 loop独立:Arturo、Clojure、Ada、Rust。 其中loop衍生是L循环。 repeat循环 repeat-with,起初是1987年,语言:HyperTalk,继承者:AppleScript、Lingo、Inform...
Method 2: Using a while Loop Awhileloop can also be used to iterate through a list in Python, although it’s less common than theforloop. Thewhileloop continues as long as a specified condition is true. Example: cities = ["New York", "Los Angeles", "Chicago", "Houston"] ...
Another approach is that - Iterate over the list usingfor ... inloop and insert each element at the 0thindex using thelist.insert()method. When a new element will be added at the 0thindex the previous element will be shifted to the next position. In this way, we will get a reversed...
