Using break to exit a loopPython's break statement is for exiting a loop early:>>> for string in strings: ... if substring in string: ... result = string ... break ... >>> result 'banana' This code works just like before, but it can even work from outside a function....
The break Statement: Exiting a Loop Early The continue Statement: Skipping Tasks in an Iteration The else Clause: Running Tasks at Natural Loop Termination Writing Effective while Loops in Python Running Tasks Based on a Condition With while Loops Using while Loops for an Unknown Number of Iterati...

Similar to “while” we can also use “break” and “continue” statements in “for” loop as well. Now we are done with the conditional statements and move forward with other structures. Modules Sometimes there is a need to reuse the code or manage it depending upon our requirement, this...
Breaking Out of a for Loop Prematurely There will likely be times when you require to exit the loop early. For example, if you hit a set of data or a specific requirement, you can break out of the loop and continue executing the rest of the code. All you need to do is use thebrea...

Since being created in the early 1990s by Guido Van Rossum, Python has been widely applied in system management and web programming. Python was developed from the ABC programming language, which was designed for nonprofessional programmers. Python also includes the advantages of Modula-3 and the ...
回溯法是一种通过尝试所有可能的解来找到问题解的算法设计方法。它通常通过递归实现,每一步选择一个可能的解,如果解不符合要求,则进行回退,尝试其他可能的解,直到找到满足问题条件的解。它通常应用于组合问题、排列问题、子集问题等。 回溯搜索算法尝试在每次递归时为变量分配一个值,如果没有更多要分配的合法值,则回...
